Hello Fellow TLX enthusiast!
This is my first post on this forum. Let’s try it out!
I started the prep work today on my fiberglass trunk side mount 1000W sub project. I couldn’t find any good videos or articles on disconnecting the ANC/Active Sound Control Unit and thought this might be useful to some.
I have the 21’ TLX Type S 17 speaker system but can only assume this is the standard location for the 21’ TLX.
The module is located directly behind the push-button start but is accessed through the driver foot well area. You will have to remove the following trim pieces in order:
  1. Driver’s Center Trim (The one with the push-to-start button)

  2. Pull the Driver’s side weather stripping back

  3. Driver’s Dashboard side lid

  4. Remove the Phillips screw on the side of the lower cover

  5. Diver’s Dashboard lower cover

You should now have access to the Module. The 20-pin connector is plugged into the top of it and has a push tap on the front center of the connector. I just unplugged it and push it off to the side.

I found it easiest to pull the panels straight out towards me instead of jerking or prying the tabs out. I was able to not break or bend any of the tabs. Just take your time and you should be good.

I found disconnecting the ANC had no effect on the sound system. After researching and finding out how it accumulates the noise canceling algorithm thru dynamic sensors located throughout the body of the car I can understand why it has no effect.

I found the exact opposite.

You can research it all you want but disconnecting the ANC has solved the random sub feedback issues in my last three aftermarket sub projects, including this one.

Well some guys are having warranty issues with their FAKRA connectors and experiencing infotainment problem's, while some are not . Every car is different.

And this thread was created for guy's that are experiencing issues post sub install and would like to try disconnecting the ANC.

This worked perfectly for me. I recently added a kicker L7 15’ with a 3k taramp to the stock radio and every time I cold started the car and accelerated/ brake the bass would hit hard as if music was playing. Once I disconnected the anc module, not only did that stop happening but the music and car got louder and crisper.
