1st of all I thinfk your amp turn on is not connected so thats probably why you dont have sound out of thedoors. The amp is located above the right rear tire in the trunk behind the side panel to the right of the hinge assembly. As far as your problem with the lighting I think you have a blown fuse but I am not sure which one as I am without a schematic of your car at home. Work is a 30 min drive.Check out the fuses under the factory fuse box (there are screws that allow access underneath and there are in -line fuse holers underneath. Check out the connection behind the ashtray there is a possibility that the wire as it goes to the light on the astray light has broken off and this might cause the rest of the lights to go out.

Happy new year!
