Kicker's KMA150.2 2-channel amplifier pumps out 40 watts of clean power to two speakers to cut through the fog. If you want more kick on the low end, you can use this amp in bridged 1-channel mode to pump up a sub with 150 watts RMS. 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.. Marine-ready Kicker has made sure this amp will last, 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.
