I wan't to change the rear speaker, but had no idea hot to take the panel appart. So I unscrewed the two screws behind the seat, and when I tried to pull it, I might have broken two pieces of plastic that holds the panel cause now when I put it back, its not tight. But then I checked the speakers, and they had no screws. They look like they are permanently factory sealed. Does anybody know of a place that shows me how to remove the panel ( I don't want to f up the other panel, and remove the speakers and replace them?
