Speaker Problum need help

[Sesleeper]

I have a 99 grand prix se and every time it gets cold outside/gets wet outside, my back speakers stop working, but if it's hot outside then they work. Every site I go to says it's an amp problum, but I can't find it. I have checked all my ground wires and there brand new (no rust). What should I do with out buying new speakers.

Its the speakers themselves. They die and will only work in warm weather. Its a common problem. Just buy a set of 6x9's and have them installed or do them yourself. You will have to take out the backseat, but thats easier than it sounds. Should be about an hour start to finish.
