Ok so i did a complete rewire of my audio system took out all the old bose and installed all new 6.5s all the way around, my question is this, on the rear deck with my new 6.5 does anyone know where to buy an adapter plate for the speaker? the bose speaker had a strange mounting pattern and im not too comfortable leaving onjly 2 screws in my speaker as it is not 100% sealed..

 

can u remove the BOSE mounting ring and use that. OR drill your own holes.

 

i did the same and added some infinity kappa speakers all around, the rear speakers fit pretty good in the stock whole from the previous bose system. if not, you can just drill a whole and use some screws to hold them in.

 

self tapping screws are your friend

 

When I did mine, my new speakers had the right holes, but they were just SLIGHTLY off...so I drilled the speaker basket, not the car... just enlarged the holes but about 1/16" and they all lined up...
