General Info on Home Heating Furnace

The home heating furnaces are usually used in the homes, offices and several other commercial areas. You should keep some important things in your mind, while buying a furnace. The most important and crucial point for the furnaces is to buy home heating furnace from a licensed professional. The licensed professionals can install the furnaces carefully and these furnaces can be cleaned easily. Any part of home heating furnaces can also be changed very easily. If any furnace specialist advises you to replace the furnace, you may be overwhelmed by the vast range in the modern furnaces. The efficiency of the modern furnaces can be measured by the AFUE (Annual Fuel Utilization Efficiency). The minimum efficiency of the home heating furnaces was in the era of 1992. The modern home heating furnaces units have at least 78% annual fuel utilization efficiency.

An electric furnace is costly, but it is always harmless. The gas furnace is unsafe, because there is always a possibility of leakage and this leakage could be hazardous. The leakage of gas generates carbon mono oxide, which is very hazardous for health. The gas furnaces have two general categories of competence, condensing furnaces and power furnaces. The annual efficiency of the power furnaces is at least 80 to 82% and at least 90% of the condensing furnaces. The condensing furnaces are more reliable and more efficient than the power furnaces. The condensing furnaces need very few oil to operate. The heating capacity of the condensing furnaces is very suitable for the homes. Most home heating furnaces are outsized. Bigger furnaces are less efficient and very expensive to operate. The installation of large home heating furnaces is not easy as compared to the small furnaces.

Some companies are selling both the outdoor and indoor heating furnaces and wood burning furnaces. The installation cost of the wood burning furnaces is more than other types of furnaces. The corn fuel furnaces are also very economical and efficient. The corn furnaces need daily cleaning for efficient results.

There several different kinds of furnaces available in the market. The home heating furnaces can be bought from the market at very low and reasonable prices. There is lots of information available in several different magazines and guides, about the home heating furnaces.

Islamic Credit Cards

All forms of banking contain several risks that pose a challenge to banks and management authorities. Islamic banks, like other conventional banks, are financial institutions providing services to depositors and investors and financing companies, public sectors and individuals. Therefore, Islamic banks are subject to the risks similar to those confronted by conventional banks. While Islamic banking has been around for several decades, originating from groundbreaking efforts from the Bahrain, Malaysia, Iran, Sudan and Egypt. At the foundation of Shariah compliance there are two concepts of profitability in Islamic banking: profit and loss sharing and mark-up. Islamic banking is based on the totally Riba (interest) free and there is no transaction involving the interest. In the profit and loss sharing the rate of return on the financial assets is either not known or fixed before the undertaking; in case of mark-up the purchase-resale transaction is determined with reference of the benchmark rate of return. Profit share involves the bank’s ability to secure a high return arises from its own investment decision and input post-investment. By comparison, in conventional banking the borrower of the money become responsible for the entire risk. Poor investment decisions by the bank have a direct bearing on the returns gained by depositors, as the rate of return is determined by the profit-and-loss sharing ratio.

Shariah-compliant instruments differ from conventional banks’ offering in the legal contracts, governance and the liquidity structure.

Moving from evolutionary stage, institutions are structuring and offering a wide range of financial instruments and exploiting new modes of financing and market. On consumer financing side, Islamic credit card based on tawarruq offers all features of a credit card, easy purchases and repayments through a series of commodity transactions. Islam allows the use of credit card so long it does not engage the factor of usury. As an example if the withdrawing cash advance from the credit facility will result payment of an interest, it is forbidden. In the same way if there is an additional interest charge due to delay in payment, it is forbidden also. Therefore, if the credit card works as a charge card, where you only pay the principle amount that you use plus the service charges, it is permitted. However, there are certain questions still to be answered; how does Islam accept the role of credit card as a medium of payment? What are the underlying principles required by Shariah in the functionality of credit card? What would be the possible legal issues and how Islam addresses these issues? What are the differentiation factors in the Islamic credit cards?

Credit cards concept is allowed by the Shariah, if it does not involve the element of usury because 'Allah (SWT) permitted sale and prohibit usury'. AmBank Bank Berhad offered Islamic Credit Card in Malaysia called Al-Taslif and it was launched in 1992. Shariah concept of Bai Inah is being used in Malaysia for issuing Islamic credit cards. Bai Inah is defined as back-to-back sale and purchase transactions entered into, whereby in the first transaction, the bank sells items to the customer on a deferred payment basis keeping some profit. In the second transaction, the bank will repurchase the same asset from the customer at purchase price, which is lower than the selling price, on cash basis (card’s limit), and the difference between the purchase and the selling price is the bank’s ceiling profit. Now ABC Islamic Bank has launched its Islamic credit card named Al Buraq in Bahrain. Maybank Islamic has also rolled out its lkhwan Card, new Islamic credit card series. The cards feature either the international cards franchise of American Express or Visa International. Similarly, Dubai Islamic Bank (DIB) has also launched its first Islamic credit card with the support of Card Tech Limited, a leading UK-based bankcard systems provider and processor.

