About the iDatalink bCH3

Stop noise-cancelling feedback

Your vehicle's active noise cancellation system (ANC) plays havoc with an aftermarket system's output — with bass tones building up and then disappearing, over and over again. Whether you knew about this issue before you got your amp or sub, or found out the hard way, you need to disable the ANC in your vehicle in order to get good sound. iDatalink's bCH3 ANC bypass harness plugs into the factory wiring as a jumper that bypasses the noise cancellation module, allowing your new system to play the way it should.

  • ANC bypass harness
  • for select 2017-up Chrysler Pacifica without a factory amplifier
    • ANC module located to the right of glove box, above passenger kick panel

Customer Q&A

3 questions already asked

After installing an amp and replacing the factory speakers (because the factory speakers are terrible) in my 2020 Ram Lonestar. I have this droning noise now, does this product REALLY bypass that droning noise? Or does it just makes it quieter?

Yes sir it actually bypasses the droning, I added a sub and the drone coming through it was horrible. This made it go completely away and I don't notice any difference when using my speakers to talk on the phone. Not to mention it takes longer to move your driver side seat forward than it does to install this. Hope this helps
[ RICARDO  Sep 04, 2020 ]  Staff
Assuming you have the base six speaker audio system this harness bypasses the ANC (active noise cancellation system). as you have added an amp and upgraded the speakers this has drastically improved the sound level inside your vehicle therefore I'm inclined to believe that bypassing the ANC module will rectify the droning due to the ANC module attempting to cancel out high noise levels now present in your cab from upgrades.

Do I connect this adaptor to the amp under the seat in my 2019 Ram big horn?

Under the drivers seat is the active noise control module it's not an amp. Yes this plugs in there. It is very easy to connect and disconnect. It helps with audio sound. It's still not perfect. From my half vast research there is another module for the ANS under the hood somewhere that I haven't figured out where it is and wether or not it can be disconnected. Sure would have been nice if Ram would have put an on off switch on the ANS.

Unhook the wires than Connect them together with the link if you need speaker hook up for an amplifier Those are speaker wires
[ CHARLES  Aug 11, 2020 ]  Staff
It does not go to the amp You disconnect the wire harness's from the amp and that adapter connects the wires together It is designed to bypass the amp or active noise control This does not cancel out the ANC all the way You still have to disconnect the mics in the headrest
[ Michael  Aug 11, 2020 ]  Staff
Yes is real easy
[ ALFONSO  Aug 11, 2020 ]  Staff
No. The ANC gets unplugged and the two harnesses that you unplug get connected. You can remove the ANC module entirely if you choose.

Does this product work for a 2020 Ram 1500 Laramie Edition?

This works for base 6 speaker stereo If you have Harman Kardan or Alpine it may not work.
[ SCOTT  Apr 01, 2020 ]  Staff
If it has the base 6 speaker system, then yes.
