    Hi

    I have an E46 M3 and recently replaced the Business CD player with a Professional CD player.

    Baris upgraded the amp to the Carphonics Stage 2 amp inside.

    I've replaced the speakers with Bavsound's Stage One Package. And under the rear shelf, I've replaced the HK subs with the Kenwood powered replacements.

    At zero volume, I get a permanent, faint buzzing sound. Baris has tested the HU and says it's not related to it. Would be great to hear if anyone has had the same problem, and managed to solve it?

    Many thanks

    Typically buzzing is an earthing problem ...have a read up about ground loop isolators and see if the Kenwood amp needs one