The expert, who specializes in Islamic law and transactional jurisprudence, considers that the burden of the responsibility belongs to the banks’ Shariah committees that support banks to offer such services which are commonly prohibited by the majority of present-day Muslim scholars. Most banks offering credit cards do so with the purpose of getting interest - which is sternly and clearly prohibited by Islam.

The expert went on to warn people against falling into the trap of the supposed Shariah-compliant cards which begin effectual advertising campaigns nowadays. Moreover, the only Shariah-compliant credit cards are the charge cards which only a limited number of banks offer.

In the meantime, the Shariah committees in banks have issued their defenses in the face of the charges leveled against them and the debate is still ongoing. The expert also explained that credit cards represent a guarantee by the bank to the customer, particularly in places such as hotels which rely more on credit cards than they do on cash.

Looking beyond domestic shores, the Islamic cards based on the Bai Inah concept might not be able to penetrate the Gulf markets, which insist that Bai Inah is not a sufficiently strong basis for issuing Islamic cards. The Banker reported that the concept is ethically flimsy when applied in this manner as the sale transacted is a fake sale and thus, just a means of masking riba. Therefore, the structure or basis for Malaysian Islamic cards has been criticized for not being wholly Shariah compliant as compared to Islamic cards issued by Bahraini banks.

The conflict boils down to differences of belief. There are many interpretations within Islam on what is acceptable, given that the schools of thought on Shariah law are not homogenous. However, local Islamic bankers have referred this conflict to the National Shariah Advisory Board, which ruled that the Bai Inah transaction is indeed acceptable. Malaysia follows the Shafie school of madzhab, which approves the Bai Inah transaction for Islamic cards as it conforms to all the essential elements of a valid sale.

The Islamic cards, like their conventional cousins, are tied to international payment systems companies such as MasterCard and Visa, therefore they offer international recognition and access to ATMs worldwide.

The future of Islamic cards is indeed bright in Malaysia as there is demand for it. The market for Islamic cards is huge and growing in response to the government’s urge to introduce more Islamic financial products in Malaysia. It will take a while for consumers to understand the structure of the products, but once they see and appreciate them, the growth rate of the Islamic products is going to be even better. There is a substantial Muslim population in Malaysia and a number of them seek Shariah compliant products and services. As an aggressive promoter of Islamic banking and finance, AmIslamic Bank is optimistic about the demand for Islamic products including Al-Taslif Card.

Islamic credit cards are emerging tool for the Islamic banking profitability. Now Islamic cards are widely used in Gulf and the popularity is increasing but different banks uses different laws and rules to support their activities. However, in Pakistan the concept of Islamic credit cards is not introduced yet. There is need of one common rule for the Islamic credit cards to solve the controversy and make it a useful tool for the Islamic banking era.

Profitability in Islamic Banking

Introduction

All forms of banking contain several risks that pose a challenge to banks and management authorities. Islamic banks, like other conventional banks, are financial institutions providing services to depositors and investors and financing companies, public sectors and individuals. Therefore, Islamic banks are subject to the risks similar to those confronted by conventional banks. While Islamic banking has been around for several decades, originating from groundbreaking efforts from the Bahrain, Malaysia, Iran, Sudan and Egypt. According to McKinsey & Co, a management consulting firm, the value of Islamic banking industry is around some $750bn with over 300 dedicated institutions and thousands of Shariah-compliant banking service windows operating in more than 75 countries. Islamic banking and financing has gained a strong grip both nationally in Muslim countries and internationally in the financial world. Regular degree programs are also being offered at the university level almost in all parts of the world.

Profitability Concepts

At the foundation of Shariah compliance there are two concepts of profitability in Islamic banking: profit and loss sharing and mark-up. Islamic banking is based on the totally Riba (interest) free and there is no transaction involving the interest. In the profit and loss sharing the rate of return on the financial assets is either not known or fixed before the undertaking; in case of mark-up the purchase-resale transaction is determined with reference of the benchmark rate of return. Profit share involves the bank’s ability to secure a high return arises from its own investment decision and input post-investment. By comparison, in conventional banking the borrower of the money become responsible for the entire risk. Poor investment decisions by the bank have a direct bearing on the returns gained by depositors, as the rate of return is determined by the profit-and-loss sharing ratio.

Shariah-compliant instruments differ from conventional banks’ offering in the legal contracts, governance and the liquidity structure. The various Islamic financial products practiced in different parts of the world are described below.

Mudarabah

Mudarabah is a kind of contract in which one partner provide money to another partner for investing it in any commercial enterprise. The investment comes from the first partner who is called "rabb-ul-mal", while the management and work is an exclusive responsibility of the other, who is called "mudarib". In this contract bank finance the customer and share the profit or loss.

