if i use 6ga wire would a 30 amp fuse work? my alternator is stock 318 swinger

30 is rarely enough. Get into the "audio freeks" depts and look for those big fuses, one type is called a "maxi fuse."

According to this page

http://www.offroaders.com/technical/12-volt-wiring-tech-gauge-to-amps/
6ga at 4-7 ft is about 125 amps capacity. If you think your alternator is below 50 I'd use about a 50A fuse.

This chart here might be better but harder for me to read
