Intermittent Radio - Back Speakers

So, the radio comes and goes on my 99 GTP, factory delco still in place.

The long and short of it: If it's a warm, dry day, they work. As soon as it cools off in the evening, no speakers in the rear.:banghead: The fronts work just fine.

Should I be looking at wiring, or has anyone run into this with the factory unit itself?

Your Pal,

Mr. C

Sounds like another speaker issue.

Do you have the bose system?

Also could be cold solder joints in the radio it self, which I think is more likely. The reasoning behind this is due to the fact is that it does work when the temperature is warm, but as soon it cools off the speakers quit working. It is also possible that the speakers have cold solder joints and this would also have the same effect with the temperature changes. Or if the system has a separate amp for the rear speakers that could also be the problem.
