Equinox/Terrain ANC

Hi all,This is my first post here.I build amplifier bypass and sub integration harnesses for 2010-2017's and most people who do audio upgrades in these disconnect the microphones from either the headliner or ANC module.Some just pull the #7 fuse at the interior fuse panel and that produces mixed results. Recently a female customer asked me if I could make it possible to bypass the stock amplifier and yet maintain all ANC functions.Looking at the wiring diagrams of the ANC module it seems that there are 5 pins at the stock amplifier speaker output connector that are connected to the ANC system.One is an amplifier sense signal and the other 4 seem to be the outputs to the stock sub and front doors.Now I have all the OEM plugs and pins to make a harness that could send all 5 of those ANC wires back into the stock amplifier while still providing the speaker output wires for all the doors to go into the aftermarket amplifier.So does this sound like it could work?I don't want to build this lady a harness that doesn't do what is promised.Thanks for any input on this!Rumors of Bob but never Bob......So what is it you tell people you do these days Bob?

I find the answer to this by studying a proper wiring diagram.It can't be done like I thought.But it could be possible a different way by sending the wires back into the stock amp and then using another speaker out plug sending those wires to the speakers .Basically using the stock amplifier for ANC only.Rumors of Bob but never Bob......So what is it you tell people you do these days Bob?
