Have you looked at both ends very close, even under a magnifying glass. Sometimes the markings are very hard to see. But, with the "imported" equipment they don't always adhere to industry standards.
Speakers are made to be "throw away" units not repaired and thus not much, if any documentation or avenues for repair.
One other issue, if the fuse blew, that is supposed to be a safety item for other component failures and even possible fire. There's no guarantee that it's "just the fuse".
