4-channel marine amplifier — 50 watts RMS x 4 at 4 ohms
Kicker expertise in a marine amp
The key to building a great marine amp is building a great amp, period. When Kicker designed their KXM line, they used the company's popular Kicker KX car amps as a starting point. Kicker KXM amps combine first-rate technology with water-resistant, protective hardware outside, so they're ready for life on the water.
Kicker's KXM400.4 4-channel amplifier can supply 4 speakers with up to 50 watts RMS each, so you'll hear all the beauty and brilliance of your favorite songs over the roar of the wind and water. This reliable and compact amp remains cool even when pushed hard, thanks to its high-mass heatsink, high-tech internal components, and efficient full-range Class-D amp technology.
Building a marine system for your boat and wondering what to buy first? You could use this versatile amp in 2-channel mode to drive a pair of subs with up to 200 watts each, then switch the amp over to power all your speakers when you get a bigger sub amp. Space can be at a premium on some boats, but this amp's compact exterior makes it easier to mount in tight spaces.
The RCA inputs on this Kicker amp will accept signal from just about any marine stereo.
No matter how snug the installation space, marine amps have to be tough enough to stand up to the marine environment. The KXM400.4 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. The all-weather protection even extends to the UV-protected heat sink finish.
The amp's RCA inputs accept speaker-level or line-level signals, so you can connect this amp to almost any stereo. Kicker even included a 3-second turn-on delay, which eliminates any annoying (and potentially damaging) turn-on pops.
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 section for the rear 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 to midrange drivers or other component speakers. The front and rear channels offer separate bass boosts, giving you more flexibility when you want to add some extra kick to your music.
