Thanks. I thought about checking there, but I'm a little unsure about what I should be buying. Since each satellite speaker has a monophonic signal coming out of its RCA cable, I assume I'd need a mono speaker cable with an RCA interface and maybe a coupler to extend connect each rear surround speaker to the extension cable. However, the only cables I see not labeled as stereo say "audio patch cable" or "phono cable." Will this carry a speaker signal (i.e. is this what I should be getting)?
One last thing, the ones that I've seen over 25' are 18 or 24 gauge. Shouldn't I be looking for at least 16 gauge or 12 gauge if possible (someone told me 12 gauge is more appropriate for long cable runs).
Here's an example
