Review on S4 100 Street Multi Channel Amplifier by Scott King

I used a small amp to replace a Hifonics 1200W 4 channel Class A/B amp and somehow with less gain my car got a lot louder! I also have a BOSS crossover with even lower gain than the Hifonics amp. I don't have to go over 25 on my Pioneer Dual Dyne when I used to always have to go to 30. All my Hifonics class A/B amps; 1600 watts 4ch, 600 watts 4ch, 1200 watts 4ch run really hot and go on the defensive at what appears to be the most conservative of settings, and this amp can do them all! Most importantly, I can get more mids through the amp without killing it like the Hifonics. I had my doubts about a 4 channel class D amp because I've always heard that because the class D amp draws current you degrade the sound quality. Smaller size, class D, no heat, noisy, clean. I don't understand why there are no reviews for this amp. Don't argue, just get this amp!