Murabahah

Murabahah is actually a term of Islamic Fiqh and it refers to a particular kind of sale having nothing to do with financing in its original sense. If a seller agrees with his purchaser to provide him a specific commodity on a certain profit added to his cost, it is called a "murabahah" transaction.

Most of the Islamic banks and financial institutions are using "Murabahah" as an Islamic mode of financing, and most of their financing operations are based on "Murabahah". That is why this term has been taken in the economic circles today as an instrument of banking operations, while the original concept of "Murabahah" is different from this assumption.

Musharkah

'Musharakah' is a word of Arabic origin which literally means sharing. In the context of business and trade it means a joint enterprise in which all the partners share the profit or loss of the joint venture. It is an ideal alternative for the interest-based financing with far reaching effects on both production and distribution. In the modern capitalist economy, interest is the sole instrument indiscriminately used in financing of every type. Since Islam has prohibited interest, this instrument cannot be used for providing funds of any kind. Therefore, 'Musharakah' can play a vital role in an economy based on Islamic principles. The proportion of profit to be distributed between the partners must be agreed upon at the time of affecting the contract. If no such proportion has been determined, the contract is not valid in Shariah.

In spite of all the benefits, Musharakah is almost nonexistent in the Islamic banking and finance markets due to various complexities.

Salam

Salam is a sale whereby the seller undertakes to supply some specific goods to the buyer at a future date in exchange of an advanced price fully paid at spot.

This mode of financing can be used by the modern banks and financial institutions especially to finance the agricultural sector. In Salam, the seller undertakes to supply specific goods to the buyer at a future date in exchange of an advanced price fully paid at spot. The price is in cash but the supply of purchased goods is deferred.

The only problem in Salam which may agitate the modern banks and financial institutions is that they will receive certain commodities from their clients, and will not receive money. Being conversant with dealing in money only, it seems to be cumbersome for them to receive different commodities from different clients and to sell them in the market. They cannot sell those commodities before they are actually delivered to them, because it is prohibited in Shariah.

Istisna

Istisna is a sale transaction where a commodity is transacted before it comes into existence. It is an order to a manufacturer to manufacture a specific commodity for the purchaser. The manufacturer uses his own material to manufacture the required goods.

In Istisna, price must be fixed with consent of all parties involved. All other necessary specifications of the commodity must also be fully settled.

Istisna can be used for providing the facility of financing in certain transactions, especially in the house finance sector. If the client has his own land and he seeks financing for the construction of a house, the financier may undertake to construct the house at that open land, on the basis of Istisna, and if the client has no land and he wants to purchase the land also, the financier may undertake to provide him a constructed house on a specified piece of land.

Ijarah

"Ijarah" is a term of Islamic Fiqh. It means 'to give something on rent' or 'to lease'.

It is defined by jurists as: "Possessing of a usufruct for a consideration"

When interest-free financial institutions were established in the near past, they found that leasing is a recognized mode of finance throughout the world. On the other hand, they realized that leasing is a lawful transaction according to Shariah and it can be used as an interest-free mode of financing. Therefore, leasing has been adopted by the Islamic financial institutions, but very few of them paid attention to the fact that the 'financial lease has a number of characteristics more similar to interest than to the actual lease transaction.

All these financial tools are being used by Islamic banks and financial institutes along with some other instruments to earn profit. Interest is modified in different forms in these tools of Islamic banking for earning profit.

Future of Islamic Banking

Now Islamic banking industry faces issues of a different sort. That is, how to consolidate the gains made so far and sustain itself, ward against any meltdown and grow. But Islamic banks will become pure financial institutions that fill financial gaps standing in the way of real economic transactions at the grassroots level. Islamic banking will be ethical banking for, among others, the following reasons: Islamic banks will stay away from financing Shariah-proscribed activities like producing alcohol or financing speculative activities, for example. There will be transparency in their transactions with the clients, depositors as well as fund-seekers due to compliance with the Shariah.

While the number and operations of Islamic banks are fast expanding, this segment of the market is still small relative to the appetite for Islamic finance. Pakistan, in light of its past experience, is launching a gradual and steady approach to Islamic banking. Despite rapid expansion in industry, the share of Islamic banking in the total banking system is a modest 3.2%.

Findings

Islamic banks need to be integrated globally as global financial markets, encourage competition, and provide a proper climate for ongoing innovation. Islamic banks then can consolidate their position in a range of markets and provide products for more customers.

Islamic banks will need to grow at least by 40-50% annually with its promising prospects and potential to be able to raise its share from 3.5% to about 15% of the total banking system. Given that banking industry as a whole has been growing at a substantively fast pace, the level of effort required for Islamic banks would have to be steeper to claim this share. Given the success of some countries in achieving this share for Islamic banking, it is important that concerted efforts are put in to propel Islamic banking system further and deeper in Pakistan.

