AudioControl ACX-300.4 4-channel powersports/marine amplifier — 50 watts RMS x 4

Waterproof power

One of the main issues with powersports amplifiers used to be that the amp wouldn't survive a thorough washing of your vehicle after a good day of dirty fun. AudioControl's ACX-300.4 four-channel amplifier carries an IPX6 waterproof rating, which means you can clean it off with a powerful water jet spray and it won't hurt a thing. Construction details include conformal circuit board coatings, insulated gaskets for the control panel cover, and waterproof input, output, and power connections.

Play your music loud and clear

The ACX-300.4 can send out 50 watts RMS per channel — plenty enough to hear your music clearly over the sounds of wind and motor. Like it loud? This amp can also operate in two-channel mode to power a pair of high-performance speakers with 150 watts RMS each.

Some practical features

This tiny, hand-size amp will fit almost anywhere in almost any kind of vehicle, and it features high-level inputs with signal-sensing turn-on, so it'll work with almost any stereo system. To simplify setup, a "Maximized" LEDs indicate when you've set the amplifier's gains for optimum performance.
