Typically you're just fusing the wire to protect from a short to ground (cable punctured or comes loose in the car). Not sure if its different in these super high power situations.

Depends on what you want to fuse for.  Are you fusing to prevent overcurrent supply to the amplifiers?  Are you fusing to prevent a fire in case of a short?  Are you fusing due to class rules?

Then fuse to the current rating of the cable.
