I just recieved my 950/770combo about 3 hours ago. I have a question that might sound stupid to some but here goes. I have a Klipsch powered sub with speaker connectors on the back of it. I had this hooked up to a Yamaha reciever for 6 years with speaker wire to the reciever speaker inputs , and then wire from the sub to the speakers. I see I've got one RCA out put from the 950 to the sub.Can any one suggest what kind of cable I can connect to the Klipsch 200w powered sub?
