Customer Testimonial

I live in Canada and was surprised by the fast shipping! I live far away from any large cities and it only took a week to deliver. The customer support was great, Kirk C. gave me a rebate. Sonic Electronix is an amazing site and I will continue to shop here.

This was a very good decision on my part! I really recommend this amp. I can honestly tell you that I had my doubts about buying his item online, but after six months of ownership I feel like a smart shopper!
