Alternator whine

[adamw89_2000]

So when I have my radio on I get a bad alternator whine coming through my back passenger door speaker that gets louder as the engine revs up and quieter as rpms decrease. I bought the sut with already installed headrest monitors that are indvidual DVD players and have some type of generic gaming system built into them. Any clues on how to cure this? Thanks
