Kicker KXMA500.4 Multichannel Marine Amplifier

KXMA Amps are built for the outdoors. Gain, crossover and bass-boost controls are protected behind a gasket-sealed panel, as is the control cover hiding the settings, creating a water-resistant barrier to key controls.

The Kicker REAL MARINEâ„¢ standard means your amplifier is purpose-built for your boat. Every KXMA (and KMA) Series amp comes complete with anti-corrosive speaker, power and RCA terminals, stainless-steel screws, conformal-coated circuit boards and ABYC/NMMA-compliant power connections. Kicker products also undergo rigorous testing to ensure they meet or exceed marine industry standards for UV, humidity and saltwater exposure. This unparalleled commitment to engineering quality and maritime safety is why their products truly are "REAL MARINEâ„¢."

KickEQâ„¢ delivers as much as an 6 dB of extra bump with a simple turn of the knob. A powerful 24dB crossover is also included, letting you quickly tune your system to perfection. A full-range RCA output allows you to easily add another amplifier without running new signal cable to your Kicker KMC Media Center (for example, KMC5 or KMC2).

RMS = Root Mean Square, measure of continuous power in audio devices

THD+N = Total Harmonic Distortion (THD, amount of unwanted frequencies, i.e., distortion) plus Noise (N, all sounds coming from the device other than the input signal). THD+N assesses device sound fidelity.

Important Safety Information

When installing Kicker amplifiers (car or marine) in a boat or other vehicle/environment where flammable fuel vapors can accumulate rather than dissipate, you must use appropriate MARINE fuses (such as, Kicker 47MRBF40, 47MRBF60, 47MRBF80, 47MRBF100, 47MRBF125, 47MRBF150, 47MRBF200, 47MRBF300), MARINE fuse holders (such as, Kicker 47KMFMF) and MARINE wiring (such as, Kicker 47KMWP050, 47KMWP4100, 47KMWP420, 47KMWP820, in red [47KMWPR] and yellow [47KMWPY]) to minimize the risk of fire or explosion.
