as for t-tops, i have a sawzall and i love to cut sheetmetal with it. i can hook you up.

sorry flim flam i will now chime in with intelligible comments.

like illegal said, any car audio guy should be able to do it. i know ive built amp racks and sub boxes out of mdf that people wanted to have "secret compartments" in to keep "stuff". check with your local car audio custom shop, im sure they could build a nice looking carpeted setup similar to what mighty mouse posted. probably wouldnt cost a terrible amount of money either
