Kicker 48KMA600.4 360w 4 Channel Class D Full-Range Marine Amplifier

Serious power on your boat

Great music can really add to the fun of an afternoon on the water. Kicker's 48KMA600.4 marine amplifier can power four speakers with 75 watts RMS each, so you'll hear your music clearly over the sounds of the wind and waves, in up to 2 zones on your boat. You could also use this amp to power a system consisting of two speakers and a subwoofer. If you're just interested in serious power, this amp can go into bridged, 2-channel mode and put out up to 300 watts RMS per channel, for a couple of high-performance subs or tower speakers, for example.

Audio tools

High-pass crossover filters keep distortion caused by bass frequencies out your speakers. A low-pass filter and a bass boost on each channel help sculpt the tone when you're powering subs.

Shrugs off salt and water

Kicker knows how rough things can get at sea — they built this amp weather-tough, with marine-grade speaker terminals, stainless-steel screws, conformal circuit boards, and ABYC/NMMA-compliant power connections. That last one is a certification from the National Marine Manufacturers Association (NMMA), so you know that these connectors are well-made and will work well for a long time, even in rough seas.
