Real Marine™

The KICKER REAL MARINE™ 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 our products truly are "REAL MARINE™."

KXMA800.4 Marine Amplifier

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. KickEQ™ delivers as much as an 6dB 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.
