KMA300.4 4-Channel 75Watt x 4 @ 2 Ohm Marine Class-D Amplifier

Big sound meets big value. Use this flexible four-channel KM marine amplifier to power your system with ease and pump up the sound like only KICKER can!

Enjoy your music while you’re cruising

A little power goes a long way in making your day out on the water more fun. Kicker’s KMA300.4 marine amplifier can power four speakers with 40 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 power, this amp can go into bridged, 2-channel mode and put out up to 150 watts RMS per channel, for a couple high-performance tower speakers, for example.

Tone controls for the best sound

High-pass crossover filters guard against low-frequency distortion in 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.
