Did you make it any further on your project?
Also, I see you left your window up but it seems like most pics I see of this process they have the window down. Is there a reason to do one over the other?
Here is an album with all the other pics I took. The further I got into it, the less pics I took, but ultimately it all turned out as expected and everything worked great.
Regarding the windows, if you are just changing the speakers it won't make a difference. You need to disconnect the window and raise it up out of the way to get to the inner door skins for sound deadening. You can see in my photos some of the inner door skin before and after applying the sound deadening.
You can also see in some of the photos the MDF board I added is where the amps ended up getting mounted. Ran the signal down the driver's side and the main power down the passenger side. Both fit into the factory wire tracks in the front and rear door sills.
I started out with the small sealed box, which was originally installed in my 2014 Ram. In the old truck it fit perfectly between the center console and rear seat. In the new truck, not so much.
I stumbled into a deal over the weekend for a W7 specific vented box that is bigger, but fits a little better and allows the rear seat to fold down.
Long term, I will probably end up going with something built to go under the rear seats, but for now this is working for me.
Let me know if anyone has any questions.
Thanks!
