Only one day with the fix ...
The sound levels and freq response seemed to have a mind of its own after I fitted an Audiosources AS-8603
http://www.audiosources.net/prod_view.aspx?TypeId=50004&Id=167&FId=t3:50004:3
and later also an Erisin headunit es-7683a
http://www.erisin.com/erisin-es7683...mcd-dvrin-dtvin-iphone45-audi-a3-s3_p519.html
Both these units were plug and play for the 4 channel Bose system (Couple of tricks to fit correctly)
BUT the sound was never quite right...
After searching on here and other forums I found links to the term AudioPilot?
It would seem with the Audi Concert 11 etc you can adjust various settings to do with frequency response and ambient sound levels. You can't set these when the headunit is replaced as only the Audi unit can talk to the Bose amp . (vcds doesn't recognise modules)
Further research suggested unplugging the microphone in the overhead console where the cabin lights are.
You just pull off the rearward grey cover and there is a rectangular block (microphone) there. The plug just pulls out from the main assembly. Some people had success, others not so.
On my drive to work today... the sound level was constant... the frequency response was back to normal..yayy..low freq boomp from the sub again
Now I will probably have an Audiosources headunit to sell as I wont need 2 off. Initially I blamed the unit .
