Ok. I'm new to this site and I'm a new Grand Prix owner.(Well I've had her for almost 5 months, so she's a lil new). She's a Silver 99 GT Coupe with almost 109k miles on her. I need to replace my old rear stock speakers because they are blown. They're 6x9s. I need help on how to replace them and remove the big speaker grill in the back. If anyone has done it or knows how to please let me know. Thanks!!!!
