Kicker KXA400.2 KX Series 400w 2 Channel Class D Full-Range Amplifier

Powerful, dependable, and good-looking

Kicker's 2-channel KXA400.2 amplifier will bring brilliance and clarity to your sound, powering a pair of speakers with 100 watts RMS each. This reliable and compact KX 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. Building a big system piece-by-piece? You could start by using this amp in 1-channel mode to drive a sub with 200 watts, and then later switch the amp back to 2-channel operation in order to power the speakers when you get a bigger amp for the sub.

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.

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, as the steeply sloped high- and low-pass filters offer a wide range of adjustment. The filters 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 — to optimize the signal for midrange speakers in a 3-way system.
