As usual, I concur with Fabrik. 4 Gauge should put you good for ~135 amps, go to 2 gauge if you're feeling frisky which should be good for ~180 amps.
Yeah I went to NAPA and order 2 gauge battery cable they supply. It was $4/ft which wasn't bad. It's the cable that is used to make up battery cables and not audio wire. I do have 4gauge audio wire I could use but I'll just save it for whatever I may need it for.
I'm leaning towards 2gauge just to make sure I am covered with the power in the car. Since I will be running other electronics in the car.
