For power, I have a Optima Yellowtop up under the hood, upgraded the big 3 (4awg for now, 1/0 eventually), PG 1 Farad Cap, and a 1 Farad Digital Top Cap, 1/0 to capacitors, 4 and a little 8 to the RF amp). 14 gauge RF Power series speaker wire for audios, RF Power series RCA Interconnects, and 12 gauge speaker wire to subs.
