Play your bass loud and clear

It's always a problem finding a good spot for a sub amp in smaller vehicles. AudioControl comes to the rescue with their compact ACM-1.300 mono amp, which delivers up to 300 watts RMS to your subwoofer. This tiny, hand-size amplifier will fit almost anywhere in almost any kind of vehicle, improving the bass and the power of your music. Even better, it features high-level inputs with signal-sensing turn-on, so it'll work with almost any stereo system, even one using a factory radio.

Practical features

To simplify setup, a "Maximized" LED indicates when you've set the amplifier's gain for optimum performance. AudioControl's tunable AccuBASS circuitry restores and enhances the low-frequency punch in your system, which factory radios often attenuate to protect the stock speakers. An optional wired remote will let you control the bass level from the front seat of your car.
