I recently ordered a 50ft spool of 1/0 awg CCA power wire to do 4 runs in my 2000 Astro van. It arrived 3 days after I ordered it with free shipping. The wire is very flexible true gauge and as attractive as wire can be. I had previously ordered 8 awg speaker wire and was very impressed with it so when the need for more 0 awg came up I decided to go with Sky High. I'm very glad I did Sky High Car Audio cables are top quality. I will be purchasing SHCA for all of my cable needs from now on.
Ordered a 50ft spool of pink cable. I must say I love it! Really easy to work with. So far doing great on my install. And in the same state. Can't beat that. Recommend highly.
