AudioControl ACX-650.5

5-channel powersports/marine amplifier — 50 watts RMS x 4 at 4 ohms + 350 watts RMS x 1 at 2 ohms

Waterproof power

What's the point in installing an amp on your ATV if the amp won't survive when you spray off your vehicle after a day of fun in the dirt and mud? AudioControl's ACX-650.5 five-channel amplifier carries an IPX6 waterproof rating, which means a powerful water jet spray 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-650.5 can send 50 watts RMS each to four speakers and up to 350 watts RMS to a subwoofer — more than enough to hear and feel your music clearly over the sounds of wind and motor. Like it loud? This amp can also operate in three-channel mode to power two high-performance speakers with 150 watts RMS each while powering a sub with 350 watts. Selectable high-pass filters help you achieve the best tone possible for your full-range speakers. AudioControl's AccuBASS® processing plus low-pass and subsonic filters help you achieve the best bass tone possible for your subwoofer.

Some practical features

This tiny 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, LEDs indicate when you've set the amplifier's gains for "Maximized" performance. An optional wired remote lets you control the subwoofer volume from the driver's seat.
