brent245,

On grounding part of your question: Keep ground wire short as possible. Ground should be made to metal. (Use sandpaper to remove paint and primer till you see metal. Make sure ground wire is tight both at amp and at chase point.)

Good Luck,
Sandman

PS. if you are running a 1/O power kit, that means you are running a big amp, make sure the power draw is not going to take more current then your Alt. can provide.
