Rear windshield has a foam that’s touches the glass from the rear sun shade assembly. So far I tinted it and have it curled against the foam. The foam is right at the edge of the dot matrix. Hopefully it can dry like that and I’ll leave it be. As for stock amp in the quarter panel I didn’t see any but I looked and saw that Audi engineers put a plastic cover to protect electronics from water. Be liberal with your slip on this one. I’ll report back on how it goes tomorrow when I finish
