    Chorus to Concert upgrade

    Hi All

    I brought my 1st A3 a month ago 2009 1.9 TDIe. I have decided to upgrade the HU as the Chorus with front speakers wasnt doing it for me.

    I have managed to source a Concert II HU, subwoofer and rear speakers, really cheap, but have no idea how all this will fit together.

    Has anyone else carried out this upgrade/mod that can offer advice on wiring looms, wiring diagrams and how it all goes together

    Thanks in advance
