    Hiya mate, if your getting a whining noise, youve got a bad earth connection, try bolted the earth wire to the body of the car, should help

    I get the same. Where do you run the bolting wire from and to? I presume you bolt it from the headunit. I was thinking of 2 crocodile clips on wire would be best

    Just going on previous experience, the head unit should be a direct feed from the battery due to power consumption dont forget the in-line fuse, i.e. if not you can see the light dimming on the head unit when you use the electrics from the car. This way you will get an independent feed hence iliminate any whining, same principal when fitting amps you have to have a strong ground and a decent live i.e. use proper gauge cable/wire.

    To be safe Id ring a local ice specialist for recommendayion - anyway hope ive been helpful

    I had the same issue with my HU and an Autoleads lead. In the end I decided to install a new amp and power the rear speakers and sub from it, leaving the HU to only power the fronts, this seems to work fine.
    I also took a switched live from the fusebox, the S-CONT fuse, so that the HU switches off when the key is removed.
    All this was recommended by AndyMac, very helpful fella.

    Is it not cause you have the two of the wires running side by side? Run one down one side and the other down the passenger side. From experience done this and everything was sorted.

    Is it a Bose system or non-Bose?
    Is the whining coming from all speakers?
    All these interference issues are largely due to the shambolic mickey mouse Audi wiring feeding the low level pre-outs to either the 4ch Bose amp or the 2channel non Bose amp. The plug at the HU end is completely un-shielded so any electrical noise from the engine/alternator will be picked up and then amplified by the Audi amp in the boot.
    If you have the Bose system it will effect all speakers, non Bose just the rears.
    Easiest thing to try first is to connect a fairly chunky earth cable (12 or 8 gauge) directly to the chassis of the new HU, then with the glovebox removed try grounding this lead on different parts of the car chassis with the HU on and the engine running. Hopefully you will find a location that cures the problem. Also burn a CD with silence on it so you can play that at the same time with the volume jacked up so you can hear what effect its having.

    i got the same thing happen to mine when i added a sub. does the whine co-inside with the revs?
    if so i solved mine by using a ground loop isolator. they stop ground loops which is whats happening. because if i remember its because of multiple grounds on the system. it plugs into your amp RCA, and into the feed from your HU. about 10-15 quid i think they are.

    Are you running an AMP in the car ?

    If the power lead to the amp isn't well enough insulated it will transmit the running niose of the car, very wierd.

    could also be bad earth as boyo above has mentioned.
