You should have an Auxilliary input on the back of the Bose, either RCA jacks or a 3.5mm "headphone" jack. Depending on what type it is, look for a cable with a 3.5mm plug for the iPod side, and either RCA or 3.5mm for the other side. You could also use a dock for the iPod, but you'd still need a cable to connect to the Bose.
