I have this amp pushing two Sony Xplod XS-GTX120LW 12" Subwoofers. They sound great and hit hard. I listen to mostly country so there's a lot of bass drum coming through. This amp does a great job and gets a little warm but I have it in the trunk where's there's a lot of air flow. I recommend this amp for anyone wanting a good price and good quality.

I have had this amp for about 6 months now, i originally had it powering 2 10" MTX terminators at 150W RMS each, the amp did great with very little clipping with theese speakers, about 50% gain. I had since upgraded my subs to 2 10: Precision Power A.10 with the plan to upgrade my amplifier in the new year, i powered them up with this amp, wired at the same 2ohms as the MTX subs, with about 75% gain, sounded great for the first month, but into the second month the amp began to wear out and clipping occured at that gain level. I turned the gain down to 50% again and it kept clipping, well now i have $200 worth of subs with blown voice coils, I will not buy another boss product and will be ordering a Hifonics Brutus 1200.1d to replace this.



use this with low powered subs and you'll be fine. Definately not a quality amp though.
