I need a recomendation on a wall size for 2 mayhem 18s in the back seat of a 2002 grand prix 4door. I've been told between 6-8 cub. a piece, but I don't know if I honestly have room for 12-16 cubic feet. I was considering just running 1, but 2 is what I want to run the most.
Any ideas or recomendations on what to build it to and what port size?
