I recently noticed that the rear speakers and subwoofer in my Edge ST weren’t working. At most, it sounded similar to when an old iPhone wasn’t plugged in all the way to an AUX cord. both the radio, and apple car play audio had this effect. I master reset my sync system and am now in the process of updating my car over Wifi. any tips from anyone would be greatly appreciated. I’m assuming it might be a fuse issue, but I’m not able to figure out which fuse or fuses to replace. thanks
