Finally finished my complete upgrade from the Bose system. I noticed that the Focal grills on the door speaker would not fit as the door panel is curved. Also the grills for the rear speakers seem to be glued in place. As the speakers themselves are attached to a second panel about a inch and a half below the rear shelf I couldn't install the Focal grills there either. Aside from the single DIN radio the only visable pieces are the two red Focal 400w amps attached to the back (trunk side) of the rear seat. Kinda dissapointing.

 

you dont need to install the grills.

the door panel acts as a grill

otherwise you door would bulge out

 

Due to the design of the Focal speakers I used for the door location, I had to install 1" thick spacers for them to fit. This resulted in the door panel becoming curved. The stock grills were adapted to fit as the Focal grills would not work.
