The standard cable is still there too, mate.
So its got what ever that is (smaller than 8awg standard?), plus the 8 awg i have run.

8 awg audio will do 80a over 30ft, or so i am led to believe?
could be bollocks, used an online calculator to figure that out?

Whatever it is, its still got more than ford gave it .
I seem to be getting 13.8v at the alternator now.
