You will need at least 2 gauge, if not 1/0 GA, power wire. I also suggest upgrading the big 3. If you can, return the cap, you don't need it. Also, if you can, return the audiobahn sub, it is garbage. You might want to put some bracing in that box too. You will need a big sub to take full power from that amp, as Kicker under-rates their amps, especially the higher powered ones. I would look into a 12" L7 or equivalent.
