2004 Silverado 1500 Bose Sound System Stops Working In Cold Weather

[04rado1500]

Title pretty much says it all. In temps lower than about -4 or -5° C (≈ 25° F) I get no sound out of my speakers. System is entirely stock except an aftermarket stereo deck (bought the module to keep steering wheel controls etc.) head unit lights up and my phone can Bluetooth to it but no sound except for a clicking noise from the speakers. From what I’ve seen it’s likely a dead amp, seems pretty common. Is there any information available about the factory bose amp or is there an amp available to buy that is equivalent to the factory Bose that I can replace it with? Not looking to add a big sound system in the truck any time soon.
