Mine has done the same thing. I have not yet changed speakers as I do not have a warranty. I have also noticed that lithe radio/speaker will skip/ stop playing for a second at random. Then start playing again a second or so later. I have only had it for 5 days!Started the Jeep this morning. I saw a yellow speaker symbol with an exclamation mark in the bottom right corner of the EVIC with the message above.
The 5" radio (6 speaker system) worked fine but no driver dash speaker in any reception mode. So I disconnected the neg battery cable and checked the speaker and the wire to the radio. All was fine. Head scratching ensues.
I then swapped the good passenger dash speaker to the bad driver position. Then I reconnected the battery and it worked. Basically proving the head unit and wire is good. So I suspect a bad driver speaker.
Until I tried the bad speaker in the good passenger corner, and now it too worked! Wha?
With speakers back in their original corners, I cycled the ignition, no message, all works fine.
Conclusion: unknown cause of message. Could have saved some work with starting at disconnecting the battery and clearing the system first. Then dug into the components second.
