While I was thinking a setup in my head, I hit a bump. When you build your box with fiberglass, how do you match/connect wood with fiberglass? Do you just fiberglass over the mdf boards? Do I need to do anything tricky to join them strongly? If you have detailed pics of how you mated the wood with fiberglass, that would be great! Because I'm thinking about put 2 10s in the trunk, so I was going to mount the subs to a board and use fiberglass for everywhere else. I was just thinking about putting few layers on top of the board, but wasn't sure if it will be strong enough. I just want a solid/leak free box. Any ideas?
