I use Stinger's high end stuff (HPM series) for power, ground, distribution, battery terminals, etc. I use JL's blue wires for RCAs, and for speaker wire I think I have some of both. Honestly the JL RCAs are better than many I have used before, but they could still be improved upon. I want something thick and beefy and well-shielded (they are) that doesn't have the screw-type heads (they come loose easily) and I want something tough enough where I could pull it off of the amp (or whatever) by pulling the cable itself and not having to get my fat fingers squeezed just right around the slippery bare metal end piece. But really, they are good wires. I just dig the ones I have in my home that have plastic around the ends and the whole thing is integrated into the wire so you can pull on the cable itself with confidence.
