Speaker mounting depth

In the process of piecing together somethings for an audio build in my '12 dcab, and ran into the issue of finding the right speaker depth restrictions on these trucks. I remember in my 07 ACab I had 3" to play with maybe slightly more.

I have no idea how much I can get away with in this truck both front and rear, anyone have any ideas. Sidenote, yes any speaker will have a 3/4" MDF baffle before it gets put in the door, maybe 1" if i can get away w/ it not hitting the back of the door panel

Thanks, Hank
