[QUOTE="hispls, post: 8715205, member: 614752"] Fiberglass is going to be expensive to build up thick enough to be very rigid and it is a PITA to work with. I'd suggest trying your hand with some smaller fiberglass projects (like midrange pods) before you go all in building a subwoofer box with it. 12w7 would do well up to about 3 cube and it will want 32-34hz tuning. Dunno how you'd fit any adequate diameter port in a spare tire well though. IF you want to "port through ski hole" type thing you should look into a 4th order bandpass box which may work well for you but definitely would be impractical to build out of fiberglass. [/QUOTE]
