just get a distro block and thats it. and make sure you get big enought power/grounds. Do your amps have rca outputs ? if not maybe some rca splitters if you do not have 2 pre-amp outs on your head unit. What kind of amps are you running?
honestly dude if you don't tell us how much rms your running then we can't tell you what you will need. but for the most part you'll probably need about remote wire, 20-25ft of power wire, 6ft ground wire(at max), a distribution block, an inline fuse holder & fuse, short thing of rca cable for strapping amps, and of course speaker wire.