Wiring of Car Stereo System

An important part of your whole car audio system consists of just wires. There are variety of cables and wires concerned in installing a car audio system. You have power wires, amplifier cables, speaker wires, power capacitors etc. It is always better to be prepared with at least the basic know how before you go in for car audio system installation. Do it yourself installers are recommended to read the owners manual and basic instructions about the car audio installation anyhow, it’s not a tough job at all. The power wire is an essential part of the amplifier installation. Select the suitable measurement of the wire and fusing. An accurate wire gauge avoids the amplifier from being choked off by the size inadequacy of the power wire.

Always choose power wires with lots of strands, so that all the wires are easier to install and don't be damaged while passing through the various corners and obstacles of the car. The covering jacket of the wire should be of a material, which can easily resist different types of chemicals like oil and battery acids, which can easily cause destruction on poor quality wires. You can go for wires, for installation with large number of strands for the car audio speaker wires. The wire jacket is not that important in this case, because the speaker is not positioned in areas where it could stumble upon chemicals, as in the case of power wires. Oxygen free copper wiring is always suggested for car audio speaker wires for durability and long lasting performance. The measurement of the speaker wiring depends on the power going in to your speakers from the amplifier and the total length between the amplifier and the speakers.

Signal cables are also known as RCA cables and suppose to be important for their noise elimination properties. Try and go in for a good quality RCA cable for your car audio system, which would guarantee trouble free and better performance in the long run. RCA cables are good choice and more reliable way to have extra performance from the car audio system. It is suggested that you go in for "twisted pair" cables for your audio system as they are better at noise reduction. It is unnecessary to say, the quality of wires connecting the car audio power capacitors and batteries should also be good. Make sure you have a good ground wire connection. Be sure that RCA cables or signal wires are running away from any power wires or sources in the car, and are not run side by side to them. One can find widespread information on car audio wiring by visiting online resources on the topic. Possibly car audio professionals and experts are best placed to offer you great advice on car audio wiring. Many online car stereo resources helps a lot in this regard to guide the do it yourself customers for wiring their car audio system properly.

Optimize Your Car Stereo Frequncy Bands

An audio crossover is a type of audio filter generally used with audio systems especially in Hi-Fi audio systems. Usually the loudspeaker drivers used in audio systems are not capable to control the whole sound spectrum. So here the crossover plays a significant role and splits the audio signals in different frequencies bands, which can be handled by individual loudspeaker drivers. The combination of different frequency band is normally the pattern of Hi-Fi audio systems. An audio crossover may also be constructed mechanically and is normally used in full-range speakers, portions of whose cones or dust caps are decoupled at increasingly higher frequencies. There is another use of crossover called multi-band processing. Here audio signals are split into bands which are adjusted individually. After that these separate bands are mixed together again for instance bass enhancement, multi-band dynamics, multi-band distortion and high frequency exciters.
A perfect crossover splits the incoming audio signals in different frequency bands that do not interact. After that they are added together again.

There are many types of crossovers available in the market but all these types fall under the classification that is provided below.
Classification based on components:
- Passive crossovers.
- Active crossovers
- Mechanical crossovers
- Digital Crossovers
Classification based on filter order:
- First order crossovers
- Second order crossovers
- Third order crossovers
- Fourth order crossovers
- Higher order crossovers
- Mixed order crossovers
Classification based on circuit topology:
- Parallel crossovers
- Series crossovers

A passive crossover is normally used in the signal path after the amplifier. It is a type of a capacitor or coil installed right on your speaker lead. For installation of passive crossover first of all you need to remove your speakers from its location. Disconnect the positive lead of your speaker. There you connect the bass blocker. Then connect the positive lead to the other head of bass blocker, test its operation and reinstall your speaker.
Let’s take a look on the available crossovers manufactured by a well-known manufacturer Kenwood.

Kenwood KE-600 Crossover: It is a versatile and most of the advance crossover available in the electronics market now a day. It is a six way cross over for Hi-Fi audio systems having built in parametric equalizer and DC to DC power supply for high voltage outputs and low noise. It has variable level controls, different phase switches and subwoofer output from 30Hz to 800Hz.

Your Car Stereo System Needs Line Driver

A line driver is an amplifier used to develop the communication consistency of a normally digital intrafacility tinny transmission line, over unlimited distances, by driving the input signals to the transmission line with a higher than normal signal level, in telecommunication sector. In Mobile Audio systems, a line driver is a small amplifying device used to boost the power of the audio signal coming from the head unit. The newly reinforced signal is then transmitted to its suitable amplifier. Gain on an amplifier requirement to be set with the consideration to the input voltage the amplifier spots, the lesser the input voltage, the bigger the gain to create a certain loudness and higher the sound quality. When increasing a very low voltage signal, the noise floor of the amplifying system increases, meaning that the amplifier is not only amplifying the low voltage acoustic signal, but also the low voltage noises pulled out in the line along the way.

