Kicker

My system has plenty of power. Who needs an amp?

You might think you don't need an amp because you have a 400-watt system in your car, or because your new stereo puts out 50 watts a channel. But those are peak wattage ratings, which may boil down to 15 or 20 watts per channel, using the more realistic RMS rating. An amp sends your speakers the power they need to deliver your music with clarity and impact, whether you're using factory speakers or high-performance components. And low-frequency reproduction requires lots of power, so an amp is an absolute must if you're adding a sub to your system.

Our take on the Kicker 40KX800.1

by Buck Pomerantz

Delivers dependable bass with style

Kicker's KX800.1 mono subwoofer amplifier will power your bass with up to 800 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 the efficient Class-D amp technology.

Connects to virtually any system

Kicker employs their Fail-Safe Integration Technology (FIT™) 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 even thought to build in a 3-second turn-on delay, eliminating any annoying and potentially damaging turn-on pops.

Bass controls behind the folding door

You can tune for almost any enclosure and sub, and keep the signal clean, using the steeply-sloped low-pass and subsonic filters. A parametric KickEQ™ lets you choose a bass frequency to boost and also how many notes above and below that center frequency you can boost along with it, for some killer bass tone. And a wired remote lets you control all that level of bass from your front seat.
