I did not find any information about the AMP of this vehicle in Raise's public information.
Under normal circumstances, after the CANBUS works, the AMP will also start. But the AMP settings you adjusted in the vehicle settings will not take effect. This situation only occurs on vehicles without AMP.
This phenomenon is difficult to explain.

dudu-lai Thanks for your responses. I have uploaded several photos and a video to my Google Drive for you to view. Just go to the link below.

Question: Should I have removed the stock ACM (Audio Control Module) that sits above the stock SYNC 3 screen or is this needed to continue powering the amp and speakers? There is a plug going to the ACM that fits into the main DUDU7 harness that has the 12v, ACC, speaker wires, etc so I assumed I needed to use that and remove the ACM but now I'm wondering if that is my issue! If I need to keep the ACM, how do I properly wire it in? Thank you!

80adid It must be removed and connected to DUDU, otherwise where does DUDU get its electricity?

80adid

Yes, leaving the ACM in was a suggestion from someone else but it didn't work. I still can't figure this out.

This is the audio output. Do you have any other Android radio device? You can try it.

80adid

I can confirm that the stock SYNC3 stereo still works if I plug it back in but I don't have another Android stereo to test. I'm aware that these are the speaker wires but are they pinned incorrectly maybe?

80adid Audio is only on connector A. What do you think is wrong?

80adid

I don't know what's wrong but I still cannot get it to play through the speakers.

dudu-lai

80adid You can try to use the wiring harness and CANBUS box that retains the SYNC head unit to see if that solves the sound problem.

dudu-lai Has there been any confirmed cases of the DUDU7 being installed into a Ford vehicle that has the SONY sound system? I've been working on this for over a week now and still have the same issue and no one seems to have a solution.

80adid

Can you explain what you mean and how I would do that?

This connector is for the AMP control cable, do you have the connection?

80adid

dudu-lai Which pin is it supposed to go into in that connector?

80adid

dudu-lai Are you saying that the red wire is AMP control cable or that the blue AMP wire in the other connector is actually meant to go in the connector with the red wire? It is my understanding that the red wire is ACC. Please clarify and if possible, please be more descriptive/specific.

80adid Connect with original F connector

80adid

I'm sorry but I don't understand what you're telling me to do here. Connect what with the original F connector? Are you asking me to confirm whether the amp is functional with SYNC re-installed or are you saying that I have the AMP control wire connected wrong? I don't know what you're saying but I have been working on this for weeks and still have gotten nowhere beyond where I was at when I first connected and powered it on.

dudu-lai

Sorry, that's what I meant, the connectors in the picture need to be connected together

80adid

dudu-lai That is already how it's connected. If you look closely in the photograph you can see the original F connector wires coming from the other side.

Do you know of what else the problem could be?

dudu-lai

80adid I consulted with the CANBUS bus box company and they have not encountered this either.
Typically, the cable from the F connector needs to be connected to the AMP-C cable from the A connector of the DUDU unit for the stock AMP to work.
The CANBUS box company would like you to provide a photo of the OEM screen and the OEM mainframe back connector. Are you able to provide them?
Photos like this one

dudu-lai

When connecting to the original main unit, plugging in all the connectors and unplugging the F connector, does it also appear that there is no sound?
