Connect a subwoofer via speaker wire?

[sean67854]

When I had my house built, one of the option was a home theater prewire. I told them what I wanted, but I forgot to include something for the subwoofer. It turns out that they installed more wiring than I actually need for my surround speakers (they put in 2 2 strand wires and 2 4 strand wires) So even I could theoretically go all the way to 8.1 and still have a pair free. My subwoofer is not an extremely high quality affair, it is a JBL that came in a package with 5 sattellite speakers. Would it be possible to adapt the wiring in the wall to an RCA connection and use that for th sub connection?

No, your subwoofer is a line level signal and is designed to be sent down a shielded cable with RCA terminations. You could always do another run of coax yourself (RG-6 coax is cheap), or you can just purchase a pre-terminated cable and run it out of wall. But no, this will not work for your subwoofer.

You will need to run a new cable for the subwoofer

You can run inside or outside the wall (or ceiling if possible). Fairly easy run since you only have to pull one cable to each location you want a powered subwoofer.
