Ok everyone i have built a custom fiberglass box that takes the place of my back seat. I covered it in foam and then black vinyl. After i covered it i put my 12" l7 in there and then tested it out and i blew up the back of the box. Does anyone have suggestions on my next box, how think should the fleece be and how many layers.

Just so I know, you only used fleece? Use several layers of chop matt and cloth. Fleece and resin is brittle and should be used only as a form.
If you can't stand on the enclosure without it buckling, keep building it up.
I saw pics of an enclosure for an F-Body that was used as a jackstand for a Corsica to illustrate just how strong it was, so it is possible.

post them on a site like photobucket.com, and then link the images from there (it's a button on the top of the reply text box that shows an arrow pointing to the top of a picture with a mountain in it)
so it just blew out that little hole??
