fuse/electircal system diagnosis

[loudlittlefvkus 10+ year member]

Okay, so today my subs stopped working. the first thing i did was check my fuse. a 120 amp fuse, going to a jl audio 1000/1 slash v2 amp. the fuse was kind of corroded, looked like it was burnt a little on one end (ill post pictures when my phone charges) but the fuse was not blown. then i was wondering, because i think i have a bad ground, which im about to go check out, that was the cause. can a bad ground cause that? i also had a little extra 8 gauge wire grounded from my battery to the chassis if that makes a difference in this. i went back to check my ground, and my RCAs fell loose. could that have caused the problem too? i checked my power wire and there are no breaks or melting, like i said ill post pictures of it all when my phone charges. anyone have any ideas why this might have happened?

Update, my grounding is completly corroded, could this be a reason for my problem?

Yes. Fix that, then report back. Any corrosion is no bueno.

Im building a new box starting friday so i took my system out for now until then, and im going to do a much cleaner install. that was the first install i did last fall, and over the winter i learned a lot. so i think it will be better the second time around. so my grounding was probably the issue with the fuse? i just took pictures of the fuse and ground, uploading them now

as cheap as fuse holders are I'd replace it and the fuse. oil and sweat from your hands will accelerate corrosion especially on copper and thinly plated metals

replace the fuse/block all together. for the ground, make sure when u get the new system set up, that the wire is touching bare metal. make sure its not loose either.

Any fuse blocks and holders youd recomend? And I read the sticky on grounding and im completly replacing it with new ring terminals and everything too

wal mart sells fuse blocks for about 10 bucks. they only come with 40 and 80 amp fuses tho. or try amazon. there roughly 5-10 bucks
