I really like this amp. I have it driving my Infinity Reference components up front, and Infinity Reference coaxials in the back. This amp has great sound quality and seems to put out every watt of the advertised power, while barely getting warm to the touch in 4-channel mode. (I haven't tried it bridged into 2 channels yet.) The adjustable crossovers and remote bass EQ work flawlessly. It has good solid connectors for the inputs, outputs, and power cables. As someone who has broken and repaired many amps of varying quality over the years, I can say this one seems pretty solid physically, and it should hold up very well over the long term. The only caveat I have is that the first unit I got was defective (output was distorted for some reason). I believe one of the internal wires was pinched during the assembly process, but I never opened it up to verify that. Anyway, OCS replaced it under warranty with no hassles and the replacement has been absolutely perfect, so I am very happy with this purchase. Don't underestimate HIFONICS amps--for the money, I don't think you will find anything this good in other brands. And Online Car Stereo is a great place to buy!
