Hey all, I'm in the works of planning to make a sub box for my sedan that will go in the trunk in the right corner closest to the tail-lights where there seems to be a lot of un-used space. Anyone ever make one of these fiberglass boxes and if so any suggests or tips before I get started?

Side-note: I've seen the jack-box adaptation, put I'm looking to put in a 12in sub and not an 8 or 10, hence why I'm trying to use the bigger and opposite corner.

Lots of planning and patience. Also, try to do the work when the weather is warmer and dry...cold weather and moisture will make the process take a lot longer than it needs to.

I've only done one and it yes it does take a lot of time. I made my box go in the spare tire well. Check out my pics to see how it looks. Only advise that I know of is try and make a mold from something first.

Saw your pics. How much dynamat did you use to do your whole trunk area?
