Intermittent Radio

[FrancescoVernava]

Got a very temperamental radio. Doesn't like the cold. If you don't leave it turned on when you turn the car off, it doesn't like to work when you turn it back on. Power to the radio, just no sound coming out. Any thoughts? Loose connection to the sub perhaps? It's the Harmon Kardon system. When it works, it's superb. Just don't like it being temperamental

Sometimes if it's not working, and I drop the roof or mess with a window or something, it starts working again. There's absolutely no rhyme or reason to it. But more often than not, it's not working

Have something similar with my 2003 with the OEM Carver 10 speaker setup. Only occurs during the winter. playing with the window switches while the rear defroster is turned on gets the audio running for a while. Never bothered investigating yet as i enjoy the sound of the car more than my music
