alright im porting my subs, and upgrading to a bigger amp. this thing will make 2 12"s **** like ghetto, with proper tuning it would be great on a smaller sub as well, ideally tho, great for 2 12s or a single 15". ive been running it on my 2 15s and its been fine, but at this point, its holding me back a bit. talk to anybody who has owned one of these or knows anything about them, old school JBL FTW! 1200 Watts RMS power running through a single channel, o snap! this thing is a pimp daddy amp for those with a budget. 180 bucks plus shipping will do the trick for me. if you live close to me, i can meet ya. im in palatine, il.
