I run 10ga to my subs, and 14ga to all other speakers.I look for the highest thread count on most of my wiring.For a single vehicle I use/ buy a 1ooft spool for the speakers, and approx 25ft for subs,.Jl wire is pretty good, Stinger.Alot of people swear byKnutz I think it is.Yet, If your not going to compete,Just make sure you get a good thread count,I like to use copper also.//content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif
