Enjoy your music while you're cruising

Kicker's KMA450.6 marine amplifier can power six speakers with 40 watts RMS each, so you'll hear your music clearly over the sounds of the wind and waves, in up to 3 zones on your boat. You could also use this amp to power a system consisting of two speakers for the deck, for example, and two speakers plus a subwoofer for the cabin. If you're just interested in power, this amp can go into bridged, 3-channel mode and put out up to 150 watts RMS per channel, for two high-performance tower speakers and a sub, for example.

Tone controls for the best sound

High-pass crossover filters on all channels guard against low-frequency distortion in your speakers. The "Amp 3" channels feature a low-pass filter and bass boost to shape the tone for a subwoofer. It also features a wired remote, so you can control the level of bass from the pilot's seat.

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 those connectors are well-made and will work well for a long time, even in rough seas.
