Constant whining-buzzing noise!
 

Hello fellas, I have a 2018 Camaro 1SS. I have this constant buzzing/static/high frequency noise coming from my rear side speaker, more on the passenger side. I cannot seem to find the cause or fix on this. I need help, it's driving me crazy. It's on all the time and when I accelerate at time it gets louder. Even turning off the sound system it's still there.

there is an x wife joke in there!!! lol!!!

I'm dating myself but I had an older high horsepower car and the radio would pick up the ignition system - sounded similar to what you are describing. How does the car run??? any slight mis-fires / misses??? I'd check the grounding paths of the coil packs. Easy place to start

Lol, I see the joke now. I need to check this more often, sorry for the late reply. My car has a stage 3 upgrade, cam, headers, heads, throttle body, tune, etc. No misfires or engine issues. The noise would go away once every 10 times which is weird, nothing in my routine drive changes. It's weird.
