I had a local shop do the system. I've known the guys for like 6 years now. Maybe more?
Anyway, they were the reason that I got hooked up with Arc Audio. They did a killer job and didn't mind how involved I got in the design and what not. Alot of times they will take an idea and run with it too, making the outcome that much better.
For those who are wondering, I measured the system a while back @ over 130dB all sealed up. I could get just shy of 140dB with the windows down a little and some minor tuning.
I jsut got the kick panels in today. They are a rgeat starting point for sure. I plan to add some deadener to reinforce them though. They will take a beating I'm sure of it.
