  • Main harness power and ground leads

    On page 15 note 25. it states that all power and ground leads must connect directly to the battery. How are the folks with trunk mounted batteries handling the wiring?

    "If necessary, the power and ground leads may be extended to reach the battery. However, the use of 12 gauge wire or larger is required. WARNING: All power and ground leads must connect directly to the battery."

    Per the PF4 instructions..
    Don't get too caught up in the numbers.
    Just give the Engine what it wants &
    Let the numbers be what they are.

        We have a couple of people here with rear mounted batteries.....and they have issues.
        If you are not a expert in wiring. You might have issues too.

        Can it be done? Yes.

        Can any one help you "here" if you have issues? You won't know, till you ask.

                Make sure you run both pos & neg to the battery. Some have tried pos only, and there are problems.

                    Smallest speaker wire in my car is 8 AWG Cable

                    Punch line: Music is AC voltage. So the DC conversion means I'm using actually using a little larger the 6 AWG Cable.

                    Also SAE wire ( stuff used on automobiles ) is around 12% smaller then the AWG Cable I use.
