The Kicker KXMA900.5 is a five-channel Class D marine amplifier engineered for powering a full speaker system plus a dedicated sub channel. It features FIT2 fail-safe integration circuitry, a DSP-controlled preamp, variable 24dB crossovers, KickEQ variable bass boost, conformal-coated circuit boards, ABYC/NMMA-compliant power terminals, and a black anodized aluminum chassis with gasket-sealed cover for controls.

Designed for marine installations, the amp offers high- and low-level inputs, a wired remote for sub control, bridged mono capability for the main channels, and rated power outputs including a 400W sub channel at 2 ohms. Settings are accessible under a sealed cover and stainless-steel mounting hardware is included for corrosion resistance in marine environments.
