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.

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

You folks have made a customer for life. Steven with customer service got back to me ASAP with a new arrival date. Thanks again!
