Beaub46 Posted April 30 Report Share Posted April 30 The wife as a 2021 edge st-line and talks about a sub. I was wondering if the oem B&O subwoofer would be plug and play in a st-line? If anyone would have info would be really appreciated! Quote Link to comment Share on other sites More sharing options...
Haz Posted April 30 Report Share Posted April 30 (edited) Welcome to the Forum, @Beaub46! So, as you're aware, the 12-speaker Bang & Olufsen (B&O) sound system was only offered on the 2021 Edge Titanium... The 2021 Edge Workshop Manual describes the operational differences of the 6-speaker sound system in your ST-Line Edge and the 12-speaker B&O sound system... Placing your device cursor over underlined acronyms may produce full-words descriptions of the acronyms. DSP The DSP is a power amplifier for the vehicle speakers. The audio input signal comes from the ACM via the Automobile Audio Bus (A2B) cable (North America). ACM Speaker Output - 6 Speaker System The ACM is configured to directly power vehicle speakers. An amplifier in the final stage of the ACM sends an analog AC signal to drive the speakers. Output may include stereo and center channels. The ACM powers all of the vehicle speakers. A speaker circuit short to ground or power can be detected by the ACM . The ACM may disable speakers to prevent damage to the internal amplifier. A DTC sets to identify which speaker circuits are causing the concern. ACM Signal/Speaker Output - 12 Speaker System (North America) The ACM is configured to directly power the front door tweeter speakers and all of the rear door speakers. An amplifier in the final stage of the ACM sends an analog AC signal to drive the speakers. The ACM outputs audio data over an Automobile Audio Bus (A2B) cable to the DSP . The DSP powers the remaining vehicle speakers. A speaker circuit short to ground or power can be detected by the ACM and the DSP . The ACM and the DSP may disable speakers to prevent damage to the internal amplifier. A DTC sets to identify which speaker circuits are causing the concern. Differences are also evident in the 6-speaker and 12-speaker Sound System wiring diagrams... 2021 Edge Audio Sound System - 6-Speaker Wiring Diagram 2021 Edge Audio Sound System - 12-Speaker Wiring Diagram. Page 1 2021 Edge Audio Sound System - 12-Speaker Wiring Diagram. Page 2 2021 Edge Audio Sound System - 12-Speaker Wiring Diagram. Page 3 2021 Edge Audio Sound System - 12-Speaker Wiring Diagram. Page 4 And finally, getting to your question: Because of differences in the ST-Line's standard 6-speaker versus B&O 12-speaker Audio Control Modules (ACM), the absence of an Audio Digital Signal Processing (DSP) Module, and the B&O Sound System's more extensive 12-speaker wiring, the B&O Sound System's Subwoofer is NOT Plug and Play in your 2021 ST-Line Edge. Having said all this, numerous Forum members have added aftermarket subwoofers to their Edges. Clicking on this link will direct you to subwoofer discussions by experienced Forum members. Good luck!

bw228 Posted June 14 Report Share Posted June 14 Do you have a layout/location of the ANC microphones? The pics above from the workshop manual are super helpful. Quote Link to comment Share on other sites More sharing options...

bw228 Posted June 14 Report Share Posted June 14 THAT is amazing! One more thing and I'll leave you alone lol Is there any way to verify that a 21 ST has the exhaust note piped in to the audio system? I've seen yes and no in my searches and when I've seen yes, there hasn't been a way to defeat it. Quote Link to comment Share on other sites More sharing options...

An amplifier in the final stage of the ACM sends an analog AC signal to drive the speakers. Regarding your interest in a true switched power source, perhaps the AM/FM Antenna Amplifier power circuit can provide you what you're seeking, since I expect the antenna amplifier would only be powered when the audio system is operating.
