I want to connect Ipod to satellite speakers

This stuff is NOT in my realm of knowledge so I am seeking some xpert help. I simply want to be able to connect my iPod to a pair of Boston Acoustics Micro 120X speakers. The cable I currently use to connect the iPod to some old bookshelf speakers I have is male RCA on both ends. Of course the Boston speakers have no place to plug in an RCA connector, they have 5-way binding posts. can anyone tell me how to accomplish this or am I out-of-luck and unable to use the Boston speakers? Thanks! :confused:
