Answer:

The reason you need a fuse on the power cable is that if the power wire gets shorted to chassis metal, and you don't have a fuse near the battery, the wire will overheat. When it overheats, it will scorch or ignite anything next to it. Any wire connected to the battery, no matter how large, needs to have a properly rated fuse installed as close to the battery connection as possible.
fuse will stop it from melting if it or something shorts out so really its just smarter to yes you should
It doesn't matter if its 350 watts or 35 watts. You need a fuse.
look at the fuses on the back of the amp, total those up and there's the fuse size you will need to use on your power wire.
