Moving audio gear in sub zero temperatures


Need to transport my audio gear (turntable. Tube amp, speakers etc on an overnight trip in freezing weather. If they are in a dry vehicle that is parked outside for a night, can it damage anything?

They should be fine, but when you bring it inside, leave it off for 24 hours to ensure any condensation clears first.
I found this:
Samsung Plasma TVs can be stored at temperatures ranging from -4 °F to 113 °F (-20 °C to 45 °C). Storing a Samsung Plasma TV in an environment with temperatures outside this temperature range can damage the TV, even if it's not in use.
And this:
Cold temperatures will do no damage to plasma TVs until they dip below freezing. The cold itself doesn't hurt a TV, which is why it can be transported and stored in freezing temperatures. But if you take a cold TV indoors and immediately turn it on, its electronic components can suffer irreversible damage.
Oh, and don’t slip on the ice and drop it.
Properly boxed up the inside temperature is going to be higher than ambient. 
I have a bunch of stuff that was submerged in liquid nitrogen for a week. So no, I don't think overnight in a car is a problem.
