I noticed nobody's mentioned it, but a few years ago while searching for a new system for my car, I was approached by a salesman about Concept Audio. Like most of us, I was critical, and I was going to stick to the big names. After 3500 dollars (Canadian) and a few hours of waiting, my 95 GT emerged as a competition winner and I've never been so happy. 3 years later, running a total of 10 speakers and 5 amps, all in place of old Mach460 setup, with a few extra subs, and a self amplified Sony head unit, I'm still making other cars loaded with more expensive subwoofers look pathetic at Audio shows. Inside the car I'm only throwing out 138 decibals, (in comparison, that matches my exhaust from 8 feet back in a parking lot....my car is uber loud), but that's more than enough to make a small street party, and yet I haven't yet even changed my alternator. Try Concept, you won't be disappointed.
