Brian,
Wiring up an amp is fairly simple, here's what you will probably needbased on the info you've provided so far:
Power Cable - If you plan on upgrading in the future, 4AWG is called for, but it's expensive. If you never plan on upgrading, get 8AWG wire, that should be good for you.
Cable Connections - Basically a battery clamp and connnections to make for a clean connection without a bunch of frayed wires an such.
Run the wire from the + battery terminal to the trunk. Connect it to the + on the amp. Now run more power wire from the - onthe amp to a ground spot on the car, I used the bolt on the seatbelt reel. Finally, run the remote wire from the amp to the back of the HU so the amp only turns on when the car is on.
Wiring the sub is the same as wiring a speaker.
