Again an issue with the estate variant i think. I'm trying to replace my front speakers with some new components. The wiring diagram in the Haynes manual for the 6N2 however shows different coloured wires from those I have in the car. Mine are red/yellow and brown/yellow. Anyone know which is the positive and which is the negative?

Also any tips on places to fit aftermarket tweeters? (the originals form part of the mirror cover assembly and can't be removed themselves)

Red/Yellow is the Pos & Brown/Yellow Neg
