static

I have a 1999 mustang gt with the 35th anniversary package and Mach 460 sound system. Recently I hear a static like noise coming from inside my dash. I only hear it under acceleration at 1700-1900 rpm. When I bought the car the stock radio didn't work. The radio unit turned on like normal but no...

recently now that its been colder in the morning wheni go to start my car i have a high pitched static sound coming from my speakers. even if i turn the radio completely down the static is still there. i've also noticed that as i rev the car up the sound becomes more prominant.
