Stinger SGW516 Stinger 50 feet 16 Guage Twisted Speaker Wire Roll
I'll start this off by saying I think it was fairly reasonably priced. It didn't always come out neatly when I stripped back the clear outer layer, but other than that I'm very satisfied. I have it from my amp in the rear of my extended cab, to both my door speakers, and my rears. Constant 75 watts to all speakers, 0 ground loop noise, couldn't be happier.
