2006- XC70
I keep having this problem when the temps drop: I installed a Kenwood receiver last year...clean install. Since the car was 'new to me' at the time, I haven't a clue if the following happened with the orig radio, as I installed the radio as soon as I got the car. When the temps drop below 32F, when you start the car, the radio does not come on. I have to go the fuse panel on the side of the dash and remove and re-install fuse #10...a 20A fuse that says "Audio". The fuse is not blown, but taking it out and putting it back in solves the problem. I did this all last winter whenever the car was cold...drag.
Any clues?

Is it any different if you just turn the key to Pos I (no ignition or starter crank) and turn the radio on?

What if you start the engine first, let it run a minute with no heater (interior still cold), THEN turn the radio on?

How old is the battery?

Have you checked for voltage in the power wiring between the fuse and the radio/amplifier when it's cold?
