A while back I bought a Behringer Feedback Destroyer, which required the addition of a short run mono RCA interconnect from the receiver to the BFD. I bought an el cheapo Rat Shack one, and not even a good cheap one, but a cheap cheap one (not much shielding, looks pretty cheap in construction), which I thought would be fine for a short run.
Now just recently I purchased a new TV, which after upgrading to component cables, and swapping a few other things, means I now have a pretty decent composite video cable no longer being used at all. It occured to me that this composite video cable is just a gussied up RCA mono interconnect (extra shielding, 75 Ohm something or other...). So, I should be able to use this cable as the connection between my receiver and BFD, correct? There's nothing I'm missing that would make this a poor choice to carry an LFE channel, is there? I figure better to have the $2 cable collecting dust and put the $25 one to use.
