Had this amp, and recently got stolen. Ran it to two 12s at 2ohm and pounded pretty hard, ran it to one 12 at 4ohm and pounded hard and had better sq then at 2 ohm. This isnt really billed as a sub amp, but as long as the subs are less than 1000w, this can easily push. Would note however, that it would cut out, but only after about 30 min of full volume, full bass etc. Never cut out other than that. For the price, you wont find more power.

Ive had this amp for about six months with no problems and it powers my 2 8" kicker comps pretty well. I have the amp turned up half way and it still gives me hard hitting bass.

Customer Testimonial

The guy on the phone did a great job answering my questions so I placed an order. They shipped my order out the next day and it got to Indy in a only a couple days. If I want to buy more electronics for my truck, I will definitely be using Sonic. Thanks for making my buying experience worthwhile!
