Just some final notes on the installation process for anyone else looking to do the same...
Removing the front screen panel of the truck to installing the PAC AmpPRO SUB module was fairly easy, and I feel much better knowing I have a flat signal going to the subs that isn't controlled by the Ram's EQ settings.
The ANC is bypassed using PAC's APH-CH03 harness, even though Crutchfield says it doesn't fit in my specific model Ram ('19 with 12" screen and Alpine system). This is also the harness to use if you want to power the factory speakers with an aftermarket amplifier, or if you want to pull speaker-level signals to your amp's inputs.
I ran all my wiring down the driver's side. It's not optimal to have power and signal wires running parallel for these lengths, but with shielded RCAs I hope this won't give me any problems.
I used a factory ground stud that is attached to the bottom of the cab behind the passenger seats for my amp. You'll have to pull the back wall carpet out of the way a little bit to get to it. Yay for not having to sand away paint or drill any holes!
I'm happy with the install and the Stealthbox (after fixing the out of phase wiring configuration that the box arrived with!)
The APH-CH03 is the one that fits our trucks with the Alpine and is the proper one to use to redirect the speaker wires to your aftermarket amp.
