Pushes Hard!

Very highly recommended! Inexpensive, compact, stays fairly cool, and plays very loud. Had it wired to a pioneer 12 2000W DVC sub @ 2ohms.. Ended up cooking the sub! I think the amp pushes a little more than the 1200W @ 4ohms/600W @ 2ohms. I took mine apart and painted the black part with a nice automotive blue to match my car. Looks very sharp, plays super hard. Currently running X2 1400W Pioneer 12's @ 2ohms, hits insane hard!

Does it's job and stays cool doing it

I have this amp running at 2 ohm pushing a JL 10W3v3-2 in a JL stealth box and it does its job well, shakes, rattles and rolls my truck and sounds super clean compared to the alpine V12 amp it replaced. Amp stays nice and cool and doesn't miss a beat.

Great amp

I have this amp hooked up too 2 rockford punch stage 3 they hit hard clean and precise it is a great amp also the small size makes it easier to mount. the bass boost works great to originally i had it hooked to 2 pioneer 12 inch 303r's they seized in about a week and a half think this amp is a little under rated so make sure your subs can handle the power which it does put out well. the punches have survived 2 months so far and after the break in have worked perfectly with the amp
