This is by far the best bang for your buck as far as 4-channel amps go. Great sound, although not as good as you probably would get with a Rockford 4-channel amp. However, RF amps that are comparable to this in wattage and channels are over $400.00! This one is only $89.99! It amps the speakers great, and at the same time has little distortion rates. I couldn't believe it when I hooked it up, because I thought for sure, because of the price and all, it would be a very poor sound quality. This isn't the case at all. If I was to buy a 4-channel amp, and don't want to spend tons of money on one, I would for sure go with this one, or it's newer brother: the Crunch P900.4. It's almost the same thing from what I have heard. Only drops the number of watts down from 125W @ 4 ohms to 115W @ 4 ohms. Not much of a difference. Also, this one has one preout set (RCA Outputs), so you don't have to waste a spot on the back of your deck (or if you don't have room for another set).

All in all GREAT AMP, CHEAP TOO!
