Hi everybody, As im new to this site I hope im not asking a daft question. I have an Audi S3 8L and want to fit a new stereo. The one i have just taken out is a Kenwood I need to know what all the plugs are, I have yellow red blue and green plugs with a normal iso adapter any help would be great.

Thanks Chris.
 
The yellow/green/blue is
yellow - for the pre-outs (to feed the rear amp & sub in non-Bose, for Bose it feeds the Bose amp which feeds all speakers & sub)
green - DIS (no aftermarket HU works with the DIS)
blue - CD changer (no aftermarket HU works with the Audi changer).
The black ISO is just standard power (althought the perm live & ignition on are reversed)
If you have non Bose you will also have a brown ISO speaker plug which is only wired for front speakers.
You'll also need a powered antenna adapter to getthe radio working:
