Strange tone coming from speakers
Have a 18 Grand Cherokee Limited, Sterling Edition with the Uconnect 4C Nav 8.4 " display, 9 speakers, Sub-woofer and 506 watt amp. Turned the radio on today and a continuous tone could be heard from all the speakers, as far as I could tell. Turned the system on and off several times and restarted the vehicle, but the tone was still there. Several hours later I went back out to the car at the direction of the dealership to see if I could isolate the tone to one speaker indicating a bad speaker. When I turned the car on the radio worked normaly, no tone. Any idea what could cause this issue ? Thanks very much.
