48KXMA5004 500 Watt 4-Channel Marine Amplifier

The KXMA500.4 is a Class-D marine amplifier built for the outdoors, with gain, crossover, and bass-boost controls protected behind a gasket-sealed panel to keep moisture away from key settings. It delivers 125W per channel at 2 ohms stereo (75W x 4 at 4 ohms, or 250W x 2 bridged), with 700W of dynamic power for headroom during loud passages. FIT2 fail-safe integration circuitry and a DSP-controlled preamp keep the signal clean, while a gain control with a Gain Match LED indicator takes the guesswork out of setting levels correctly the first time. KickEQ variable bass boost adds up to 6dB of extra low end on the second amp channel, and a full-range RCA output lets you daisy-chain another amplifier to a KICKER KMC Media Center without running new signal cable. Every KXMA amp meets the Real Marine standard, with anti-corrosive speaker, power, and RCA terminals, stainless-steel screws, a conformal-coated circuit board, and ABYC/NMMA-compliant power connections, all tested against UV, humidity, and saltwater exposure. A black anodized aluminum chassis and top-mounted teal LED light pipe round out an amplifier built to survive marine conditions while still looking good doing it.
