my kicker certification came with its peak power at 670watt, which was the first great aspect, easy to install, though very large, its a beast of an amp. Works perfectly for any speaker system. I have always been happy with kickers product and this has definitely been a good one. Powering my Polk MOMO 6.5 Components and Polk MOMO 4x6's in my chevy truck. sounds amazing. this will give you the power you need for sure.

Had to send it back to Kicker inc to be fixed twice Idk why but I have had them for almost 2 years an some months an I can say they much stronger than the Infinity amps I had I love Kicker!! Cons to this amp is it gets very hot!! When I play it loud all the speakers connected to it are under the rms by maybe 20 30 rms so its not over powered its just very hot all the time an shut off when its reach that point where i can cook eggs on top of it.. needs a fan built in..
