This flexible four-channel KM marine amplifier delivers big sound with a compact, efficient Class-D design. A variable 6dB KickEQ bass boost adds extra punch, while the 12dB crossover lets you dial in the perfect tune. Power up to eight speakers for a floating concert experience, with 150 watts RMS per channel at 2 ohms or 300 watts bridged. The conformal-coated circuit board and 316L stainless-steel hardware ensure it stands up to the marine environment. ABYC/NMMA-compliant power connections provide reliable, safe installation on any boat.
