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.

This amplifier has definitely held up to expectations. It has a lot of power. I have it running into a 175w RMS 300w peak 12" subwoofer. I haven't had a single issue with it. It's worth the try/buy.

I have owned this amp for about 6 months now, and it just cut out. I had my sub wired for two ohms which the sub can handle. It couldnt and would overheat. I rewired my sub to 4 ohms and now it sounds better. For the price its an okay amp. But for a little bit more you should probably just go with something a little more reliable.

It's alright. Installation was easy. So far, (about 3 months later) it seems pretty durable, doesn't get hot. The bass knob is useless, i wouldn't recommend even installing it. Just use the sub controls on your deck. I have it pushing a kicker shallow mount 4 ohms rated at 400rms and this just doesn't push it like i feel it could be pushed. Will upgrade at a later date. Probly with a higher quality amp. Overall, you get what you pay for. Kudos to Sonic though. Their customer service, and shipping are first class. Have ordered several items and their shipping is always prompt.

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.
