It appears I have a blown speaker on my '03 Aviator.

There is a loud crackling sound coming out of the speakers, I think, on my 03 Aviator. The radio works very intermittently. The crackling sound comes out out whether the radio is on or off, volume up or down. It's very loud. Any suggestions?

Is this from one speaker or both?
