I've recently got a replacement (Android style) head unit which replaces my concert II. The car is an A4 avant style with rear amplified speakers (front driven directly from HU).
Having connected it up and got it all working ok, my rear speaker volume is very low (but the sound is clear). I've done some digging around and suggestions appear to range from
1) making sure the rear amp is getting switched power
2) directly wiring speakers to HU
3) ditching the rear amp for something better
4) HiLo converters.
I am a relative newbie to all this and would like to get this up and running better without the $$ of new amps for now.
I have looked on my HU and there is a "AMP CON" wire out. But I am not sure where this would connect up to the old harness. My old concert II diagram was like this one and so I have the "speaker side" connector which matches up to this one:
Where should the AMP CON connect to.
Also does anyone have a list of what these abbreviations stand for (I get most of them but AU PL? CDC? etc)
Thanks
