Look in the front trunk behind the spare tire. There is likely to be an amp there. If you need to replace it, let me know. The problem could have several sources - defective head unit, defective amp, or severed or disconnected wiring.
I haven't run into the problem with the window, so I hope that someone else will suggest the source of the problem.
Nice car by the way. I like the look of the factory litronics.
