Re: Question about Prem Sound Sys in a 2006 GCL
Mine didn't have the things on the door panel either. You can look through the vent in your drivers side rear quarter panel siding. With a flashlight you should be able to see the amp, or you can take off your dash speaker grille. If the speaker is Boston it should be the Boston system unless some one swapped speaker. Your post sounds like you purchased it new so I'd doubt that.
