Main power should be on a relay. You can use a fuse for the mains but depending on the system you may need a pretty big fuse. Again i would go with the stereo install type 50-100 amp fuse. At 100 amp it could still badly burn wires but a dead short will pop it instantly.

Also be sure to cover the wires with shrink wrap and a loom. And run the under the car inside the frame rail tied every 12 inches with zip ties or bolted down insulated clamp. Make sure it does not run thru any hole that is not covered by a groumet.
Ok I'm going to run a 2 Gauge cable for the starter. But couldn't you put a fuse back by the battery inline; because we never plan on a wire shorting out, other wise we wouldn't need fuses. Also what size wire should I use for the wire to the alternator??
