outstanding quality for the price June 25, 2009

Don't waste your time looking for other brands. If you want the best quality and power for your car audio system, get ROCKFORD. I replaced my 600W sony 4 channel amplifier for this one, and let me tell you, there is no comparison. I connected 2 120 W sony speakers and bridged a 400 W Sony Subwoofer...the sound from the speaker is loud and clear (similar to what I was getting from the Sony amplifier)...But the sound that I'm getting from the subwoofer is just amazing - and its only halfway of the power (the whole car shakes when on)...I strongly recommend this product and wont never go back to brands like sony or pioneer for amplifiers
