Audio issue

[Sardog]

I have a 2020. Lariot with factory Nav and B&O audio system and have experienced a new issue. When I went to start the truck this morning both rear speakers and Subwoofer do not work at all. Only speakers that work are the front. Yesterday everything worked fine any suggestions on things to check.

Update
After further troubleshooting I realize it is only the tweeters And dash speaker that are working none of the doors are working.

I would see if fuses F5 and F28 in the BCM fuse panel under the dash are both good. They feed the amplifier. Also, check the connectors to the amplifier behind the rear seat.

I will check them but even weirder is after I came back to the truck after about 2 hours of being shut off it now works fine. When the problem was present I did try multiple resets of head unit and restarted truck. So I am at a loss. Seems to be working now though so whatever.

Was it abnormally cold or rainy that day by chance? I had some weird speaker issues along with others on this forum when it’s bad weather. My driver side b&o speaker will sound busted sometimes but only when it’s cold and raining.
