The other two units are already installed and are sharing the power wire already there, so I thought I'd run 8 Guage wire from the battery into the car, so I can use that to hook up power to the EMPEG using it's wiring loom, this will be fused with a 3amp glass fuse, don't know if that is the correct fuse and rating though,
but since it says in the manual the EMPEG is fused 3A internally, I'd use the same rating.

Also I thought 8 Guage would be ok, cause looking at all the other wires in there, I would'nt want to run anything thinner, in case of it shorting, or blowing something?
