MB Quart cross over problem

[rak_24540 10+ year member]

I have a PVL 5.25 set in kick panel, both of the tweeters stop working at same time. I can run power straight to tweeter and they work but not through the x-over that came with it. I can't imagine that both x-overs would mess up and the exact same time. I don't know what to do. Any ideas?

I haven't looked at the new PVL crossovers, but MB Quart used to have fuse shaped light bulbs in the Premium and Q line crossovers. The bulbs were used to protect the tweeters, so if the bulbs are blown the tweeters won't function through the crossovers.
