Mono Subwoofer Amplifiers

Mono amps are generally used for extremely low frequencies (ie bass) that are channeled into a single or multiple subwoofers. If you really love your music and you want to get the best out of your car audio/stereo system; you'll be amazed at the difference a mono amp and a subwoofer will make. When choosing an amplifier for your application, remember that it's usually better to use a more powerful amplifier with the gain controls turned down for better reliability.
