A4 Stereo upgrade

[CliveH]

Hi All,

 

Just looking for some help really as I've got t a point in the installation and can't seem to move forward.

Equipment

1 x Pioneer SPH-DA230DAB + fitting cables including the steering wheel controller and Ariel conversion kit.

So far everything fits, but I can only get sound from the front speakers. I understand that the rear speakers are powered by a separate amp in the boot. Even though I have wired the remote switch (blue/white) cable from the head unit I still can't get the amp powered. (works fine with the OEM Concert stereo.

Can anyone either help or tell me the colour of the wire from PIN9 on the amp which I can locate in the quadlock of the cars wiring loom?

Thanks in advance.

Clive
