For your big 3 upgrade, you don't NEED to add fuses anywhere. Why do you think the wires need any extra protection? The biggest danger is usually the alt > batt. wire falling into the cooling fan or melting across a hot exhaust header. Follow the factory wiring and use lots of zipties and you'll be fine.
Now, if you're talking about the power wire that lead aft to supply your amp rack. distro block, then yeah, you need some sort of protection. I like CB's over a fuse 'cuz they allow you to cut power to the system if you wanna futz around with changing the configuration.
