I have not found anything in the search but was just curious if anyone has thought about pulling the back door interior panel off and creating a custom panel for their amps and maybe a sub or two? I have 2 reasons for this: 1. to keep from taking up too much cargo space as I actually use it for household work and 2. I think it would look nice to get my mid and sub amp in there with a shallow mount 10 or 12 inch sub. Fiberglass and mdf seem like they would get pretty heavy but I think the door hinge could handle the extra weight. Just looking for any inputs or to see if someone has seen this done on the FJ before.
