Ive had this amp for a little over 2 weeks hooked up to 12 kicker ds650 and it has given me so many problems. It overheats after about 3-5 minutes of use and shuts off sound. Also it smokes a lot. Idk whether i received a bad amp or something but plz don't waste your money on this amp

There was no way this thing was putting out the power it said it was. And it didn't. Switched it out with another amp that was 125x2 and it blew the crunch out of the water. No sound quality or power. I bought it for $125 also. I hate the knobs too. Very cheap plastic and not thought out too well.

Customer Testimonial

I tried to purchase an item from another online store, wrong answer! Sonic Electronix is a great seller. Not only is their customer service great, but their shipping is better. Completely satisfied with my product. I will not shop anywhere else online when it comes to car audio. Thanks.
