    You will have to run a switched live from the ACC in the fuse box to make it power up.

    The A4 B6 has a perm live, ground, K-line (blue/green), BOSE (brown) and possibly the DWA (brown)

    The switched live can be anything really, about the same as the brown wires would suffice. Yes you do not need the K-line (blue/green) or brown thin wires for the aftermarket system.

    ok thank you very much. i just read you can get a switch live feed from the cigarette light on center console or theres a red wire under the steering column have you heard of that

    cheers

    Cigarette lighter sockets are usually perm live in an Audi B6. I would go to the fuse box on the right of the car or the steering column. There are lots of perm lives around in your car so be careful you do pick a switched live.

    There are switched lives but these will turn off when you kill the engine, there is only one (as far as I could find) proper accessory feed that stays live until you pull the keys out and yes that is under the steering column
    Wiring in a proper accessory feed (ignition on) for aftermarket HU install
