Within a few minutes of driving, suddenly a loud BOOM that my initial thought was my window was shot out or heat shattered. Pulled over and checked windows and nothing, all the while the original "BOOM" turned into cracking sound (video). Realized that it was from all speakers. Turned audio off and sound continued. Rebooted sync 4 and sound continued when system rebooted. Pulled over, turned off ignition, open door, waited and sound continued. Restarted truck and changed audio source to XM - work fine, then cycled through all audio sources and worked as designed. Anyone have thoughts of WTF just happened?
