I have been doing a lot up stereo upgrades in my sc and I have have found some very sweet ways of adding great sound cosmetically. Your best bet is to have kick panels made from fiberglass and mdf. I was quoted 225 a kick panel at the best stereo shop in town, but you can probably find cheaper. Anyways, they can fit any size speaker, coax or component, and they match the carpet, so this is the best bet on the cosmetic route. The doors would be too costly and look unnatural in such a beautiful car. Good luck. Let me know what happens!
