The extra boost you need

Boats can be noisy places. Kicker's KMA360.4 4-channel amplifier has the firepower you need for successful naval maneuvers, supplying 65 watts of clean power each to a broadside of four speakers. If you want to drop a serious depth charge, you can use this amp in bridged 2-channel mode to pump up a pair of subs with 180 watts RMS each. High- and low-pass filters help you get maximum performance from the speakers, while a variable bass boost lets you dial in the extra low end you're craving.


Kicker has made sure this amp will stand up to the life aquatic, with conformal-coated PC boards to protect against dust and water. The amp also features stainless-steel hardware so you don't have to worry about rusty terminals shorting out your good times on the water.
