Hi all,

I hope someone can help.

I have a 2007 A3 with the Audi Symphony system.

I am in the process of fitting an aftermarket Pioneer double din stereo. i've completed what i think is correct so far,

wired the handbrake switch correctly (so i cant watch DVDs whilst moving) - works fine)
taken an ignition power feed - works. all appears to be working, stereo remember radio stations etc.

The only issue i have is the rear speakers are not working

Would i be correct in thinking the rear are amplified? if that is the case then they should be receiving power i guess.

Have i got the wrong harness? maybe i should bypass the amp for the rear speakers. any ideas where it is?

i appreciate any help guys.

cheers
