ill just be sitting in my car or radio off and no noises and ill HEAR this very FAINT sound like weeeeeeeeeeeeeeeeeeeeeeeeeeeeee weeeeeeeeeeeeeeeeeeeeeeee almost like the supercharger sound but im not moving just car is on and when my foot goes near gas it makes liek a sound weeeeeeeeeee weeeeeeeeeeeeee

anyone have any idea

 

is that the voice in the back of your head getting excited?

but in all seriousness i think you could be picking up road noise out of the speakers... dont have to have the car on, nor be moving. do you have a cell phone in your pocket when it makes that noise... because i know some phone send noise through speakers.

 

maaybee its the radar?
