I have a 2022 Ram 1500 w/ the 10 speaker alpine system as well, but I do have the ANC module under my seat from what I've seen.
This is exactly what I'm trying to figure out as well. I want to tap into 2 of these wires (if possible) for signal to LC2i pro so I can get that low input voltage signal to my aftermarket amplifier. Have you discovered anything or found out new information since starting this thread? I have the ANC module under my drivers seat so I can easily bypass that with a harness like LLJ customs Jeep | Dodge | RAM ANC bypass harness 2018-2023, but I have yet to find where the factory alpine amplifier is located.
The most I've found from research and forums is it's possible that 2/6 of those wires may be connected to the ANC system. Which it's not common to see a triple voice coil subwoofer thus my confusion with the whole situation. Supposedly, each voice coil has a 2.2 ohm load, so I have yet to really find a definitive answer.
Then another individual stated that 4/6 of those wires were used for "upper door speakers" in the harman kardon system, and Ram instead of removing them just created an application (subwoofer) were the original wiring could be used between either premium system.
Hopefully this helps and we can figure something out or at least gain more knowledge.
