Kicker 44KXA800.5

5-channel car amplifier — 50 watts RMS x 4 at 4 ohms + 400 watts RMS x 1 at 2 ohms


Delivers dependable power to your whole system with style

The days of needing a couple of huge amps in your trunk are over. Kicker designed the KXA800.5 five-channel amplifier to run your entire system, powering four speakers with 50 watts RMS each, while driving a sub with up to 400 watts RMS. This reliable and compact KX Series rocker remains cool even when pushed hard, thanks to its high-mass heatsink, high-tech internal components, and efficient full-range Class-D amp technology. Not worried about rear speakers? You could also use this amp in 3-channel mode to send 200 watts RMS each to some high-performance components up front, and still run your sub with 400 watts.

Connection perfection

Kicker employs their Fail-Safe Integration Technology (FIT2™) to reject noise and stop any interference generated by your car’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, even a factory system. 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.

Kicker KXARC

Very cool wireless remote

Kicker includes their KXARC Bluetooth® wireless remote control with this amplifier. From the driver’s seat, you can adjust the level of the sub channel, add bass using Kicker’s SHOCwave™ bass restorer, switch sub phase, and get warnings when the sub channel clips.

Versatile controls behind the folding door

A folding door gives you easy access to your amp’s controls. You can tune for almost any kind of speaker system, as the steeply-sloped high- and low-pass filters offer a wide range of adjustment. The filter section for Amp 2 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. Activate that bandpass filter, and you can use the amp to drive a 3-way system — Amp 1 channels running the tweeters, Amp 2 the midrange speakers, and the Sub channel the sub.

The subwoofer channel includes a bass boost for adding some kick to your music, along with a subsonic filter that eliminates the extra-low, inaudible frequencies that only waste your sub’s energy.
