Hey guys...
So I just had the pleasure of experiencing this horrible screeching noise that started blasting out of my rear passenger side speaker (behind the head) when I unlock my car without turning it on. Key isn't inserted at all, the radio is completely off, and I don't have comfort access. When I unlocked the car, I heard this noise from outside and several yards away. It lasted about 30-45 seconds, and I caught just the tail end of it on a phone video.
I'm assuming my speaker is going.. Is that what it sounds like to you guys?
I just hit over 50K and didn't extend the warranty on the radio, just everything else. Damn it. It's like fucking clockwork, I swear.
