    Yes, hide the wires under the carpet.

    If you ground to the chassis, be sure to sand the area down to bare metal.

    Ten Gauge? If you are running a piece of Ten Gauge from the battery, all the way to the trunk as power wire, while it will basically be the simplest install in the history of the world, how much amperage are you actually trying to get out of it on the other side?

    I usually use ten gauge for turn-on wire, as it's actually the smallest wire I keep spools of that I really use for the cars. Anything smaller I use for other projects.

    The 10G wire came in an AMP starter kit so I know it will power it I just didn't have the 200 to blow on the good wire that is when I get out of school

    From the engine, its under the brake booster. From inside, its above the brake peddle. You will see bigger vacuum lines coming out of a circular rubber grommet, just pull the grommet up a little and push the 10g through.

    Ya I hooked it up; ran the power cable next to the speedo cable coming up from the trans and it fit fine. About to upgrade to a 0 once I get my check and run a split box under the dash for lights and any thing else that would need power.
