Kicker KXMA900.5 4-Channel Full-Range Class D Marine Amplifier

Designed for demanding marine and powersports environments, this Class D amplifier delivers clean, powerful output with precision tuning at your fingertips. Gain, crossover, and bass-boost controls sit behind a gasket-sealed panel, protecting settings while keeping access simple, and a sealed cover maintains a water-resistant barrier. A variable bass boost adds up to 6 dB of low-end impact, while a steep 24 dB crossover lets you dial in seamless system integration. A DSP-controlled preamp, fail-safe integration circuitry, and a gain match indicator simplify setup. A wired bass controller allows instant level adjustment from your seat. Built with a black anodized aluminum chassis, conformal-coated boards, anti-corrosive terminals, stainless hardware, and marine-compliant power connections, it is engineered for UV, humidity, and saltwater resistance and long-term reliability.
