I've had some success with a thirty dollar computer speaker amp setup--you know, the things you can plug into your computer to enhance your video game play and so on. I bought these at Big Lots, which offers some cheep electronics. One year I used two and the next year used only one, to simplify. I taped some black plastic trash bags over the speakers so they wouldn't look like anything (not that they were high-end or expensive in the first place). A battery-operated mp3 player with my own stereo audio track was plugged into this stuff.
Many people use much nicer and more elaborate systems, which always impresses me! In my case, I often have to set the sound up fast, so portability and simplicity tends to be useful.
