I'm having a high pitch whine coming especially from the passenger side. The pitch gets louder with rpm changes. It's constantly there, as soon as the car is on, whether the car is idling, accelerating or decelerating. This whine comes from the speakers, because when I disconnected the oem bose amplifier, the noise was gone. I believe this is known as the "alternator whine" so I changed a new alternator told by the dealer, and changed to another oem bose amplifier, but the "whine" still remains. The high pitch noise is very annoying and causes migraines.
