How do you wire altec lansing acs410 speakers to PC?

If this is the same acs 410 i have...i have the subwoofer running the power...it plugs into the wall...and a purple and power wire running from the sub to the smaller speakers (satellites). then a tan wire connecting the two satellites. Then another 1/8 " headphone style jack going from the main satellite's "A" hookup to the computers green sound out jack. If you don't have the sub setup with this...and don't have a wall power pack...you will have to track one down...or the sub unit. BTW i love these...even though they are big...they sound nice. It can separate dolby sounds out the sides if you turn the surround knob on. When off it works like a normal pair of speakers. With my sub in the corner...it puts out some nice bass if you don't push it too hard.
