I put JL Audio 6" components in the rears. The tweeters are mounted up high right next to the glass. I just built a small ring that pushes the speaker out farther. Kind of the same principal that was used to put the 5 1/4 in the dash that Jim Clayton suggested. My problem wasn't the depth, it was the diameter of the speaker grill for the speakers that I was looking at, they were too big for the recessed area where the speaker goes.
Everything is kind of dusty I was out for a long drive the past few days and I was going through an area with a ton of construction

I left the pic big for detail
