i just got my subs into my 01 s4 and now the window shade that rolls up and down in the rear window rattles like crazy and seems like its gonna break my window when it hits the corners. does anyone know an easy way to get ride of that problem? i stuck velcro on the part that you pull out and stuck it to the permanent pieceto make it not rattle but i still don't like the whole piece in general hitting the window. i called a dealer and they said its like a 3 hour process to take it out. any idears?
