I wired everything and installed in direction of current flow I suppose. First 2x 4ga hot leads.
There was this nice space between the battery and box for the ANL fuse blocks
Both Wires In.
I could have used a single 0 gauge but i like to keep it seperate and color code everything so make diagnosing problems simpler in the future.
I won't go into detail about the power wire routing, I used the same boot everyone does. there are a ton of threads. I pulled up the floor molding and routed it under the carpet with some distance, so i could rout the speaker wire through the holes in the clips and keep some distance between them.
