hi,
my dad has a 73 mach 1 mustang... the speaker panel in the back is shot, its a cardboard like material that has warped over the years. i thought it would look really cool to make a custom speaker panel by making a wooden template for where the speakers go. then covering it with a felt like i saw on the 702 motors show, then applying resin to make the felt hard, and using bondo and fiberglass hairy things to fill in gaps.

yes i practically just explained how to do it, but i really didnt. i dont know what to do and how to do this, i would appreciate it if someone could direct me to a site that could give me this info, like what materials to use, or how i get the speakers in the paned after i finished the bondo work.

please help, if you know any info please feel free to share.
