Yeah unless you plan on upgrading to bigger and better things in excess of 2500-3000w, in which case just spend the extra and get the OFC now. I like to do big wire for my big 3, personally. The run in my car is like 5ft so I can spend the extra on big stuff and it isn't a problem. I would get some 2/0 welding if I were you, you can get some used for like $3 a foot and it's some great stuff.
