Audi Concert Bose speaker system with new headunit issue!

[Exemplaar]

Hi everyone,

new to the forum.

Had my 8p nearly a year and finally got a new head-unit so I can play music off my phone. Did some research on here etc and bought additional harness for the the whole system to work and I know people have had issues with headunit not turning on at all and only the front speakers working...managed to get round the headunit power issue but can't get my head round why the rear amp and speakers still won't work as everything seems in order on the harnes...

HELP!?

Sure they are not working at all? the rear sub and speakers seem to be fainter with aftermarket HU's. I compensated using the front/rear fader, so try that before you rip all your cabling out again.
Also ask the same question on the ICE forum, lots of Geeks on there.

it also works for non bose, i'm trying it first with a high/low convertor before i buy this though.
