KICKER 48KMA8001 800 Watt 1-Ohm Marine/Boat Mono Amplifier Sub Amp KMA800.1 [Open Box]

The KMA800.1 is a mono marine amplifier built to power a subwoofer with serious, reliable low end. A Class-D power supply delivers 800W at 1 ohm, with 1200W of dynamic power on tap for headroom during the loudest passages. A wired remote level control lets you adjust bass right from the dash, while a 12dB adjustable crossover and 24dB subsonic filter dial in exactly which frequencies reach the subwoofer. Variable KickEQ bass boost adds up to 6dB of extra punch at the turn of a knob, and a full-range RCA output makes it simple to add a second amplifier for mids and highs without running new signal cable. Real Marine ABYC/NMMA-compliant power connections and a conformal-coated circuit board protect the amplifier from moisture and salt air, and 316L stainless-steel hardware resists corrosion through years on the water. At just over 8 inches long, the amplifier fits into tight helm or under-seat compartments where space is limited. This is a straightforward way to give a boat's subwoofer dedicated power without complicating a system that already has an amplifier for the main speakers.
