Fiberglass boxes

[3.0ranger1227]

Anyone built speaker/sub boxes using the vacuum bag technique of fiberglassing? I.E. building a plug(undersized for the part), release agent over that, lay up the glass, bag over everything and suck it down tight, let cure?

thinking about doing it for my friend's 350z instead of building a wood box(gonna need some serious curves to make look good, which is going to be hard with wood. I'm thinking that I can melt the plug out of it through the sub holes.

I'm also thinking wood backing for the amp and wood rings for the subs, both probably 1/2" Marine plywood. Anyone see any issues here?

attached is what we're thinking for the box, probably with smaller subs though lol(sorry for the bad photochop)

No trying to do it that way is making alot more work for yourself. Easyest way is make a frame out of 3/4 mdf and wooden dowls and your rings streatch fleace then glass the back to make it strong heres a few pics of the last one i did
