2 gauge runing from starter to battery and grounds.
running 2 amps, WS SYN 6 and the stock clarion that runs the sub and boat speakers.
Are you asking about the two 'field wires' between the alternator & perko?
I don't think it really matters much, there will not really be any amperage passing thru them, just voltage.
I think I used 16 gauge on mine.
