you can get it down to 6v using a voltage divider network. If the purpose of this is to turn on a ford factory amp without popping 6v will still work so u can try it.

To do this simply take your source wire, put a resistor in it(any size) then put a second resistor of the same size in series then ground the other end. Then run a wire out of in between the 2 resistors. This wire from in between the 2 resistors will be half the voltage of your source wire.
