To disable the noise cancellation, the cabin microphones must be disconnected:
See the picture in post#11 to identify the X3 connector. Pull the pins out (or cut the wires) that go to Pin#4 (Light Green with Brown stripe) and pin#5 (Light Blue with Yellow stripe).
The pin numbers of X3 are shown in the 18th picture in post#1.

Here are the pics of my install with close up of the speaker wire you tap into and my ground and power. From the +yellow and -yellow and black speaker wire I used a LC2i. So the +yellow and -black and yellow wires go into the LC2i speaker wire positive and negative locations. I powered the LC2i straight to my battery just like My amp and the LC2i ground went into the same ground as amp. The LC2i remote wire "OUT" went into my amp remote wire in, to turn my amp on. The LC2i WILL NOT TURN ON until music is coming out of the speaker wires. It senses a current from the speaker wire and that what turns the LC2i on. The LC2i will not turn on with just with power and ground hooked up. (I thought mine was a dud because I hooked up the power and ground but NOTHING happened. Not until I put the speaker wire from the +yellow and the -yellow and black, did the LC2i turn on.) you then put the RCA sub out from the LC2i to your amp. When the LC2i senses music it will then turn on then turn on your amp. Remember remote wire out from LC2i to remote wire in to your amp or your amp will not turn on. I used the LC2i cause it sounded better than the $20 ones and it's adjustable and will turn your amp on. Here are some pics




Ground goes here for amp and LC2i
Power here
This is from X1 connector and the 2 yellows you use are here

The 2 yellows you tap into for your speaker wires

Power
The LC2i

how do I know where to put the rc cables? Do u just took the yellow and yellow black out and put them in your lc2i? what would happen if you spice them two wires left them connected to both? So it would still be connected to the factory amp and the LC2i

Thanks for the write-up! For those of you looking for a 12v remote source (my converter's auto-on has never worked right) fuse #37 is what you want to tap. It turns off when you open the door after turning the car off.

This is an awesome write up with great replies too! So good I thought I had it in the bag! Can anyone tell me why my wiring colors are different than the other posts? Trying to find the ANC mic wires and the front right door woofer.
'16 Z06 2LZ

Any help appreciated, thanks!!


Never mind that post, I figured it out.

But...does anyone have a easy way to run the bass **** from the amp to the front of the car?

Thanks!
