I went to an awesome electronics store here and got some cable.
5 ft of 1666 strand black StreetWires 4 gauge cable and 8 ends, enough for 4 wires. I'm going to take measurements soon and install them. My car isnt running yet cuz I am still building it, but I will take some pics and write about it once they are on and it's running!
Also, the wires/connectors were ~$30.
