I've had the 392 for 1800 miles now. I installed an amp, capacitor, and sub woofer. Issue #1: active noise cancelling AND "fake engine noise". The car creates fake exhaust sounds which, even with the stereo off, is played through the speakers and especially the woofer. Several ways to fix this, some involve messing with the wiring harness. The easiest, and the way I chose, remove the 4 microphones overhead above front and rear seats. Remove them completely so they don't rattle.

Issue #2: sky one touch mutes bass output once open completely. You can bump the close button to get the output back but I'm looking for anyone that knows which wire from the one touch connects to the stereo so I can permanently disconnect it without impacting the function of the roof itself??

Wow! I hadn't realized the bass was muted when I open the SOT. Guess I never really noticed...

To be fair I don't have my 392 yet, but am I the only one who had no idea this thing wants to play fake engine/exhaust noise through the speakers? It really does that?
 
I’ve had mine for about 1,200 miles and there is definitely no engine noise coming from any speakers. Did you check to see if there is any grounding issues with the audio system you said you modified?
 
I have not detected any fake engine noise through speakers. If it did, I probably couldn't hear it over the exhaust. I have noticed the thing where audio gets louder the faster you drive and that is adjustable. Nice feature to make music louder to overpower wind noise.

One thing I'm not wild about is how it cuts a/c fan speed when you get a call. This "feature" is so the ac fan doesn't interfere with your call. It does this during voice recognition too, I think. I'd just as soon talk louder and keep the cold air coming.

I'll have to do some research (AKA get in the back while my daughter drives and see if I can hear engine noise out of the subwoofer). I also have not been able to detect the noise reduction system. I know some higher end Grand Cherokees have this, but I didn't think the Wrangler did.

Edit.....I just looked at my build sheet on crypto stickers and "Active Noise Control System" is listed!!

I'm actually shocked. What you might be hearing from the subwoofer is actually the system trying to cancel the exhaust noise. I can see where getting rid of the microphones would eliminate this.

Of course the subwoofer trying to eliminate the v8 exhaust note would be like trying to stop a tsunami with a garden hose or trying to stop a hurricane with a hand operated fan.

I have a “hiccup”. My radio display and system essentially restarts once in a trip. Does anyone else have this issue? It’s not life threatening so I figured I would just have it addressed at my first oils change,. I am just curious if it’s a common issue.

Agreed. A change was made and that's where the problem lies. The only exhaust note comes from the exhaust. Nothing fake about this Jeep.
 
That weird boom / drone sound comes on when the 4 cyl mode is activated. It “sounds” like it’s could be coming from speakers but it’s not. But what do I know… it’s my first Hemi lol

There is no fake engine noise. You have a grounding issue with the parts you replaced. Probably a shield not grounded correctly.
 
I have heard on a Facebook group the subwoofer changes tone with or without the hard top installed (or at least with the wiring harness hooked up). I would like to disable all that shit.

Simply put, that isn't correct. There is fake engine noise - it played through my woofers. A simple Google search would demonstrate this fact. Also, NOT the ground... It was literally the automatic noise cancelling + fake engine noise in this vehicle. Like I said, removing the 4 mics these functions both use fixed the problem in it's entirety.

There are dozens of articles and YouTube videos demonstrating how to bypass both of these functions.

Yes it really does that, and when a woofer is connected it's embarrassingly loud. It does it when the stereo is powered off, too, and there is no way to control the volume. While listening to the stereo the sound is still there but is lower in volume than the music.

Yes, I did. Double checked the entire installation. Removing the 4 mics used by the ANC & engine noise fixed the issue completely. If you aren't modifying your sound system you won't notice the added noise but once you do, it is impossible to not notice. Lol it was so loud through the woofer 🤣🤣. In retrospect I should have recorded it. Maybe I will reinstall the mics just to demonstrate that this vehicle, indeed, has synthetic engine noise 🤣🤣 didn't expect people to get so butthurt ... The dodge Challenger does the same thing. And Camaro and bmw, etc.

Me too. I am hoping to find someone familiar enough with the wiring of the one-touch top that they can tell me which wire to disconnect so the stereo stops getting signals about it's position. I can't find anything online about it yet.

I can’t find a single YouTube or article on this on google. Can you post the source? I actually listened for it on my commute this morning and heard nothing out of the speakers.

I think you hit the nail on the head with the engine noise, though I assumed the mics were picking up the sound and playing it back through the speakers and not trying to cancel it - based on how loud it was. There is a very noticable quieter difference now starting/driving it with mics disconnected. I certainly didn't notice anything prior to mods which is why it took a few days to troubleshoot it. It's an easy fix/bypass, but you have to sacrifice a little of the adrenaline from the beautiful roar of the hemi.

Someone recently told me his F-150 does it also!

Disconnect ANC/ASD mics:

Disable through wiring harness (not a wrangler specifically but similar audio issue with uconnect stereo)

The noise cancelling and engine noise use the same input (mics) to either suppress or amplify. I am going to reinstall the mics and record the sound (with and without the mics) and post them so people see what I'm talking about. This only becomes an "issue" when modifying the stereo speakers/woofer so I'm not surprised many are unaware - I was too.
 
@shany25m have you tried simply to cover the microphones, like tape them instead of physically disconnecting them just to see if that changes anything?
