the closer the fuse it to the source, the more wire it protects. example: if you put the fuse at the jack, if the wire before it shorts, there will be no protection for that. if you want to overdo things put a higher rated fuse at the beginning at the wire and a lower rated fuse near the jack, the lower one SHOULD always blow first when protecting the jack.
