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
