Xbox And Klipsch

does anyone know if there is a way to hook up a xbox to the klipsch promedia 2.1 speakers. like is there a adapter that takes the two sound rca cables and links it to a headphone connector that is used to hook the promedias up to my sound card?

Yeah, you can get something like that at radio shack for a couple bucks. I bought one there a few years ago for the exact same use.
