hey there! new guy just checking in. I drive a Bonneville myself but my mother has a 2004 Gp Gt that has needed some stereo work recently and I've been lurking around some of the GP forums trying to figure it all out.
I figured I should check in so that when I have a question ya'll will know who the heck I am!
btw I hang out on pontiacbonnevilleclub.com and bonnevillepro.com come by sometime it's a pretty good wealth of 3800 info
