About Used Car Amplifiers

If you're looking to beef up the sound of your car stereo, a used car amplifier may be just the thing to get the job done. Car amplifiers can really drive your speakers, providing cleaner sound and clearer music without completely emptying your wallet. Used car amplifiers are especially beneficial if you're planning to fully customize your system, as purchasing several components new could be costly. As you begin your search for used car speakers, start by considering root mean square (RMS) power. RMS is a measurement of the power produced by a car amplifier. To prevent damage to your speakers, your amplifier's power should match your speaker and subwoofer rating.Car amplifiers fall under three categories. Mono amplifiers, the first type, are used with just one speaker. Two-channel amplifiers are used with a two speaker, one subwoofer combination. A four-channel amplifier can be used in signaling two speakers and a subwoofer or four speakers with two subwoofers. They can also be used in other configurations. If you are ordering a used car amplifier online, choosing a well-known brand may be a good idea. Some reputable brands include Alpine, MTX, and Kicker. Audiobahn, Phoenix Gold, and Rockford Foxgate are popular as well. You may even choose to purchase an extra used car amplifier. You can use two amplifiers for two different speakers. If you plan to arrange your system in this way, a pre-amp output is necessary for use with your extra amplifier.