By using a line driver, gains of the amplifier must not be set at high level, thereby amplifying the acoustic signal with less of the low level noise. This function of the line driver can be useful especially in long runs of signal cable, which are more horizontal to picking up noise. Line Drivers facilitate long distance connections between one source and one destination, and are used to preserve video quality when driving video signals over long cable runs. Video signals normally lose amplitude and high frequencies on long coax cable runs. Line drivers provide variable gain control which can be adjusted to boost the video signal, compensating for the overall drop in signal voltage. Line Drivers are very useful devices that help much to enhance the overall performance of the car stereo systems. Line drivers permit the signals to go from the source to the output device easily. Line drivers are very high-tech and functional devices that widely used with car stereo system to improve the performance.

There are variety of Line Drivers are available in the market in different types. Line Drivers are available in different power ranges, sizes and price ranges as well. You should choose the Line Driver that is most suitable to your car stereo specification. Line Drivers are very cost effective and functional devices that take your music experience to the next level. Line Drivers are not only available at local car stereo stores but also at online car stereo stores at affordable prices. Online car stereo stores offer great deals on Line Drivers of different companies. You can buy all type of Line Drivers from online car stereo stores at very low prices as compared to the local market. You can also read reviews on the Line Drivers of different companies at various online sites and car stereo magazines.

Equalizer Gives You Full Control Over Sound

Today car audio system is considered essential part of your vehicle. With the help of the latest technologies, manufacturers are able to produce high quality car audio systems that can produce clear, noise free and loud sound. Basically a car audio system is a device which plays track. To produce high quality sound there are numerous components involved and a good car audio system must have an equalizer to set the frequency of sound according to your own taste. However a car audio system has a complex mechanism. Primarily an equalizer enables users to set the different frequency bands in an audio system and a user can see the frequencies either geographically or digitally depending on the model of equalizer. A general car audio equalizer consists of several audio filters and each audio filter is centered on a particular frequency in the audio-range.

The term "equalizer" is normally but imperfectly used as a common word for audio filters. DJ mixing equipment and hi-fi audio components often include so called graphic equalizers or simply equalizers.

Different Types and Uses of Speakers

Car speakers are an essential part of the car stereo system. The function of the speaker is to take up the signals from the power amplifier and deliver them to you in the form of music. Car speakers are usually used in cars for the reason of keep away the stress of driving and to have relaxation and avoid being bored while traveling from one place to another. It’s of course an element of the stress management while driving the car. But remember don’t make frantic others by increasing the volume of your car stereo speakers. When it comes to car audio systems, there are varieties of different kinds of speakers that must be joint for best quality sound:

Multi-Element – This type of speakers also known as coaxial speakers, multi-elements hold two different types of speakers that are built into one. A big cone (woofer) makes the low-range frequencies and round about 3 small cones (tweeters) control the high-pitched frequencies. The number of rudiments or components that are built into the speaker decides the number of "ways" the speaker is classified. For example, a car stereo speaker with a large cone (woofer) at the back and two small cones (tweeters) in the front would categorize as a "3-way" speaker.

Mid-Bass/Midrange – The Midrange speakers are usually designed and intended to pick up and reproduce the middle and some lower bass frequencies. Midrange speakers enhance the frequency of middle range and make sound better.

Component Speakers – The Component speakers are tweeters and horn-loaded compression drivers. They are designed to reproduce the high-pitch frequencies in your music. A tweeter above 25 kHz is considered a super-tweeter.

Sub Woofers - Sub woofers reproduce only the lowest frequencies such as the bass, and then intensify them amazingly. You need to select the amplifier and woofer supported for your car speaker and what you want to install in terms of a car stereo system. Mostly, car stereo speakers are installed with other items in such a way that they produce the maximum sound with high quality. But keep in mind that others may be bothered because of these “noise makers,” as these things are sometimes referred to. You can choose different types and brands for the front and rear end car speakers so that they mix together perfectly to produce better quality sound.

For example, you can select Oxygen sphere 100s for front speakers. You need to choose such kind of CD player that lets you to add characteristics in the future, and have a good amplification system and outstanding sound quality. You may or may not go in for a subwoofer. In such a case, it would be better if you choose full range speakers placed on a MDF parcel shelf. To utilize the free available space in a car, typically speakers are installed in doors. However, the quality of sound produced is sometimes compromised due to the service holes in the doors.

Power Adaptor an Essential Device

An external power adaptors are also known as power supplies, and are important for all small electronic devices. The electronic products like MP3 players, Personal Digital Assistants ( PDAs), camcorders, digital cameras, laptops, cordless and mobile phones get power from these adaptors. The U.S Environmental Protectio 3 Agency(EPA) and the US Deparment of Energy (DOE) has set strict energy efficiency guidelines with the Energy Star label. Many people prefer to buy the products which are entitled with this label.

