Actually the white and gray are for the front speakers. The purple and green are for the rear. The reason for using the front speakers is to eliminate sub feedback in a car with speakers in the rear deck. That happens when the sub note hits it will push on the the rear speaker causing it to send a signal to the sub thus creating a feedback loop. Using the front speakers works because the sub won't push on those. However being a jeep who the hell cares what speaker gets used so go ahead and use the rears if ya want. Lol.
Also when installing an amp to a pioneer you must ground the amp, and make sure the radio is grounded before plugging in the RCAs to the pre outs. If you turn on the radio when the RCA is pugged in and the amp isn't grounded the amp will "search" for a ground which is the outside RCA prong then thru the radio. It can damage the radios outputs.
X2 on getting a new power kit for the amp. I rec bench prepping the amp which means wire the Amp and make it pretty then choose your mount location. There several bolts to mount to in the tub make sure you scrape the paint where you ground the wire to get good conductivity. Run your wires under the carpet or along the harness that's already there. Run the RCAs along with the power (some may disagree but the bass signal won't get interference IMHO and its a cleaner install) run the power wire thru the firewall (there are plenty of grommets to pick from) make sure the wire doesn't rub or hit any of the hot things in the engine bay and then hook up your power wire directly to the battery terminal. Keep the fuse out of the holder until you are all done JIC something gets messed up along the way. Now connect your remote wire to the blue wire with the white stripe if no white stripe then to the solid blue. Plug the RCAs in, put in your fuse, and don't turn it on. That's right don't turn it on until you set your amp to the correct settings. Now you can turn it on, lol.
Also with the subs wiring. If you have two normal 4ohm subs and a standard Mono block amp run your pos and neg from the sub to the port on both sides. Then use a jumper wire from the port 1 to port 2 pos to pos neg to neg then hook another wire from one of the ports to the terminal on the amp. If your amp has 2 terminals you can run one to one port and one to the other. In theory its still the same hookup. --Good luck!
