Something like that but I'm sure mine is like 150amp fuse or something. I'm not sure if that will blow when you engage the starter. It will depend on the size of wire your running aswell (iirc I'm on 4awg subwoofer wire)
I didn't bother with an additional one, there is one located in the fuse box,
Most older cars that had the battery in the back didn't have a fuse near the battery, just insulate the cable well
