Well i bought the system used from somebody saying they were missing one cord that goes from the system to the computer.Well its missing that,the din cord and the dc cord from the volume base to the sub.Now the mini stereo plug and the din cord i found on the klipsch website but i cant find the dc cord.Ive looked online at several websites and looked on ebay and havent found it.Some help would be appreciated.Dont know much about stereo equipment but the volume base says a DC 7V in  800 ma on it.It goes from the volume base to the subwoofer and then the sub has an ac cord that plugs into the wall.
