I have actually made some custom speaker panels for customers cars, (a cabinetmaker/carpenter by trade with a pretty complete shop, I find retro fits like this pretty easy to do when it comes to the structural part. The problem here is that these rear side panels are carpeted to match the rest of the car, so I'd have to be able to find carpet that matches. Upholstery is not my strong suit either, as you can tell. I'd like to keep the money and put the headliner in myself BUT I see that as a move frought with complications.

I promise to take my time and think this process over before I do anything You'll be sorry for.
