Zip cord is NOT good for ANY application, because it is inherently 
susceptible to RFI. TWISTED PAIR is FAR better, because it inherently 
rejects interference from low audio frequencies to at least VHF. In the 
last few years, I've been replacing more of my DC wiring with twisted 
pair. I make it by putting black and white stranded THHN in a drill, the 
other end in a vise, and twisting.
