I'm sorry, but you aren't being very intelligent over this. You need to read over basic electric principles.
Attempting to pull 150+ amps (2000 watts off of 12-13 volts) through 5 gauge wire is going to fry the wire. It will blow the fuses (if you have any), melt the wires, and possibly cause a fire in the car.
Trust me when I say take the **** time.
Also, Eclipse subs are fairly nice, I'd much rather have one of them than yours. Kicker subs do not sound good. The prefab kicker ported box is NOT custom. It's a pos that needs to be burned. I don't care that your in high school, while I was in high school, two jobs, a girlfriend, and more AP classes than I could count, family troubles, I managed time to put together an IB setup involving cutting up the rear of my trunk. I know how it is, you have time, you're just lazy and spend the time on a forum instead of doing it when you can. Then you get busy and use it as an excuse.
