Hi Jeep community I have a 2018 grand cherokee overland with active noise cancellation and I was wondering how it works because I've heard that it's only on when eco mode is turned on or dose it come on as soon as you start the car and my other question is if I wanna do some audio system upgrades to the Jeep will it affect the system in any way because I don't wanna mess with it if it will cause the system to no longer work would love to here your guys opinion on this thanks
