amp made a whistling noise

[murph 10+ year member]

My amp cut off and made a whistling noise and I had heard it doing this prior for a few days. I went and tested the power wire to see if it was sending power through it and it seemed to not being doing so. I then checked my inline fuse stinger maxi (i know i need to swap with anl fuse) and there was a strange bubble like look to some of the metal inside the fuse. I replaced it and everything works fine but not sure if this was caused by the amp or the fact my fuse is 100a and my amp puts out at least 1200 watts. Does this whistle sound mean anything?

I use knukoncept fuses and they work fine. The one time I've had a fuse pop it went right out instantly with no strange after effects

yeah no fuse pop it just had a strange look to it. It seems to be the cause but why would my amp whistle?

Probably low voltage causing it to operate poorly

btw by inline I meant maxi fuse it is not an anl fuse

voltage drop was down to 12.8 at it's lowest but I'm doing a big power upgrade in a few months so I will just deal with what is going on for now.
