Grrr. look at this site for wire too. cardomain.com If you think that your gonna expand later, weeks, month, even a year down the road make sure you at least buy 4gg wire. I started with 2gg wire just cause I knew later I would want to upgrade. When ya run your power wire its best to run it once and not have to go back untill the wire goes bad. Stay away from 8gg its just not worth the money unless its just running from a distribution point.
