Rear Right speaker not working

[Elitecoconut]

Hey everybody,

I am having an issue now were every time i open my door i hear the driver door and passenger rear speaker pop. The car only chimes through the cluster speaker now and not the ACM audio. I have checked the car with my diagnostic tool and it yielded me 2 codes B1A03:11 and B1A03:11-0A Speaker #3 short to ground. The passenger rear woofer and tweeter are just off now. I tired the sync full reset, the skip track and volume down reset, I just put a new updated Motorcraft BAG battery in the car Yesterday and did the battery reset. so far nothing has fixed the problem. My guess is that the woofer is blown and needs to be replaced. I did have the intermittent problem of the rear right speaker popping every time i adjusted the volume in the past, but it usually cleared it self after doing the am to carplay swap. I also tried messing with the surround and stereo setting and still nothing. I already replaced my center speaker as it has blown out as they usually do. The car is bone stock with no accident.

Some feed back will be great before I go blow money at the dealer ship.

I figured it out if anyone has a similar issue.

Turns out the harness that runs past the amp carrying the speaker outputs WAS RESTING ON THE AMP BRACKET. Over time the harness was slowly chafing until it cut a hole of the speaker ground insulation. It was grounding to the bracket as you can tell by the burn mark.

I patched the wire and shaved down the bracket where it made contact and that fixed it
