Hi guys, im sure its been covered many times but i cannot find the info i need to solve my problem.
I have a 2004 a3 with the concert headunit. I am trying to fit mty alpine unit in using the autoleades PC9 - 404 lead.
I can get the radio to work and the unit to work on the front speakers but cannot get any sound from the rears..
I am aware that the rears and the sub run off of an amplifier which is supplied via the 3rd plug on the lead, however all the leads i have seen are missing 2 wires from the centre part of the 3rd plug.. does anyone know what these wires are and how to get it working?
Any help gretly appreciated.
Thanks
