I'm trying to run my sub to the back of my living room approximately 25ft. Where can I buy it that long or can I make it myself using coax cable. If I can, what kind of coax. Thanks.
RG6 coax will work fine. I have somewhere around a 25' RG6 coax cable that I did myself for my SVS. No problems at all, just make sure you get the ends crimped on correctly.
I like the Monster sub cables for the flexibility, neutral color, and what appears to be very good construction. And an easy cable to snake along walls.
