    Im pretty aware this has been asked loads of times, so im going to lay it down as iv understood it.

    Iv been told by a local audio shop that i will need at least 2 different harness to make the steering wheel work with the radio and then the rear speakers and sub with radio.


    Iv read a few pages and how i see it is...

    Obv need to run a power cable through car.
    I need to ground the system.
    I need a remote (i will have to check radio schematic)

    Next would be the the new sub itself, I have no RCA on the back of concert II so i would have to tap into the wires connecting to the standard sub?
    As for amp id need to find a way to also connect it to the rear speakers, aswell as the sub?

    I really dont want to have to take this to autosounds as theve quoted me around 450-800 depending which option i go for.
    (this is without me buying the sub/amp and wiring)

    someone point me in the right direction and id really appreciate it.
    Chris.


    EDIT, i have a 56 audi a4 b7 with concert II + built in sub.

    You just need to run power, then you can pick up the rear pre-out feeds and remote from the stock amp loom. Just cut the end off an RCA cable and solder/crimp small blades to the left/right and common screen. These can then be inserted into the blue plug in the corresponding slots along with the remote to feed the new 4 channel amp. You then have 2 channels for the rears which need to feed back into the blue plug to pick up the rear speakers, and 2 channels bridged for the sub all running off the rear pre-outs.
