New HU in my S3, CT51-AU01 issues?
Hello, well I have finally bought another S3 (my 3rd now)!
I am in the process of fitting my Alpine HU in it and have bought the CT51-AU01 to wire it in as the S3 is full Bose. Firstly is this the best thing to do or would it be better if I bypassed the Bose and used the HU to power the speakers?
Second there is a blue wire on the adapter that seems to go no where, a black wire I am guessing that has to be earthed and also there are are 2 wires in the red block from the car not being picked up by by the CT51-AU01 ?
Lastly, there is a male and female ISO and as far as I can tell i only need the male to go into the HU, what is the female for? ANYONE? I have searched the internet with no joy.....
