What wires are you using? you usually fuse to the wire.. so 0ga can usually accept up to 300amps or so.. but if you equipment only takes 150 then thats all you really need on there since you don't want anymore than that going to your amp anyways..so if you are going 0-4 ga if the 0ga has a 300a fuse on it the 4 ga will not carry that load.. so that fuse won't see that 300 til the wire melts down and gets to the fuse... so you would fuse to the 0 gauge... Now then if you had a 100a fuse on the 0 ga for some reason then it would be fine for the 4 ga as the 4 ga can handle that load and the fuse would go first get it..?</blockquote>
