That's all i've come up with so far. It's going to be pretty expensive, but my main concern is powering it all. My car has trouble powering just the 8inchers so I figure this will probably be impossible. I already have a optima battery, what alternator should I upgrade too? Also what should I look into for reasons why my car has charging problems (any tips or tricks/common things). My dad's 5.0 charges much better than mine.
Also can anyone rec. a good speaker/amp setup for the front 6 speakers?

I can't wait to finish this project. Give me your opinions.

Thanks for the link John. I've been thinking about something like that ever since i've seen your car. Ill give ya a ring when its time for that. Can you do fiberglass also?
