Wires getting pinched in door? How do you have the wires ran? Power ground on one side, signal wires on the other?

Everything ran separately nothing goes through doors I've heard it could be the active noise cancelling anc just trying to figure this out so I can enjoy the extra bass . Every thing wire to center console to the lc2i

You need to unplug the factory subwoofer from under the cup holder, because of Active Noise Cancellation (which uses the subwoofer)

I had the same issue, and this solved it.

I tapped into the subwoofer lines under the cup holder and then found the remote wire by the trunk release handle on driver side.

It's the noise cancellation system. It's activated when the doors are closed. Took me months to figure out. There are 2 round vent looking pieces slightly larger than a quarter on the drivers side. The noise cancellation one is the back one I believe. Open drivers door and remove the rubber around the door frame so you can slide your hand between the roof and the headliner.there should be some wire under some foam block. It is kinda hard to pull loose. There will be a green plug on the wire. Unplug the green plug and it should fix the problem. Do not try to pop the covers off from underneath. I did and one broke. Lesson learned. Hope this fixes your issue.

We ran into issues running accessories out of the ciggy lighters. We didn’t check to see if the opening the doors would kill the feedback. It was odd because on some trips, same accessories, all worked fine, other trips, we got feedback like that. See if you can find an adapter for USB that has a filter in it.
