I'm not sure if this needs to go here or in Technical, but I see a lot of people pushing "speaker cable" for installs, though I have a LOT of THHN electrical wire. I have also seen a video where the guy tested several brands of amp power cable against welding cable. Surprisingly, the "cheaper brands" (including that he got from Wally World, Scosche I belive) come out on top. What would be the difference in sound quality though? Any?
