Why Choose Kicker Amplifiers:

Kicker Always Exceeds Rated Power

Kicker Performance Audio has been around since 1980 and has been producing amazing products since then. Kicker’s drive to consistently produce products that not only are great but also push the standards of the car audio industry is very apparent in all series of their amplifiers. All Kicker amplifiers are CEA-2006 Compliant, assuring you are receiving a continuous certified RMS power rating. Kicker will always exceed the rated power because Kicker is notorious for under rating their amplifiers. So really you will be getting more power than you actually pay for, which is not true for other lower end performance amplifiers that generally over rate their amplifiers. Kicker amplifiers will provide a choice of three automatic turn-on modes; remote, DC offset, or signal sense, which make them compatible with any car audio system. Along with their high-density convection heat sink for extreme heat dissipation and high efficiency MOSFET power supply, Kickers amplifiers are great way to go when selecting the perfect amplifier for your car audio system.

Kicker FIT Fail Safe Integration Technology

Kicker Fail Safe Technology (FIT):

Kicker has manufactured a new Fail-Safe Integration (FIT) technology into all of their amplifiers. The FIT technology uses isolated differential inputs in order to reject noise or electrical interferences, caused by engines, alternators or any other audio or video component throughout your vehicle. The differential inputs will use a muting circuit that will block out any additional noise that may stream down the line. The FIT technology will help created the cleanest and purest sound possible for any audio system. The Kicker FIT technology is setting the standard for high quality sound.

Great little amp

Don't look at the price tag on this amp, It doesn't matter. This amp is worth every penny. It may not put out a crazy amount of power, but it will make your subs hit. I love this amp and have powered every pair of subs I've owned on it. Great amp, great buy. Highly recommend.

The best Amp I ever heard

When I want to SWAT (Stereo West Audio Toys) for their birthday bash, I bought a pair of 12 Kicker comp since it was buy one and get one free. With my luck, the Kicker rep was showing off what Kickers can do among other things. I originally was going to buy a DX amp, or I was going to go to inPhase and buy a Alpine MRX mono.

The Kicker rep told me to buy the ZX400.1. I thought it was a great deal since it was on sale and I never regretted buying it.

I would say if anyone was looking for a great mono amp, BUY THIS ONE.

Kicker 11zx400.1

I purchased this amp for my 3rd Generation Alpine SWR-1242d, I received the spec sheet that said it gives over 483 watts. I strongly recommend this amp for a ported setup. It really gets my Type R 12 moving!

Great Amp

Puts out alot more than it says and does get a little warm but thats the same with any amp. Make sure you have good airflow under it. I would recommend this amp to anyone looking for quality products

awesome amp

To start off, I had this amp for a long time and never had one single problem with it other than a few times went into protection mode from being hot, but was a really hot day out when that happened. I would recomend this because it's compact and overall really good looking. It performs like a champ, and will push your subs to the edge so if you're looking for an amp that will get the job done then look no further kicker has it.

Awsome AMP

This little amp really puts in work, I received it on 11/4/2011 installed it 11/5/2011 and I have already fallen in love. The fact that I only had to run the power wire from the front, no remote turn on wire. The amp turns on by sound signal detection witch is an awesome feature. This is a great Amplifier. Also, Sonic Electronix is my go-to dealer! You guys are just as awesome as this amp, Thank you Sonic!
