My right side door speaker cuts in and out when I hit a bump. I've checked all the wires in the trunk and they feel tight. I think I have a loose connection at the speaker. I've read a few threads and some say you can remove the speaker without taking the door panel off. I've tried to take the speaker grill off but I'm afraid of using too much force. Any tips on how to get the grill off and if I do can I pull the speaker out from there and check the connections?
