Kicker CX Series Amplifiers

Kicker CX series amplifiers were designed by Kicker's expert audio engineers to bring you plenty of clean RMS power for even the most demanding system. Kicker engineered these amps to be ultra compact, meaning there won't be any monsterous amps that you have to design your system around, they'll fit just about anywhere. The CEA-2006 compliant CX300.4 4-channel amp puts out up to 300 watts of RMS power and is compatible with the Kicker CXRC remote bass controller.

Kicker CX Amps are Incredibly Compact Ultra-Compact Footprint

The Kicker CX1200.1 will fit just about anywhere, whether you want to install it discretely under a seat, hide it in the back of your trunk or mount it somewhere else. This compact amp measures just over 7" wide, 12" deep and comes in at just over 2" tall. With a footprint this small, Kicker optimized the circuit layout for the most efficient use of components possible.


Kicker CX Amps Can be Mounted Nearly Anywhere Mount Anywhere

To take full advantage of the compact footprint, Kicker includes mounting hardware which gives you the option of vertically mounting your CX300.4 amplifier. With this hardware, you can install the amplifier nearly anywhere in your car, whether you're looking for an inconspicuous and out-of-the-way installation or want to mount your amp to show it off.


Kicker CX Amps Feature High Quality Components Staggering Technology

Beneath the high-mass, super cooling UV protected aluminum heatsink Kicker included double-sided fiberglass circuit boards and incredibly efficient Litz-wound transformers. Externally, the CX300.4 4 channel amplifier features buffered RCA outputs, noise-shielding metal-end panels and custom tooled power connectors.

Decent for a basic system

I have owned this amp for about a year now. This is a good entry-level amp for a basic system. I used it to power 6 Kicker 6" coaxials and 2 RF tweeters. System honestly didn't sound too bad, for being a budget system.

I have since upgraded to a JL Slash V3 300.4 amp and what a world of difference. Way cleaner sound, richer, much more power. But for $200, this really isn't a bad amp. I would definitely suggest an active crossover with this amp if you want clean sound.

Kicker cx 300.4 review

I bought this amp to push my Polk audio db 691 front and 651 rear I didn't think this amp would push the front well with 40 watts rms at 4 ohm but kicker always underrates there amps some mine was 341 rms total and this kicker amp is awesome pushes more then enough to them with the gain set at 65% and you get what you pay for kicker is more expensive then most but it's clear clean watts and I recommend 100 % I previously had alpine mrf 300 I honestly like kicker better

Simple amp with clean power

Class D technology has came a long way. The only full range class D I ever like was an Eclipse XA2000 with Bang and Olufsen ICEpower tech in it. While this amp isn't quite in the same class imo, it's a great choice from newer offerings. Currently running this amp on some JBL ms-62c components active off a DEH-80prs and sounds fantastic.
Not sure if it's from the amps "FIT" tech, or just got lucky, but I have almost an undetectable noise floor. No hum, buzz, whine, or anything.
Even at an underrated 40w, I set my gain to 40w, and it gets way loud before I get close to my max level, definitely good clean power!
