I have searched these forums and simply want to clarify something. Can any cable that says "RCA" be used as subwoofer cable? What I mean is, you go to different sites and one says, "RCA subwoofer cable," the next says, "RCA audio cable," and the next says, "RCA video cable," and I just want to make sure any one of them could be used as a sub cable. The reason I ask is I will need a 50' sub cable and want one that is shielded. Parts Express does not carry a 50' Dayton sub cable or any 50' RCA cable. I found this 50' cable and want to make sure I can use it as a sub cable.

Also, I posted earlier about speaker wire outside here. Does anyone know if I would have any problems running the sub cable outside as well?
