My opinion is, wire is wire, RCA's are very important and the 8-gauge wiring kit from raptor that I bought were pretty good, besides the copper innerconnects. I think they make very good cheap wiring kits. Something funny though I noticed, on the back of the packaing for the wire it said something like" Made in China with strict raptor requirements" thought it was pretty funny....and oh yeah there insulated nicely, oxygen free plastic, and there insulated thick, and the strand counts are correct.
