2021 B&O Unleashed Overhaul Question

[Brewha1324]

Looking at overhauling the entire B&O unleashed system in my 2021 F150 SuperCrew. Unfortunately though, it will be done in phases. The first phase will be a Sub/Front Stage overhaul and the second phase will be rear/accent speakers. For the first phase, I'm seeing that the rear speakers and tweeters are run from the Front Audio Control Module rather than the DSP. Is this in the same location in the rear of the truck? Would anybody be able to tell me where the FACM is? Is that the main head unit? Eventually I'll be using a NavTV A2B, but that will be for phase 2. so I'd like to find full front stage outputs somewhere in the rear of the truck. Here's what will be hooked up in stage 1:

2 10" Hertz Mille MP250 D4.3 in Custom Fox Acoustics Box
Audison AP 4.3 Bit for Front Stage/Sub Line Out
Audison AP F1D for Sub Power
Front Woofers - Hertz Mille MP165.3 Pro 6.5" Actively Driven
Passively Driven Mid/High:
Front Mids (L and R Instrument Panel Pods) - Hertz Mille MP70.3 Pro 3"
Front Tweets - Hertz Mille MP25.3 Pro
Passive Crossover for Mids/Tweets - Hertz Mille MPCS 2 TM.3 Pro

Thanks for the help!
