Great Amp!!!!!
This is a great amp I have it hooked up to a P3 and it pounds. It produces good clean power without distortion. This amp is not overrated, it puts out what it says it does. Would recommend this amp to anyone that wants a great amp for the price.

Great Sub Amp
Got this Amp running to a RF T1 and it pushes it nice and hard. Amp is a lot wider and longer then I thought it was going to be for only 750 watts.

Perfect For 2 subs
I have 2 of these running 2 10" DVC 2 ohm subs per amp, thus I'm running each amp at 2 ohms and my subs are 250wrms ea and that's what there getting, hasn't missed a beat and sounds very good. Blue light look great too.

Power from the Gods
Great sound, I have this baby pumping to an 12" Alpine type X and it sounds amazing. Clear and crisp Bass. This is the 2nd Hifonics Amp I bought and this by far is one of the best.

Awsome Amp
I bought one of these amps at a local audio store and the definate first thing you notice is how big and heavy these are! If you have very little space than that could be a bad feature, but I personally like it. It is very loud, I am powering 3 subwoofers off of it at 1ohm. It has so far been very reliable too.
