The KXMA series amplifiers are designed for outdoor adventures. Featuring gain, crossover, and bass-boost controls protected behind a gasket-sealed panel, alongside a control cover hiding the settings, they create a water-resistant barrier to key controls.

Real Marine™

The KICKER Real Marine standard ensures that your amplifier is purpose-built for your boat. Each 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.
