i went out and check the sound, putting my ear to the speakers on both sides and they sounded fine to me. BTW, besides the Hansshow rearview mirror i don't have any other fancy gadgets installed.
Do like i did and put it in test mode to isolate the speakers i showed and take a video You might be hearing it from a different speaker, I was too until I did the service mode test. The front speakers confused me because I was hearing music from it.

I pointed this out a few months ago. Hansshow sent a new harness and the problem remains. And now my rear camera stopped working. This really is not a good product. I’m at the chuck it over the fence part of this install. I have video but it is too large to post.

The tweeter is in the A-pillar, it's the structure both in front of and behind the little window. B-pillar is between the doors.

Connector X0930 has the tweeter, full range, blind spot indicator, and microphone. The only unused pins are 4, 5, and 12. Everything else needs to be passed through.

Are those third party products pulling power from the A2B bus? Pins 6/7 or 13/14 with ground on 11?
I thought A started in front of the windshield, but whichever, you know where I mean. Do you have the wiring diagram for that connector? I don't know how many items they are or are not passing through, my blind spot indicator works on the passenger side, didn't test the microphone, I believe the full range speaker works, just not the tweeter, I tested everything on that side in the service menu and on the drivers side. I don't know which pins they are pulling power from because the cable that delivers power is about halfway between connectors and is wrapped in black material. I suspect they are just running the power pins/lines off to their accessory and didn't think about passing it through to the downstream connector at the other end of the cable bundle. Let me know if you want a closer look of some sort.

Which version of the Hansshow rearview mirror do you have? there are 3 generations, i have the latest one with the front camera built into the mirror, i hope it does not interfere with anything.
That is the version I have and you can see that in my install article, as others have said you need to run the speaker isolation test and you will see that your Hansshow cable is cutting off that speaker.

Have you contacted them since and told them the new harness they sent you was useless?

Go to service mode - the icon under the steering wheel is the audio test. Watch the video I posted, you can see which icons I've clicked to do the test.

Typical, I tagged them in this post, let's see if they reply. Keep us posted if you hear anything back from them.

@Hansshow Technology
I paid for a replacement wiring harness from Hansshow almost 3 weeks ago, never received tracking and still haven’t heard back from them.

I chatted with them on WhatsApp this evening and send them a link to my video and this topic thread so they certainly should be aware. I also just finished up my install video for the Hansshow LED Dash light strip with blind spot detection which mentions these power cable issues and the Blog article that publishes tomorrow will mention the issue as well.

Sure, I know what you mean, since there is only one set of tweeters, but if anyone tries looking them up it won't be listed under B pillar.
There are no power wires in the connector. Closest thing is the A2B bus which is combo power and data for the telematics and microphone.

Connector and schematics available here:
https://service.tesla.com/docs/Cybertruck/ElectricalReference/index.html

If you post photos of the ends of the connectors, I can do a visual check, but a continuity meter would be most useful.

Rear camera should not be related. It has two coaxial connectors and runs to the rear control module. But who knows with software...

Does the drivers side connector also not have power wires but the same A2B bus as the passenger side? The Hansshow LED Dash light strip ( ) has a secondary wire that plugs into the drivers side port that looks to be the visual equivalent of the passenger side port. I will get you some photos of the connector ends and I have a continuity meter in my toolbox somewhere... :)
