much better. start off with 4 gauge wire since thats what your amp can take. you can always get bigger wire and purchase a wire reducer or trim your wire to fit, but for now lets say 4 gauge. you can find decent wire "kits" to fit your needs that come with everything needed to install an amplifier, including RCA's, remote wire, power, ground. building your own box will be best if your inclined to do so. if not you could go to a local audio shop and they can build you one to specs of your woofers, but, thatll probably cost you a pretty penny. id build my own even if i wasnt so great. youll learn as you go. but now your gonna have to elaborate on what else you want info about when you say "EVERTHING".
