I currently connect my DVD player to an LCD projector using RCA cables. The speakers on the LCD projector are no good and I would like to connect external speakers, like those cheap little computer speakers. The cords on the speakers have a USB end and a light green end. Nothing on the LCD projector is USB or light green--just the standard cable and RCA jacks. Is it possible to connect the speakers I have to the LCD projector? If so, can anyone help me figure out how, maybe draw a little diagram or something?
