KICKER 48KMA8001 800 Watt 1-Ohm Marine/Boat Mono Sub Amplifier+Amp Kit KMA800.1

This bundle pairs the Kicker KMA800.1 mono marine amplifier with a Rockville RMWK4 waterproof wiring kit, covering both the amplifier and the cable needed to install it. The KMA800.1 uses a Class-D power supply to deliver 800W at 1 ohm, with 1200W of dynamic power for headroom during loud 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, and a full-range RCA output makes it simple to add a second amplifier later without running new signal cable. Real Marine ABYC/NMMA-compliant power connections and 316L stainless-steel hardware keep corrosion off the table through years on the water. The RMWK4 wiring kit is built specifically for wet environments, with tinned-OFC RCA cable, 4-gauge power and ground cable wrapped in poly woven mesh for chemical resistance, mini-ANL fuses rated at 80 and 120 amps, and all the terminals and cable ties needed for a clean run from battery to amp. Together the two pieces give a boat's subwoofer dedicated, reliable power without the guesswork of sourcing wiring separately.
