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.

Q
I have a 2019 ram 2500 big horn with the base six speaker system. The volume does not get louder after 22 and seems to go in and out. Will this rectify my problem? Also, where would this need to be plugged in if I don't have an amp?

While I did not have an issue with the volume topping out at 22, I did have the issue with the volume going in and out. Purchase and installing this item addressed the issue. Note that it is located under the steering column to the left-hand side, not under the driver seat as others have mentioned.

Couple questions to answer this. 1. What engine? 2. Do you see the ANC unit under the drivers seat? If you do, then getting this harness will eliminate that box. Volume issues are 2 fold. 1. ANC and 2. Issues with USB over music. You'll find that listing to your truck, with NO usb devices or phones plugged in will be louder then if they were plugged in. Try listening to music from your phone.. First through USB... Then try Bluetooth (remove all cables) make sure your volume to your phone is at its max! You will notice Bluetooth is louder, and more clear when not using a USB cable. Removing ANC will help this a little bit. Next step, go to fader options.. And move the fader to the front 2-3 clicks. You'll also notice it gets louder and bass hits better! Factory deck can't push all the speakers as well as they should. So, I move the fader towards the front to allow the amp to power those better. Again, you'll notice it goes louder.
In the end, all we have are work-arounds for better sound... Sadly no fix, other then adding amps.
Again, I did my tricks with the radios settings.. And removed my ANC.. Added a mono block... purchased the subwoofer from Mopar direct for the HK radio system... I added this factory sub, with a kicker amp to fill the bottom end that's missing. Doing this saved me space, and gave me a full balanced sound. If you need more info, let me know.

There is also a update from dealership for the anc.
[ VINCENT Dec 29, 2020 ]

Yes it will my speakers would cut out and come back on. This eliminates the noise control that cuts speakers off when loud.
[ VINCENT Dec 29, 2020 ]

this replaces the box under the drivers seat. This may help you with your fading in and out.

Q
is there a wiring diagram for the iDatalink bCH3? like to tap into the wires here so i don't mess up my factory wiring. Adding a powered sub and need to tap into speaker wires.

As mentioned... not only does this harness have the proper aftermarket color scheme for the wires, but they are in proper place. Tap off the front! White and gray wires! You don't want to tap off the rear. Many reasons.
[ DAVE Dec 29, 2020 ]
A
Yes it does have a list of which color wires go to which speaker. Also has the pin diagram.

Q
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?
[ Brian Sep 01, 2020 ]

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 ]

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.

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.

[ CHARLES Aug 11, 2020 ]
A
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 ]
A
Yes is real easy
[ ALFONSO Aug 11, 2020 ]
A
No. The ANC gets unplugged and the two harnesses that you unplug get connected. You can remove the ANC module entirely if you choose.
