^^ yeah, I chose 12 because I have a 12" punch laying around. Its optimum @ 1.25 ft3 sealed, so I think I can build it out enough to eek by. If it sounds crappy, I'll start over with a pair of shallow 10s. How hard is it to work with carbon btw? It's expensive and I don't have access to a vaccuum so I've stayed away.

Not a very exciting day ;p
Took the piece out, removed the masking and did a test fit. Some tape left over that will be sanded out at the end. The glass will be transparent and brittle at this point (unless you put multiple layers on at the start), so be careful.
Applied two layers of heavy weave + two layers of chop to smooth it out. Let it dry overnight and test for strength tomorrow.
