Hello. I have S3 8l with BOSE. The car came with RNS-D, but i sold itnand bought pioneer double din HU. I bought PC9-410 and 2 GLI's The problem is that there is a lot of whine coming from the speakers. It starts when i turn the key in accessory position and when i start the engine it gets even worse. The whine is increasing with RPM increasing. Any solutions?
