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-206 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 then 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.

Well, after much debate and research I opted to go with this amp over a variety of others. VERY glad I did. Amp birth sheet read 2608 watts @ 2 ohms. LOTS of power from this thing and pretty efficient too. Runs cold @ 4 ohms and on a stock electrical my voltage never reads below 13.0v. under heavy load. Definitely worth every single penny.

I have it drawing signal through the Kicker line-out converter tapping signal from my factory subs in the rear deck. This amp actually has a setting where you select which input you are using so there is no need to run a remote wire if going the route I did.

I recommend this amp because it is ridiculously loud I got 2 15" L7 kickers wired at 2 ohms and I had to put lock tight on the nuts and bolts of my spoiler cause it almost fell off.
