I have a rockfrod fosgate t1000bd the older one that claims 1000 rms at 1 ohm but defantly is under rated i have two type r 12s going to it at 1 ohm and i have it half up and they bump i am jsut going to go with a Fi q 12 and a aq1200d and run it at 1 ohm. also this amp is jsut to big to fit in my truck comfortably. It has some cosmetic scarpes and stuff and needs a new speaker wire input but it works fantastically and well worth the effort to fix has more power than i know what to do with. im selling for 200$ just because of the cosmetics but im pretty sure it has all new internal parts i think it was rebult by my buddy who sold it to me.
