my sub is made into my spare tire space, I used 2x2 and made a frame then glued it down around the spare tire space with liquid nail... let it cure for 24 hrs. then filled the gaps with expanding foam (dries in 4 hours), the only place I didn't seal off was a small slot so icould use that area kinda like a slotted enclosure would... then I made a baffle the size of my hatch area and cut a 12" hole in it for my sub and carpeted it... with a normal 12" enclosure it sounded good, a normal 12" slotted sound a little better, but this way hits pretty damn hard... and I am proud of myself for it...

no engine work yet... just a stock LS w/gsr tranny...

thanks for the comments...
