Damn! Every time I see those red bucket seats it makes me wish that I would have ordered the red interior! The only thing that made me chose black was that I didn't care for the red on the doors and around the lower dash. But I'm sure that probably could have been changed!
I don't think there is a third speaker on the package tray. But there are two 7 inch subwoofers. You can view a chart on the Pontiac site illustrating the locations of all ten speakers. I believe it was a link from the comforts/amenities list after scrolling down to the sound system. Pretty cool!!
