I am using this amp to drive a set of Audiobahn ABC6003V 3 way components in my doors and a set of Audiobahn AS69Q 3 way 6X9s in the rear package tray. This amp is extremely clean and powerful and stays cool even at high volume.

This amp is powering two 4" * 6" speakers, each of which has a peak power of 120 watts; Two 5-1/2" speakers, with a peak power of 180 watts; Two 6-1/2" speakers, each with a peak power of 220 watts; Two one-inch tweeters with a peak power of 200 watts each. I have this amp running all of those components and it is not even turned all the way up. I have turned it all the way up once, and blew 4 of the speakers. This amp is the one you are looking for if you need a lot of power.

This is the most powerful 4 channel amp I have ever seen or heard. Before seeing this amp I had never seen a 4 channel that could handle this much power, and it's a great price.

I am using this amp in 4 channel mode for door speakers and it works great. Just to test the 3 channel mode, I hooked it up to a pair of 10 inch subs that are rated at 300w rms and it pumped them hard while driving the mids on 2 channels still. This thing is amazing. The built in crossovers on both front and rear eliminate the need for an external active crossover.
