I recently had my battery replaced (3 weeks ago) so maybe it's related to a bad ground or something from what I read just browsing on the net but I'd like to ask if anyone here knows WTH this noise is.

I was listening to music at the same time (sd card in the car multimedia unit) and I think this loud buzzing noise came from the right side speaker or right side/passenger side of the car in general. I thought it might be from the sd card messing up so I lowered the volume but the buzzing alarm sound was the same and I could actually still hear the music playing in the background so it made me think it wasn't the sd card getting screwed up playing a bad file or something (like how CDs in the car used to make loud noises in the speakers when u have a bad file or a scratch on the cd).

Anybody have any clue where this awful noise came from? Never heard it ever in my life in all my years of driving lol.

I uploaded a short clip of it here on my spare youtube channel where I just use it to share video links for help.

It sounds like a shaman in an echo-chamber ...
Probably one of your speakers has a loose wire that's about to come undone. That's a really very weird noise but it's the only thing I could think of: microphonics.
Something does not jive at times between the head unit and the speakers.

could it have anything to do with the battery if there was a bad ground or something? Yes, it definitely sounds like it was coming from the passenger side speaker.

It could be, but if it is a bad ground then it definitely has to be one that's related to the audio/speakers circuit. Could also be a pinched wire that shorts on metal intermittently. It's the sort of diagnosing I'm guilty of failing its course...Maybe someone with electrical chops (knowledge) might guide you on this discovery journey.

Thanks! So far it has only happened once. Of course, I'm assuming this is audio/speaker related and not something else in the car that can make a loud digital buzzing alarm noise.
