2002 audi a3 replacing full bose system with 7" monitor & new speakers

    I have A3 1.9TDI 130 sports 5 door 2002 which currently has sympathy II headunit and bose subwoofer and speakers.

    I am going to be replacing the headunit with a 7" monitor / bluetooth / video - which also has RCA cables for the front, rear and for the sub which will all go into my 6 channel amplifier.

    The speakers are being replaced with new edges 5.25" front and 6.5" rear door - these speakers are 70/80watt RMS which match my amplifier.

    I also have 12" 1100watt subwoofer which I am planing on making a fiberglass enclosure in the boot for.

    So the plan is to have the amp in the boot (Can't think anywhere else it would fit) So I will need to run 5 RCA cables from the headunit to the boot.

    What is the best way of doing this?
    Does anyone have a map of all the audio wires?

    I also can not find an adaptor for the headunit? new facia and a cage.

    So the current plan is (I work in an engineering company) to produce a 2mm thick stainless steel facia that will have brackets to secure the headunit and then have X4 security bolts Countersunk into the facia to bolt to the old cage

    I am also sttuggling to get my door panels off to get to my speakers, am unable to find any of the screws? seems different to all the other guides i can find.

    You don't need a map of the audio wires as you won't be using any of them.
    Removing the door cards is pretty easy. First lower the windows, then remove the 2 visible screws at the top on either end of the door card, remove the single screw inside the grab handle, push down the plastic cuff inside the grab handle and remove the 2 screws behind it. Pull the whole door card straight up and out, but not too far as you need to unhinge the door release cable and unplug the wiring looms.

    All the cables run under the side trim, there is plenty of space.
