Sub box design

I've seen a few different designs i like but I want to see more if people have them:







I kind of like the last one but it takes away the whole pass through area. Any other kind of boxes people have seen or built that wouldn't mind throwing up pictures so I can get an idea of what I'd like to build?

im not too sure of the specs but this box and subs THUMPS in my GP. The pic u posted will more than likely sound like shyt. like u said the whole pass area is blocked.

yea but from the looks of it you dont have a functioning trunk...and the other design saves alot of space...i have seen somewhere a guy made a dual enclosure that allowed the pass thru and was neatly made...but i have no idea where i even saw it

theres this design...Grand Prix Sub Box

and this design is super nice 1999 Pontiac Grand Prix Custom Installation

that's a really nice and clean box right there.

I wish I could create a fiberglass enclosure but I don't have those skills. This whole project will get put off for a while anyways as my HU was stolen this weekend. I need to just get my car audio back in place lol.
