1. The Power/RCA myth has been busted. See this thread...
2. No problem at all running power by speaker.

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

Whew! Just read the related threat. I had to dig WAAAAAY deep into my electronics training to keep up. Every day I find another reason to be happy that I joined this forum!

Now I need to go and re-read that thread to help it soak in.

Speaker is after the amplification, which is the important difference here.  In the case where speaker wire is used for the preamp signal, it should be twisted pair cable and well away from power wires (as in the case of wiring to a LOC).

Myth might have been busted, but still separate the power and signal wires.  posted_image

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.
