Well, this is the first time I saw this post. What might be cool is the rear firewall cushion made out of carbon fiber and with an 8" speaker hole deep enough to mount a woofer into. Going from the limited space in the cars that might be a hot item. Maybe some spots for some 4" mids on the sides up by the seat belt too. I did that already on one of my old ones. It sounded good but that was back in the 80's. Shoot me an email and lets talk about it.
