I installed the Polk Audio db6501 component speakers in the front doors. It took me some time to figure out how to mount the tweeters and crossovers.
The Db switch on the crossover is accessable from underneath by popping off the lower part of the door panel and using a thin flat bladed screwdiver.


Aluminum mounting bracket for the Polk tweeters.


Surface mounting cup that came with the Polk tweeters I'm using stainless steel machine screws..


Right hand side, same layout as the drivers door.


This shows how much foam needs to be removed to clear the cross over.


To mount the crossover, I used a piece of aluminum that I drilled so I could use the factory screws.
