The answer depends on the wire size going to/from the fuse panel. Likely it is large enough to handle the load but you should confirm. On my boats, I typically bypass the factory fuse panel for the electronics and run dedicated 10 awg (or larger) wire from the main breaker to a seperate fuse panel.
Thalweg87 has been a great resource for me on wiring and electronics with my Ranger.
Whatever he recommends, I would go with.
