Hey guys I've been working on my crx pretty hard lately and am getting ready to start on the interior. I am familiar with using molds and high density foam with hand laid fiberglass for exterior pieces but i have not made interior panels and sub boxes.
I would like to know a good process for making sub boxes- and the kind of material used... I heard a fabric is used to stretch over the frames rather than using the fiberglass mesh with resin.

For door panels- should a make a mold of the original and modify that... or is there an easier method?
-Thanks for any help
