Hey

It is possible to fit 6 1/2's" component speaker set in the front door of my 01 A4 ? Give me good advice.

 

well i fit 6 1/2's on the rear doors which said only fit 5 1/4's. I used the factory bose speacker bracket and cut of factory dowel pins that slipped on the bose frame. Not too hard. Then I positioned the 6 1/2 in it and redrilled new holes. It worked fine just make sure theirs room for a bigger magnet and it clears the window regulator and glass. The front should be about the same, think a little about it and take your time.
