d2b optic fiber issues 2002 command

[budiu22]

Basically. if i leave the car outside my garage all night in the freezing weather all sound in the car stops untill it warms back up. my amp is working great, absolutely no sound from speaks, i run d2b wake up call tests and it says everything is connected and all things are check marked, no errors or codes either. system reset does not work either. i tested for this 5 different times and it only seems to stop working when i leave the car in freeezing cold weather over night. No snow or rain involved. and then when the car warms up in my garage or in direct sun light it magically works and sound comes bakc like nothing ever happened. i read online in a few websites that Fiber optic systems do not like freezing weather and thats when i first started doing the tests. anyone ever experience this?
