For the price you CANNOT beat the amp. Sure there are other amps out there in the "1000x1" class that will beat this amp none for this price. Running this amp on 2 12" DVC Rockord P3 Subwoofers which are 500rms each in a 4.45 cu ft box tuned to 37hz. all pushed at 1ohm. I beat the hell out of these subs and the amp is just luke warm!
First off, let say that if you are not happy with your sub and amp, first check your box! TOTAL world of difference to have a box built to size specs for the subs not to mention switch from sealed to ported enclosure. amazing My amp birthsheet stated 1334 RMS watts. INSANE. If I ever swap out my subs and get 2 12's that are 1000 rms each, I will definately buy another 1000bd.
