I was able to ID a couple of additional components today and have updated the 1st post. Additionally, I looked at numerous other amplifiers produced by HARMON. I confirmed they all have the unusual USB port, raising my hopes that it is for the DSP chip.
I’ve been updating the top post with some additional items. A thread I’m pulling on is the DSP. The amp has an undocumented access port which I believe is for the DSP and its configuration. The current challenge is the proprietary or odd ball connector. I think this connector is HARMONs way to...
@omiga I’ve cracked open the B and O amplifier. I’m not as knowledgeable as you on this but I’m hacking my way through it and could use your help. Check out my thread.
I bought a B&O amplifier from a wrecked convertible Mustang to learn more about what its hardware could support. I took these photos through a magnifying glass, so you will notice distortion along the edges. The blue stuff is a thermal paste that makes contact with the case, which is a massive...
@Evolvd, do you still have the B&O speakers lying around? I'd like to double-check the part numbers I recorded. My Mach 1 was built during peak COVID, and I'm starting to wonder if there was a part substitution for the rear 6.5 speakers.
After looking at what feels like hundreds of photos of wrecked Mustangs and their speakers, I can say that the B&O system has four unique speakers compared to other Mustang systems. I also have a B&O amplifier on the way to dissect.

Just trying to give back by rounding up all of the information I have on the B&O. Could I get some assistance filling in the missing details?

Can we get you a B&O amplifier to reverse engineer? I was hoping somebody would come along and take it apart. I've attached the B&O "12" speaker wiring diagram for reference.
I'm not sure if you're still on the forums, but I wanted to thank you for your video. Part one is the most comprehensive interior teardown video I've found.
Find a new dealership, and call around before you do. I brought my Mach 1 in for transmission TSB-24-2101. The dealership had it out of their shop in 2 weeks with a new valve body. If the harsh 4-5 shifting continues, full transmission replacement is next. Seeing how your transmission grenade...
Update: seems to be 90% better in normal mode. Sport mode 4-5 shifts so hard that I'm concerned it's ripping the transmission mount. I will give it another 100 miles or so before making an appointment again.