If you want to convert DC power to AC then you should have proper device to make it possible. It is sometimes hard to find things but take this in consideration that what features are important and how to choose a unit neccesary for your vehicle. For this, you need a power inverter that is appropraite for your needs. There are two types of power inverters: true-sine wave or modified-sine wave ( square wave). True sine-wave can produce either identicle or a power better than public utility grid system. However, modified-sine wave and square wave are the most common types of inverters available in the market. It provides power that is sufficient for many devices. People prefer modified-sine wave power inverter for their ac/cell phone charger, laptop, fan or camers. Suqare wave inverter are appropriate for road tripper, fall into four groups. Power inverters upto 300watts, 600 watts, 1750 watts and 3000 watts are used for some specific household appliances. They usually connects via 12 volts plugs.

Ipod car adaptors are designed to work through an automobile’s audio sytem. Only MP3 adaptors can work with Ipods and ipod car adaptors are deigned for ipods.These are connected through the digital dock connector which is not only used to control the unit but also delivers the music to external system. However, the car power inverters keep you away from the hassle of cameras and dead cell phones batteries and keep your mobile charged all the time with its power. And also your kids remain clam with a TV which is runned by the power inverter in your car. We can also build our own power inverter and make them DC power to AC power by following few steps like: a 12 volts car or boat power inverter will change house power (DC) into car power (AC). Many power inverter manufacturers recommend hard wiring when using 150 or more watts of power. Mostly power inverters have a builtin fuse inside but still you can add an inline fuse as close to the battery as possible.

There are many companies who make power inverters. Likewise, Vector company enables automobiles, trucks and RV’s 12 volts DC system to convert to AC household current to run appliances.

Necessities for Car Stereo System

Car stereo systems can comprise many necessities besides the head unit, amplifiers, and speakers for improving the performance. What are these other necessities? There are so many necessity parts that you may not know of, but normally, car stereo necessities include signal processors, wiring, fuses, line drivers, distribution block, and batteries, just to name a few. There is certain piece of equipments in hooking up a car stereo system that you must have in order for it to function. Even with a necessary sub woofer system, you still require the proper wiring and a fuse that can handle the power without anything starting a fire, melting or getting blown. Car stereo technology has achieved great heights with the rapidly developing technology of this era. The advanced technology is allowing audiophiles to improve their audio systems consistently.

There is absolutely wide range of other parts you want to hook up with your car stereo system to ensure that it works properly and according to your expectations. For example, appropriate wiring and fuse are necessary to hold on the power required by that subwoofer. This will help to avoid power deficiency, overheating or melting of your wires, which will cause your new set of subs significant damage. Proper organization of your car stereo parts and connections should be considered to get that long-lasting high quality sound from your car audio.

The car audio wiring is as essential as any other component of a car stereo system. Why? It’s simple, the wires connect everything. If you don’t opt for the accurate sized wire for your audio system, it may not work properly and could make some noise and distortion. On the other hand, you may choose the correct size and suitable power to control your fuse’s amperage rating. But if your connections are not organized carefully, either showing wires that can cause accidents or having crossed wirings, then you would not be able to get the most out of your car or home audio system. It can even cause the equipment to burn. Connections are just as significant as any other necessities for your car audio system, such as how everything in your audio system is connected. Your wires should be connected correctly with the wire terminals for a more reliable connection and good performance. It comes in variety of sizes to fit any gauge of wire or speaker’s inputs.

Features and Functionality of Amplifiers

There are some important key features that you should look for when shopping for an amplifier for your car stereo system. Depending on what you are going to hook your amplifier up to, there are quite a few different impedance loads available for the amplifier. If you are only hooking up to a subwoofer for the car deck, I suggest a Class D amplifier that is easily bridgeable and has an impedance of 2 ohms. For a whole car stereo system, I recommend a multi-channel amp with the typical impedance of 4 ohms. Power of the amplifier is measured in watts. The maximum high power is the most that it can send out. If you are going to be pounding your car stereo amplifier incessantly for long periods of time, then look for an amplifier with a high maximum RMS power for better performance.

All kind of amplifiers have a signal to noise (S/N) ratio which is measured in decibels (dB). It distinguishes between the levels of the signal to the level of background noise. The higher the signal/noise ratio, the less background noise there will be. Some amplifiers with 2 channels have a tri-way output protection. These kinds of amplifiers also called dual mode, this system can easily control a pair of stereo speakers and a single subwoofer at the same time from the outputs of a single 2 channel amplifier. This is an inexpensive way to drive a subwoofer. It also needs an outer tri-way adaptor that is connected in-line between your amplifier and the speakers. Four-way adaptor is also available for amplifiers for higher performance.

