I'm sure this is a stupid question, but this is something I have never come across. Just moved into our new house that was wired for 5.1 surround sound. The five speakers all had the red/black wires, no problems there. However, the wire for the subwoofer is actually a thick black cable wire, just like what is used for video. So . . . how the heck do I connect what looks like a video cable to my sub and receiver. Thanks for your help.
5.1 receiver will have an RCA jack for sub-woofer out. Powered sub will have an RCA jack for subwoofer in. If you have a receiver without a dedicated sub out, or a "passive" subwoofer with only speaker wire terminals, then your out of luck.
I understand that (and that's how it is currently hooked up). However, the builder installed a cable to hook up the sub in the back of the room. Therefore, there is a cable coming out of the wall in the front of the room and at the rear of the room. This cable is the black video type cable with the copper wire in the middle when you strip it. How do I connect this to the RCA jacks in the Sub and the Receiver? Thanks.
By the way, the sub is a new Polk, and the Receiver is a new JVC, so both are fairly advanced.
