Poor quality power.

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.

great product at great value

Have this amp hooked up to 3 JL audio 10s this amp makes these 10s work it hits hard. Had a competition with a buddy he had two 15s hooked up to a 750 watt amp and mine tied with him.

Good amp

It's a good amp if you just want a little more bang out of your subs, but it's not gonna be heard from a distance.

If your looking for a bang don't get this but if your looking for better bass this would be a good buy considering the price. It's still pretty loud.

pretty good

Product was installed into a bandpass enclosure. I don't recommend doing that. Specs said its ok but didnt perform to my expectations. I would like to have tried it in a different enclosure. It may have preformed better.

Awesome Amp

I would recommend this amp! I installed it for a friend of mine in the navy, I had his car. I hooked it up to a 12" Kicker Comp Subwoofer. It pumped that sub without a problem, I was VERY impressed!!

Pros: Amp Quality, Reliability, Design, Power

Cons: The wheel to select how hard you want it to thump didnt do much.

great amp

I bought one of these since i was on a budget to power a 10" Rockford, and it does that perfectly. Enough settings to dial it in just right and the bass control works good too. Ive recommended this amp to a friend who is now happily using it to power two kicker 8's. Never had a single problem and it dont seem to get real hot under my seat with not much airflow.