A variety of amplifiers also have a subsonic filter which eradicates the very low bass that the human ear can't hear. This results in better performance in the amplifier’s power supply. The lower the THD (total harmonic distortion), the less change there is in the overall sound of the signal and higher the performance of the amplifier. Frequency response is very important thing that should be considered before you purchase an amplifier for your car stereo system. Frequency response is a term used to explain the way a speaker reproduces the electrical signal fed into it. Frequency of amplifier Measured in a range of Hertz (Hz), the wider the range is, the better the frequency response is and higher the quality of sound. The more direct power there is, like for a subwoofer, the less frequency. It is good to find an amplifier with a built-in crossover to keep high level of frequencies from reaching a subwoofer, and low frequencies from reaching the smaller speakers. A low-pass crossover will only let the frequencies that are less the crossover point to be amplified. A high-pass crossover only lets the frequencies that are higher than the crossover point to be amplified. This will allow for better efficiency out of all your speakers.

Their prices also vary on the basis of functions, features and output quality. Car amplifiers are available from US $ 50 to 1000. Car amplifier comes in various sizes depending on the number of channels. An amplifier can be as small as 1 channel amplifier to as large as 8 channels amplifier. The 2 and 4 channel amplifiers are very popular among people. However mono subwoofer amplifiers are also getting much popularity in cars stereo system.

Car amplifiers have built in features such as equalizer, speaker level input, active crossovers and signal processing. While purchasing a car amplifier keep it always in mind that all amplifiers don’t have the same power rating. Some low quality brands may mention high power ratings but don’t give the desired output. This is the main reason to select a well-known brand to avoid such abnormalities.
Some features of car amplifier are as follows that need to be considered when you to purchase a new one:

Bridgeable: With this feature a pair of amplifier power channel is combined into one channel for greater power.
Channel: This feature offers flexibility. Especially in the sense of options, in future up-gradation and add-ons.
Class: This feature identifies the way on which an amplifier operates. This feature is rarely found in car audio amplifier.
Connectors: This feature refers to the method of attachment of wires that are connected with amplifier and other equipments like speakers and power wires.
Power Supply: The two most general types are IC chip and MOSFET supply. IC chip is mostly used in head unit and is able to produce 20 watts per channel while MOSFET is the most famous design and is able to produce high quality sound as compared to IC chip.

Sound Blaster Car Stereo Subwoofer

The car stereo subwoofer is an essential device and an integral part of a good audio system. The Subwoofer is basically a type of speaker that is used to create the frequencies around 100Hz. The Subwoofers produce high quality of bass that can make you rocking. The true beat of quality woofers provokes to shake your body on hi-fi music. Ordinary speakers are unable to produce such quality of sound and high frequencies effectively as the woofers do because there are size limitations of drivers. The Subwoofers come in various sizes but generally a subwoofer is considered an 8-inch speaker that requires more amplifier power to produce quality sound than ordinary coaxial speakers. Moreover a car stereo subwoofer also requires an enclosure to produce high quality sound effectively.

Car Stereo Line Output Converter

Line output converter can be defined as a small device that converts high-voltage speaker-level signals to preamp-level signals; which is acceptable to an amp. If u want to connect an amp to your car stereo which doesn’t have a speaker level inputs then it means you need a line output converter to have a preamp outputs. So you can connect your receiver to an amp by converting your receiver’s speaker output into preamp-level signals. It consists of a transformer and (10 to 20 watts) a high-voltage resistor and connects to amp by using RCA patch cable. The amplifier in the head unit is being loaded by the resistor. It has also an adjustable gain feature to pull output. Most of the line output converters have wire to ground the transformer. When the head unit is “on” the voltage on the output speaker wires, is almost half of the DC battery and changes rapidly when it is “on”. Whereas, when the unit is “off”, the voltage is 0 volt DC. As we already said, that the head unit’s outputs has a large quick increase in DC voltage when the head unit is turned on. The transformer will provide the variation of voltage between the two input terminals. Since the DC voltage increases at the same time on both the input terminals, then the rhythm of the DC is irrecoverable. There are different types of Line Output Converters available in the market but Gizmo Peripheral is remained the industry leader in high quality LOC’s.

There are simple Instructions for the line output converters which need to take in consideration. So connect the audio cable speaker’s leads to the device from the car stereo. The line output converter then trims down all the inwards bound speakers’ level audio signals until the outgoing signals get adjusted to the preamp inputs on the amplifier. An adaptor scosche performs many different applications. It accepts speaker level outputs and converts them to preamp level outputs. It has a fader control feature also that means; we can hook 2 channel amplifier or 4 channel amplifier easily and can not lose any fader control.

Adjustable line output converters helps to convert the radio speaker level output to the lower amplifier RCA level input. Installers use to convert their speaker level stereo to RCA levels with the help of Hi/low adaptors which hooks to an external car stereo amplifier. Hi/low converter with 2 channels and 4 channels are also available with or without adjustments. It is important to note that the match between your car stereo and amplifiers are the same. Adjustable hi/low converters allow to fine tune the hi/low device to match levels in the car and are the most popular in adjustable output converters. There are many adjustable output converters in 2 channels and 4 channels available. For example, Soundgate “LOC A” adjustable high performance Hi/Low adaptor features full DC isolation and handles 40 watts and Soungate “XR4”, this performs dual functions such as to add an aftermarket receiver to a factory amplifier system or to add four channel amplifiers to a factory receiver. This feature can make adjustments on all four channels.

