Melted In-line fuse?

[06goat 10+ year member]

Ok I have a 400rms amp powered by 8 guage wiring. Well the amp shut off yesterday so I did some troubleshooting. Found out that the In-line fuse was melted? Not the actual fuse.. the entire holder. How the HELL does this happen? I can only unscrew one side. The other side is melted to shit. When I unscrewed it, the fuse fell out. The metal part and not the plastic outer part of the actual fuse. So it looked burnt up or melted. So what happened?

something grounded out

check all wire ends and look for cuts/frays

not entirely true, if something grounded out the fuse would be blown but it may have no melted the case. where is it at under your hood? my friend had one to close to a belt or some type of equipment that produced alot of heat under a hood causing it to melt it over time.

Well wouldnt it have been warm? I checked it like 4 minutes after it shut off. And i dont think it would melt the entire plastic. Ill still check the wire though.

Also how bad would it be to run it without that fuse?

could have blown the fuse but didn't break the circuit until it melted the whole shit

i had an 80a inline round fuse running in 8g power wire back to an MTX2300X lol... I have it in my drawer still, its completely melted and bubbled. Fire hazard like whoa! Fuse held up though.

Well all the wiring came in a kit. So I dont think its too small of a fuse for the system.

So Should i just get another In-line fuse? Or a new wiring kit? I kinda want to get 1/0 guage. Just to have room to upgrade.

Sorry for DP but how bad would it be to run it without that fuse?

that wires probably taking a load?

i was running a 4 guage to my entire system, cause i dindt want to rewire a 0/1 guage and i melted 2 of them fuses

so i changed to a circuit breaker, and separated component and sub amp from batt

well you risk blowing up your battery, or severely hurting your electrical. you also will have a fire hazard no matter how you look at it then.
