JVC HU Install and wiring help needed!
Folks - need a bit of help -
Have bought a JVC Head Unit to wire into my Audi A3 2005 (iso, single din, audi concert ii).
I am getting power and sound from the front speakers, but not the back. The radio reception is non-existent at the minute.
So I purchased a PC9-404 to connect to the rear speakers, but there's an extra blue lead that doesn't connect anywhere.
I also purchased an amplified antenna adaptor - again, there's a blue lead that i don't know where to place.
If anyone can make sense of the picture i have attached and where I'm going wrong then it'd be much appreciated!
