Why does the sound go "in and out" in my car?

All of the sound goes in and out of the car. Sometimes I can still hear the radio, but it seems to only come out of a couple of speakers, and is very "scratchy" sounding.

Check the individual speaker wire and cable connections at each speaker - as the first step. Next, check the common speaker wire connections from the stereo unit to the pairs of speakers.
