    ok i have a 110 se tdi 1996

    rear speakers dont work

    looks like wires are missing in block behind headunit

    the brown connector block only has 4 wires coming from it

    is there another block for the rear speaker on these with an aftermarket head unit

    from the factory the rear speakers are powered by an amp.As you have an aftermarket headunit,you need an adapter to connect the wires for the amp to your headunit.I changed the rear speakers and ran new wiring on mine.

    The wires on the small yellow block are for the amp and rear speakers. one of the White wires, a yellow wire and purple i think iirc. One white one is a 12v remote for the amp. BUT, these wires are very thin and someone said they are earthed (all something to do with audi's amp)

    I ran some wire from HU to the rear nearside boot liner. In there is the terminal block for the amp. Red/Green & Blue/Green is right and left POSITIVE respectively. Brown/black & Brown/Red are negative.

    This is plug inside the trim area:
