I'm going to be running 2000 watts constant at 1 ohm to my btl and i was wondering what gauge wire i need to use? I'm guessing 1 gauge but i rather be safe than sorry.

You could pick up some 2/0 welding wire. Also look into a secondary battery and maybe a new under the hood battery (depending on what's in there now). Might as well do the big3 too!
