Audio output signal bad 2018 RZX2

[azbjamin]

Hi all,
The output for my tower speakers stopped working. Does anyone know if there is a way to repair this or does it require the entire touchscreen head unit to be replaced? Given the price point I may look into a stand alone head unit. Has anyone done this before?

2018 RZX2 as stated in his profile next to the post, under his username as well as its the tiles of his thread.

The media unit on a 2018 would be the Murphy ICE black box.

The output for my tower speakers stopped working

Was this determined by putting a volt meter on the tower zone outputs at the ICE box and there is no voltage at any volume level when compared to the voltage of the other three zones? Did you swap a cabin zone RCAs with the tower zone RCA at the box as a test?

Or,

Have the tower speakers just stopped working and the assumption is, its the ICE box
