    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?
