How did you cut the holes for speakers behind your seat?

[Jeff V.]

I would find it weird that any manufacturer would alter their panel dies just for a speaker cut out.

I agree with you. But there's a service diagram in the factory service manual. What finalfighter posted is legit. I can post the relevant scans of the pages if anyone is curious.

There's a lot of weird shit on these trucks that I think was done to satisfy Dodge. The optioned out Ram 50s are plenty rare enough, but finding that stuff on a Max is damn near impossible.
