2025 Bronco B&O Architecture – ACM vs. AMP/DSP Wiring Discrepancy

[josephc04]

Hey everyone,

I just got my hands on the wiring diagrams for the 2025 Bronco B&O audio system, but the speaker routing has me genuinely stumped.

According to the ACM diagram, the ACM directly feeds the front kick panel speakers, which then jump over to feed the left and right dash speakers—essentially identical to the base audio setup.

However, the AMP/DSP diagram contradicts this, showing that all speakers are fed directly from the factory amplifier/DSP.

Is anyone familiar enough with the refreshed B&O architecture to explain how these are actually wired in reality?

I’ve attached both wiring diagrams for reference. Thanks in advance for the help!

It probably depends on the Bronco, the market, the build date, etc.

Every 2025+ Bronco I've seen feeds their speakers entirely from the DSP.

I don't think the wiring diagrams you have are for the Bronco. In PTS, the 2023 Bronco only shows a 6/7 speaker system or a 10 speaker. The diagrams you have are for a 12 speaker system. See attached.
