    Hi Guys,

    Well apparently a big thing that should be done in any car with an audio setup is to upgrade the BIG 3...

    These are:

    Battery +ve - Alaternator
    Battery -ve to the body of the car
    -ve from the engine to the body

    I think that is them anyway... how easy would this be to do on the S4/A4?
