High Pitch Noise!!!

[mharders]

I just had this happen to me last week, just started out of nowhere. I have Bose with a aftermarket HU. I just pulled the deck And made sure everything was securely connected and when I hooked it back up it was gone. So my best guess, like posted above is a loose connection (ground)

I pulled the HU out and checked for a loose wire/ground and nothing. Still the same noise. Im thinking it might be a bad channel in the amp!

it sounds like a bad ground honestly id try cutting your existing ground and grounding it elsewhere

I have the exact same thing going on........it seems to get louder relative to the acceleration..... it happens every third or 4th time I start the truck.....dod you have any luck figuring this out?

I had this problem about a month ago but I have aftermarket HU and all doors are aftermarket wired to an aftermarket amp. Solved my issue by getting some ground loop isolators and plugging them into my RCA's coming from the HU to the amp.
