I really appreciated the help. I have a 4 conductor wire running through a wall going from an amplifier to another room where I am considering mounting a speaker. Problem is, the wire is of low gauge, something around 18 gauge, for about a 50 foot run. I know it's very unideal, but I was wondering if creating two pairs of wires in parallel would help at least a bit with sound quality considering the wire is, for lack of better term, well, shit. I've included a (very crude) illustration of the four wires just in case I didn't explain this properly. My question is, is this worth doing in my situation?
