Ive had this amp for about 8 weeks now. Pretty decent amp i have it powering 2 12in kicker cvr's. running at full power for 40 min it finally over heated never does for regular power though. My only problems is that with gain and level maxed i blew 4 fuses every time long low notes hit but not a problem turned to half way. Overall pretty good amp for the money.

I absolutely love this amp! I was a bit afraid that I wouldn't be getting enough power to the sub by running it 8 ohms and bridging the amplifier... boy was I wrong! It pounds! It is well worth the money and puts out plenty of power

This amp is by far exceeding my expectations. I was a bit skeptical at first, but I thought that I would give it a try. I have this amp hooked up to 2 Kicker 07C104 10" Comp subs in a sealed box, They hit hard! The amp doesn't even seem to be getting hot at all. After running for at least 20 minutes on multiple occasions, the amp is still cool to touch.
