I have a 2015 Jeep Grand Cherokee SRT, and I’m bit of a music buff. One of the first things I dispensed with was the factory Harman Kardon speakers. I replaced the sub with a JL stealth box. Now I have a pretty big problem with the factory stereo and its the automatic noise cancellation.
When the transmission is in normal D mode and or eco mode is on, it uses the factory stereo to cancel out the drone of the engine. Unfortunately, the noise cancellation is calibrated for the weaksauce factory sub. Now it sounds like one of those bass CDs from the ’90s as I hold speed or decelerate. I’ve asked the dealer how to get rid of this thing, to which they said “you can’t.”
