KXMA Amplifiers
KICKER gives you a full suite of purpose-built KXMA-Series Marine Amplifiers, all built to deliver the volume and clarity you need on the water.

Power Pack
Available in two, four, five and eight-channel options, these Class-D amplifiers deliver as much as 1,200 watts – all while requiring an incredibly small footprint.

Tuned In
No matter where you mount your KXMA amp, this easily accessible 24dB crossover lets you quickly tune your system to perfection. To get the most out of your bass, a variable 24dB subsonic filter is featured on the five-channel amp.

Made for the Water
Following KICKER Real Marine™ protocol, power terminals meet stringent ABYC/NMMA standards, while thick gasketing protects the control cover from unwanted moisture. Even the aluminum chassis is UV-treated for extra-long life. All KICKER marine amplifiers also utilize conformal-coated circuit boards to protect the heart of the amp from water damage.

Craft Your Sound
Big power comes with big control. An adjustable 24dB crossover is featured on our marine amplifiers, as does KickEQ+™ bass boost for that extra bump.

Bass Knob
Tune your bass to perfection on the five-channel KXMA900.5 bass channel with the wired bass knob.

It’s Lit
Get the absolute most out of your amp with a specially designed gain control that lights up when the perfect input signal is detected from your radio.

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."
