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.

This sub works great. Previously, my '02 LeSabre had nice sound with a Clarion head unit driving Sony ExPlode speakers in the door and back. I purchased this sub, an enclosure with a Jensen amp recommended by the excellent phone hostess. Within a week I had it professionally installed and I tuned the bass to fill in what was missing. It provides oomph and subtle warmth. when cranked, it performs admirably without cracking. A track on Neil Young's Lenoise album literally rattles my teeth. I highly recommend this sub and the matching Jensen amp.
