2019-up Dodge Ram 4-Channel Signal Harness with ANC

I have been selling and installing audio equipment for over 15 years and one of my rules for installing is to do as much of the prep outside of the vehicle. The less time in the vehicle, the less of a risk you have of damaging something and it generally makes it faster since working at a bench is better than an awkward position in the vehicle. This is one of the main reasons we like our T-harnesses for our Dodge Ram customers.

This harness fits 2019-up 5th Gen Rams, 1500, 2500 or 3500 with Active Noise Cancellation (ANC), BUT NOT Alpine or Harman Kardon. On 5th Gen Rams, this harness will only work if you have 6 microphones in the headliner, and not just 2 above the front seats. You do not have ANC if you only have the 2 microphones.

It is a plug-n-play harness that plugs in at the ANC module under the Driver seat on the 1500 and under the driver side dash if you have a 2500-3500, and has your 4-channels of speaker wire installed already. Other than installation simplicity, it also keeps you from cutting up the wiring in your brand new truck.

The 5th Gen Ram has some new twists. Ram couldn’t leave it alone, but this is actually for the better. On the 13-19 Rams, load resistors were the complication. But not this time. now it is ANC, or Active Noise Cancellation. What this system does is the audio signal from the radio goes to the module below the seat. Then 3 microphones in the truck pic up road noise in the cabin and feed it back through to the speakers to null out what noise it sees. The complication with is that when you add in new audio equipment, it “sees” more “noise” and tries to cancel it. The short answer is that if you want to upgrade anything, amps and subs, you will need to get around this system to get the results that you expect.

Now, the cool part about this system is that power, ground and all your speaker wires are under the driver seat and also bypasses all of your ANC microphones. Meaning you can do all your amp wiring without having to pull the radio out of the dash. The module is under the driver seat and has two plugs, so this is a super easy installation.

This harness comes complete with 17′ of speaker wire installed, so it is ready to go to your interface or DSP of choice, with no need of load resistors. This harness is tied into all the speaker wires and power and ground on the harness. So all you have to do is get under the driver seat, unplug their harnesses, plug in our harness, and run your RCAs and remote to your amp. Nice and easy.

This does not have wiring to go back to the speakers from your amp, so you will have to run new wiring there somehow. We do make a harness that has the wiring on it already which will make things much easier.

We also have a version of this harness to do a 4-channel or 5-channel amplifier, or a signal processor, or whatever it is that you are wanting to do. If you have any special requests or variation of this harness you need, feel free to ask and we will get it made up for you.

This will not work if you have the Alpine or Harmon Kardon Systems. If you do, there is a better solution. AP4-CH41
