I have a single fuse under the hood close to that battery and I have wire ram from it directly to the back. I was gonna run that wire into that fuse block into my 2nd battery, and a wire coming from my 2nd battery into the fuse block into my amp! Seems like that was what I needed

I’m stumped as it can get I tried to order 2 single fuse block to add to the back of my Tahoe for my 2nd battery and amp and I can’t seem to figure out how to wire it being as one side of the post connects so I feel like it would bypass the dude for either the amp or the wire coming from my main battery. This is what I have if anybody could help and point me in the right direction I’d appreciate it.
