I have an unusual problem with my sound system and would like your input.
These are the 2 occasions and the symptoms that present itself. The 2 occasions are describe in A and B.
A. When I go for a 30+ minute drive, occasionally(perhaps 1 in 4 times), the sound system won't work at all after the restart of the engine. I have physically felt on the amp and it doesn't feel warm at all.
B. If it's cold out, example, colder than 55 degrees fahrenheit, the radio will not work.
The symptom:
1. The headunit will just display PORSCHE. Inserting a cd, ejecting a cd, ejecting the cd-cartridge under frunk, pressing fm, cd, am or any button on the radio does absolutely nothing. no sound.
2. The head unit will function perfectly fine, all buttons work, skipping track works, changing radio station work, but no sound.
I have an 03 Boxster S with Bose sound system.
