- 2019 Challenger Widebody Scat Pack
I took delivery of my 2019 WBSP this past weekend and on the drive home from the dealership I encountered an issue with the Harmon Kardon sound system.
When the car goes over bumps in the road, the front driver’s side door and left dash speaker intermittently cut out (no sound) and then come back within a few seconds.
As I had a fairly long drive home from the dealership I was able to narrow down which speakers were intermittently cutting out by adjusting the fade control to the four different quadrants of the car.
When the fade control was set to the front drivers side there was no sound coming from any of the speakers when the intermittent cutout takes place.
My hypothesis and hope is that there is a loose connection at the amplifier as more than one speaker is experiencing the same issue so it is unlikely a loose connection/short at a single speaker. However if the two (or more) speakers share any common wiring there could be a short or pinched wire in the harness.
Under normal circumstances, I would have turned around and just brought the car back to the dealership, however the car showed up two weeks early and my wife was literally on her way out the door to go see her sister in Milwaukee for the weekend when we got the call that our car was at the dealership and ready to be picked up. My wife agreed to delay her departure so we could go pick the car up with the understanding that she had to leave for her sister’s right when we got home.
Before I make a service appointment and take the car back to the dealership, I would like to know where the amplifier is mounted and how to gain access to it.
If it is something as simple as a loose connector I would prefer to try to rule that out on my own.
From the diagram on Harmon kardon’s website, it looks like the amp is in the front of the vehicle, possibly under the dash?
Any help is appreciated!
Thanks,
Eric.
