get a wiring kit that is good up to like 1,000watts. that way when you wanna upgrade in the future you won't have to worry about wiring your car up again. you need power wire from batt. (probobly like 4guage) and ground to match, rca's from the headunit for each channel you're running a sub off, and the remote wire to turn on the amp. oh yeah, and speakerwire for each sub from each channel.
