Let me first clarify that I am a girl so I have no idea what is going on with these speakers I have - so if I am asking a dumb question give me some grace cause like I said, "no idea what is going on." With that out of the way I have a pair/set of Logitech Z 560 speakers, it consists of one subwoofer and 4 speakers. All the wire coming from the speakers are present and I know how to hook them into the subwoofer. The subwoofer has a power cord coming out of it and. . . that's the end of what is has. There is no way to plug this thing into anything other than the wall. I need to figure out how to make this thing either hook up to a computer again (and I have a mac) or to an ipod - if any of those things are possible. The person who I got the speakers from said that the piece that I need is not sold by Logitech anymore and won't help me fix this cause he'd rather play computer games. Thanks!! This is what it looks like. . . though I don't have the controller thingie.
