Car amplifiers are available in two, four or five channels and in watt size from 50 to 500. Amplifiers “amp up” or boost the sound of your car’s stereo system. They can work incorrectly or stop working altogether for several reasons. If you installed the equipment yourself it might be easier for you to locate and fix the problem. If the dealer or someone else installed the equipment for you, it may take a little longer to locate and resolve problems.
