Driver side speaker 'buzz' - 2025 B&O

[MaximuNashville]

Hi all - back in a bronco after a crazy several months of musical cars (Everglades to 4Runner to Land Cruiser Premium to Land Cruiser First Edition to Tesla Model 3 to Badlands). Good timing because I just attended my off-rodeo for my 24 Everglades purchase in TN this last weekend.

Anyway, I've had my 25 Badlands for a couple weeks now and have been battling an issue that keeps getting worse and worse. I noticed on the drive home from the dealer and thought it was something with the accelerator pedal as the rattling/buzz/nonsense only happened when applying throttle. A couple weeks later and I noticed it starting to happen with normal audio as well. Interestingly, it does not do it when using cruise control. So after some redirected investigation, I can confidently say it's the driver side kick speaker. My guess is that the throttle is causing fake engine noise to be pumped in, which is then just triggering the speaker issue. It's the 25 B&O system for what that's worth. Speaker is reading 2 ohms so I am pretty sure it's not totally blown. The issue happens more often recently, but not 100% of the time (let's call it 90%).

I tried searching but nothing specific to this came back. I have an appt with my local dealer Friday but wanted to see if anyone has an easy fix?

Sounds like a grounding issue... swap out speakers from left to right and see if it persists....at least that way you can determine if it's the speaker itself.

Does it change at all if you play certain music or adjust the volume - or just throttle without cruise control?

Ah, this sounds like a great way to triage. I will definitely give this a go tomorrow!

Great question, I’ll try some different music types tomorrow. I had a 3+ hour drive home from the dealer and was listening to an audio book so didn’t notice the audio triggers - really thought it was the pedal assembly for about a week.

Folks have had the pedal assembly rattle, so that's a possibility

Mainly trying to help you point out if it's an electrical sound being reproduced by the speaker - ground loops were common for this back in the day but it would be very unlikely from an OEM system -- or a mechanical issue, like a rattling piece of trim or a loose bolt someplace -- or something with the driveline, like tire noise or a CV whining
