Amp Fuse Question

[GuysIGotThis]

Hey guys,

I just got a new sub and both my 50 amp fuses blew on my amp today.

My amp is 1000 RMS

My sub is 1200 RMS

Would that cause it to blow?

Also noob move but my negative was a little loose. So I'm thinking that is more likely my issue.

w/o brand/model info it's about impossible to help you.

A minor difference in power rating isn't the problem.

What could be the problem is the impedance of your sub is too low for the amp. That usually triggers protection, but could also blow the fuse. W/o brand/model -- who knows??
