This is a used fused JL Audio power cable block. Have a generic 100 Amp fuse on it. Its for 0/2 gauge wire. Any questions feel free to message me. Thanks.
I think the way you are phrasing the question is a little wrong. If you plan to make 5000 watts, based on a 12V system, you would need, roughly, a 400 amp alternator. Most cars come stock with about a 100-140 amp alternator.I have 5000 watts what size alternator I need to go with
