Can I delete the ANC?

[Rapchizzle]

Hello! I got a 2020 Ram Big Horn Quad Cab with 5.7 Hemi a couple days ago and am just learning about the ANC. I do not like how it affects the sound when listening to music and want to disable it. I have tried searching but have been unsuccessful.

Is there a way to disconnect the ANC or delete the system altogether? I don’t mind engine noise if it means no annoying distortion to my music.

Yes. There are a couple options, depending on which audio system you have.
Cheapest way is to disconnect two pins which are the cabin feedback microphones.

I have the non-amplified system, and settled on a Datalink Maestro ACC-ANC-CH3 bypass cable that I got from Crutchfield. After installing it, I notice there is no longer anything connected to the module under the driver seat, and there is a good chance that space may be taken over by amateur radio. A job for another day, as they say.

The amplified (HK?) system may take a different cable, I'm not sure. HTH.

I have the unamplified basic audio system with 8.4 inch screen.

Are there any diagrams or instructions for finding those two wires?

Check out this thread, also you could put in some more details about your Ram in your signature this would allow forum members to better answer questions you may have about your truck. Information to include such as the trim level, engine type, option packages and modifications that have done.

Here is a write up I did for another forum. I have a 19 Bighorn Base 6 speaker audio. ANC was causing all kinds of issues. I like to hear my exhaust rumble and HEMI rev, ANC is not something I’m attached to. I will be redoing the audio (hence not wasting money on factory upgrades) and adding...

If you have the 9-speaker mid tier system, it's unpin these 4 wires (one for each ANC mic) under the drivers seat. I upgraded the 6x9's in the door and the truck was undriveable due to thunderous speaker feedback. There are cleaner bypass cables you can use instead though, as mentioned.

In my 2018 Trackhawk which most likely has the same ANC set up, you could disable it by unplugging one of the 4 mics in the headliner. PAC Audio also makes a plug and play bypass harness, if I'm not mistaken.

I had the 4 wires unpinned for a while which worked but eventually got the bypass harness.

For the base 8.4 without the amp I used this:

This has been super helpful. I have ordered the bypass harness and some Kicker 6x9s for all 4 doors from Crutchfield. Thank you!

There are also harnesses you can get for about $20-$30 that don't require the pins to be popped out of the harness if you're hesitant to do that. PAC makes one and there are some other vendors that made similar ones. Just google "ANC bypass" for your model year.

their is a option to disable it using alfaobd. I am not sure if it actually works or not, but I was getting a error message pop on my 20 big horn for the frame mounted anc and I was able to turn off the module.(no more error). I've played with the option but never noticed much difference. Keep in mind my truck has loud howling 35's and no muffler so their is nothing quiet about my truck. so your results might vary. I left it on and upgraded the front door speakers and dash speakers with a set of 4ohm kickers and it woke the sound up drastically in clarity and general loudness.

Maybe this?

Granted, I had the HK system in my 2020 Laramie and now in 2024 Limited, but when I disabled the ANC in the 2020 Laramie, road noise was not the issue; exhaust burping was. It would trigger mainly when going up hills. It was quite annoying. I was able to get rid of the road noise with treatment (not just dampening but absorption material as well).
