Kicker KXMA900.5 900-Watt 5-Channel Class-D Marine System Amplifier with FIT2 and Wireless KXARC Remote
The Kicker KXMA900.5 is an all-in-one 5-channel Class-D marine amplifier engineered to power a complete, high-output audio system on your boat from a single, compact chassis. Delivering a stout 100 Watts RMS x 4 channels at 2 Ohms for your cabin and tower speakers plus a dedicated 500 Watts RMS x 1 channel at 2 Ohms for your marine subwoofer, this hybrid powerhouse provides the rock-solid foundation needed for high-impact open-water sound. Built strictly to Kicker's Real Marine manufacturing standards, the chassis features conformal-coated circuit boards, anti-corrosive ABYC/NMMA compliant power terminals, and stainless-steel hardware for total protection against humidity, UV rays, and harsh saltwater environments.
Fine-tuning your vessel's audio environment is seamless thanks to a gasket-sealed control cover that protects all active crossover dials, Gain Match LEDs, and DSP functions from moisture. The KXMA900.5 includes Fail-Safe Integration Technology (FIT2) to reject electrical engine noise and alternator whine, alongside the innovative KXARC Bluetooth wireless remote control to adjust subwoofer level, gain, and SHOCwave bass restoration directly from the helm. Outfitted with variable 24dB/octave crossovers, subsonic filtering, and KickEQ+ bass processing, this 5-channel solution delivers complete system control without cluttering your boat's storage compartments.
