The mounting depth for the sub is 4 11/16" and I used 3/4" mdf for the box and it was a tight fit. I also used 3/4" mdf for the speaker adapters for the doors. I just traced the factory
speakers to make some templetes and used longer bolts and nuts to secure them to the door. For the tweeters I had to make a bracket out of flat steel so they would bolt to the stock location. And yes I did have to cut some of the plastic from the storage compartments.
I forgot to take pictures of the doors before I put them back together. when I have time I'm going to pull off the door skins off and take pictures. Here is a link to some pictures of what the doors look like with the adapters installed.
