I have a M8200 with a cab. I think it's about a 2000 or 99 year model. The speakers have never been replaced. I tried to remove the speakers today but cant get the screws to come out. They just spin and spin. I looked it up and it says its because there is a nut of the back side of the headliner that has come loose. Is there anyway to get these out without removing the top of the cab?
