I need pics of installs in the trunks of 80s model Chevy Caprices and Cadillac Fleetwoods. I still can't figure out how to begin a blow-through with my 15, and I need some pointers. It has a funky azz hump right behind the seat that keeps me from just sliding my box up to the seat flush, and sealing around it. Its frustrating the hell out of me, so I need some help.
