Customer Testimonial

Sonic was very patient with all of my questions about installing and purchasing products. I took more time then most people would. Not once did Mr Brendan H. give me any negative feedback. I would highly recommend both Mr H and Sonic Electronix.

Deep, heart pounding bass out of a little 8" sub? That's what the MB Quart RLP204 delivers. Used it to replace a factory sub in my GMC Yukon XL and it blows it away even with the stock radio.
