Hi, I've done a quick search but couldn't find anything - I've just bought an 8L S3 and am trying to remove the rubbish head unit that was there and put back in a Concert II CD player... I've got the old HU out and have power to the head unit but no sound. I've got BOSE installed and there's a random box of gubbins in there (see below) which has a speaker connectors coming out of it and a blue / white striped wire.
I guess this is the remote on which needs 12v to tell the amp to switch on. Where are people taking this from - I'd have normally used those switched live red / yellow wires but there aren't any, so was kinda expecting somewhere I could use in the OEM connectors.
Also, there's a random (which I guess is an earthing wire) that can be seen below - any ideas where this should go?
