How to Check Compatibility Between Car Speakers and Car Amplifiers?

After buying a car the next question that comes to your mind is "What amplifier should I buy for my speakers?" Buying a complete car stereo system, car audio speakers, subwoofers and car audio amplifiers is a challenging task. It should be very much compatible with your car model as well.

For successfully operation of any system there should be perfect matching of car audio amplifiers to speakers. Each channel of the amplifier should be hooked to a single speaker or speaker pairs in case of component car speakers. This gives amplifier a 4 ohm impedance load, and is the most common speaker impedance in any car audio system. Load can be dropped to most amplifiers by wiring multiple speakers in parallel.

Not all of the amplifiers can drive speaker impedances below 4 ohms. Most of them can drive 2 ohm loads, not all. Few of the high current car amplifiers can drive loads of 1 ohm or less. Such an amplifier should be chosen that is capable of driving impedance that may have problems. By decreasing the impedance load on any amplifier not only increases power but also increases distortion, heat and also the life of your amplifier. By using a 4 channel amplifier or 2- channel amplifier you will retain front to rear fading, a stereo image, and distortion will be less and amplifier will probably last longer.

The car audio subwoofers do not need to be faded or wired in stereo. It can give more option for wiring our amplifiers. By proper planning the power out of amplifiers can be squeezed through the combination of speaker wiring and amplifier bridging.

The Bridging process of an amplifier means combining the power of two channels to drive one speaker. Typically it doubles the power of single channel although some of the top amplifiers will actually quadruple the power of a single channel. It is usually the most desirable and can be planned into your overall design. If for example two subwoofers are there in your system and you want to drive each of them with 100 watts you can do it.

No one wants to connect more than one full range speaker to any amplifier channel. But it is very much true that one can get more volume but you will also have to lose front to rear fading if it is required that your front and back speakers are run by a single 2 channel amplifier.

This article clearly explains car audio systems especially in detail about car speakers and car amplifiers.

I am not saying one can't drive without car music system but they provide an environment which you love your riding and I believe a world class music system and speaker do their work best.