Affected by market demand, the companies are also introducing the latest technologies day by day. There are lots of companies all over the world striving to manufacture the latest car audio systems to attract more consumers by offering incomparable audio equipments. A car audio speaker is a vital part of a car audio system. The main purpose of car audio speaker is to covert audio signals in its electrical form to a pressure wave that we can perceive as sound. The major use of a car audio speaker is to allow all components of car audio system to do their work without adding any change in the original sound quality.

Generally just one side of an audio speaker is satisfactory to produce the entire audio spectrum. But unluckily, a speaker that can produce low frequencies has too much mass to be able to produce the higher frequencies. For this, there are specific speaker drivers that take care of particular frequency bands. For instance, subwoofers are used to produce the extreme lows of music with the impact that can be felt as well as heard. The car audio speakers also make great impact on car audio system and help produce high quality sound.

Energy Co-operation is Necessary for Development of SAARC Countries

Energy is the key ingredient of the socio-economic development of every country and every region. SAARC member countries are very poor but also the fast growing in the world so, energy is crucial part for the development of these countries.

South Asian region has basic feature of growing economies and high population growth rate on the other hand, per capita energy consumption of the region is least in the world. A huge population of this region is using the traditional and inefficient energy resources that are also polluting the environment. All the countries also have low per capita income which lacks the access to the advanced energy sources which are expensive. This region is facing the challenge of poor energy state to meet the requirements. Oil import is increasing in the SAARC countries and also there is a need of heavy investments for the development of energy market, which itself another challenge for the region. In SAARC countries, energy was neglected in measures to support the economic development for a long time. However, it has a key role in the three dimensions of economic development which are:

Social Dimension (fight against poverty)
Economic Dimension (security of supply)
Environmental Dimension (environmental protection)

Demand of energy is very high in the South Asian countries and the rate of growth of consumption is three to four times higher than developed countries. SAARC countries are using coal and certain renewable energies (conventional biomass) instead of oil gas and nuclear energy. Biomass is frequently used that raises the risks for health and environment.

There is a great need for the development of power market within the SAARC countries. But there is lack of investment in the energy sector because these are developing countries and the public sector could not afford alone. Private sector investments must therefore be attracted. All SAARC member countries are dependent on imported energy which is likely to increase due to fastened economic growth, if in the meantime no major discoveries of oil or gas are made. Energy import bill will go higher, also because of increased oil prices .Cooperation in the demand side of the energy in the SAARC countries is one the most promising avenues of the approach. SAARC countries must cooperate to manage the energy demand more effectively for the survival through measures which support energy efficiency. However, this needs sufficient funds, advanced technologies and a propitious legal and financial framework. Cooperation in the management of energy supply can lead to greater stability in the energy sector.

In South Asia the need of energy particularly electricity, is rapidly growing. Improved electricity supply is a key for economic growth and improving social services.

Electricity is not available around the 1.5 billion population of the SAARC member countries, especially in the rural areas, which adversely affects the efforts to reduce poverty and create better opportunities for all.

National energy systems are autarchic with weak or non-existent interconnections. There is little cross border trade of electricity, with the exception of India-Bhutan trade, and none in natural gas.

Energy resource surplus South Asian countries (Nepal and Bhutan, Central Asian countries, Iran and Myanmar would surely benefit from energy export-led growth and accomplishment of large-scale regional projects which otherwise would be infeasible; those with considerable energy export requirements (Pakistan, India, Sri Lanka and Afghanistan) would enhance energy security as would the other (Bangladesh) from improving the energy mix.

A two-track approach:

(i) Enhancing energy trade through specific projects, whether bilateral or multilateral.
(ii) Strengthening regional organizations and institutions, to complement the first track, help augment mutual trust and confidence, and develop conditions for scaling up.

There are two regional energy trading hubs, one at the western flank of the region, consisting of Pakistan, Afghanistan and north-western India as importing markets of energy that trade with Central and Western Asia. The other hub is at the Eastern flank of the region consists of Bangladesh, Nepal, Bhutan and Sri Lanka. Both hubs could develop steadily, with India eventually bridging the two hubs into a region-wide integrated energy market.

SAARC could play a key role in helping build mutual trust, integrated energy market, build up regional institutions and physical infrastructure, and partner with development organizations.

Differing resource endowments, development requirements, and demand patterns among the SAARC member countries and its neighborhood create considerable opportunities for cooperation and trade in the energy sector and – eventually, for creating one of the world's largest integrated energy market. Without the cooperation in the energy sector SAARC member countries are not able to secure their future and their high dependency on the other countries for the import of energy increasing the bills and darken the ways of the economic development. Its is essential for the SAARC member countries to cooperate with one another in the energy sector and provide the financial and technical support to each other in order to create the integrated energy market and brighten the ways of economic development for the future.
