I second knukonceptz. When I was building custom vehicles I always used them. Best wire for the money, and they are a small local run business, not some mega corp. you can call them and talk to someone and they will box up your order and ship it out while your talking to them. They used to sponsor quite a few guys in our car club. They tended to be better on the price too, we would order 500 feet of 0 gauge wire for a single build. Their RCA cables are the bomb too

i use a local guy for stereo stuff..100' 14g monster..he charged me 25 bucks..
