This is an excellent amp, I'm currently using it on two Hifonics HFX12D4. It gives them a fair amount of power not too little but a little less than what they should be getting.

The amps seems to put out 300 watts RMS at 4 ohms Bridged, Maybe just a little more. (350) 150x2 at 2 ohms and mid 70-100 at 4 ohms x2.

Worth the cost, clean sound, I'll be retiring this amp for two sets of 6.5 inch speakers.

Once I have the money to really step up into another level of car audio that is, until then this amp serves well.

The ONE thing I wish this amp had was a remote bass control rather than the bass boost on the amp itself, where I pretty much had to set it and leave it since I'm not gonna get out and go fiddle with the amp.
