Kicker 48KXMA800.4 400W RMS KM Series 2-ohm Stable 4 Channel Class-D Marine Amplifier

Gobs of power for fun on the water

Kicker's KXMA800.4 marine 4-channel amplifier will bring brilliance and clarity to your sound, powering four speakers with 100 watts RMS each. You can also set up this amp with two channels powering full-range or component speakers, and two channels bridged together to power a subwoofer with up to 400 watts RMS. This beefy amp delivers lots of solid wattages, no matter how demanding your speakers are.

Stays cool under pressure

This reliable and compact KXMA Series rocker will run cool even when pushed hard, thanks to its high-mass heatsink, high-tech internal components, and efficient full-range Class-D amp technology.

Made for marine use

The KXMA800.4 features a conformal-coated circuit board for improved water and dust resistance, plus corrosion-resistant power connections, a gasket-sealed front cover, and stainless-steel mounting hardware that won't rust all over your boat's gel coat or carpeting.

Connection perfection

Kicker employs their Fail-Safe Integration Technology (FIT2™) to reject noise and stop any interference generated by your boat's electronics, so you'll enjoy your music clean and pure. Speaker-level inputs make it possible to hook this amp up to almost any stereo receiver or radio. Kicker also helps you set this amp's gain properly, by offering free test tones for downloading. You play a tone and turn the gain up until the gain knob glows red. Then, you turn it down until it just goes out, and the amp's gain is set perfectly.

Versatile controls behind the folding door

A gasket-sealed front door gives you quick and easy access to your amp's controls. You can tune for almost any kind of speaker, as the steeply-sloped high- and low-pass filters offer a wide range of adjustment. The filter sections for the Amp 2 channels can be set up for bandpass operation — where both the high- and low-pass filters are engaged to allow only the frequencies between them to play — for optimizing the signal for midrange speakers in a 3-way system.
