About two years ago, I bought new speakers for the rear of my Volare. I have a radio out of a 94 plymouth van. The right speaker was getting to where it would constantly have a bad fuzz/buzz sound anytime it was on, so I replaced it with a new speaker, but now the new one after one week is doing nearly the same thing. The first 5-10 seconds the radio is on its fine, but then the right speaker starts the fuzzy sound. Shut it off and turn it on again and its usually fine until you hit a rumble strip or bumps in the road, and its only the right speaker... any ideas? Thanks

Swap the left and right rear wires to see if the problem follows the radio channel.
