I wonder if we're misunderstanding each other ... I am not suggesting you dual-use your high voltage romex and also send audio signals on it ... I am suggesti

  Would it? You’re allowed to use chapter 3 wiring methods for audio, but two speaker circuits is four “ungrounded conductors.” Red and black are fine for this purpose. I’m not so sure about white and bare.

    Can you tape the ends red and black in this case? I thought there were some provisions for options there in case you had some super heavy cable but wrong color

      The rules are different for <=4 AWG wires versus smaller wires. I don’t know why.

        You can use tape or heat-shrink to re-identify a wire if its 4 AWG or greater or if it's part of a multiconductor cable (which NM-B is). The reason for the 4 AWG rule is probably an economic one. Having spools of larger conductor cables in a variety of colors is not inexpensive. Allowing the reidentification seems reasonable, though I'd probably argue the cutoff could be thinner than 4. The multi-conductor cable exception is a practical [and economic] one. You might not be able to get multi-conductor cable assemblies with the exact color coding you need.

        Ahh - makes sense - high amp cables get insanely expensive
