how big of a fuse do i need?

[jaydog13]

I am trying to figure out what size fuse i need for my system. Looking over the web i've heard that you need the same size fuse as the current of each amp or the fuse/s that are on the amp. I have 2 30awg fuses on one amp and 1 50awg fuse on another- so should i use a 110 size fuse? I was running only a 60 glass fuse before, is that bad?

It's not bad to run a smaller fuse. You only are wrong if the fuse is too big. If you're not blowing the 60A fue then it's big enough for your purposes.

AWG is a wire size not a fuse rating, BTW.

if you blow a 60 fuse with that setup then go bigger, but you are suppose to fuse to the size of your wire, not to the current your amp draws. what size wire are you running?

You can fuse to whatever you want up to the size of the wire. You don't have to install a 300A fuse for 1/0 or a 125A for 4ga, you can go smaller than that if you don't need it, but you can't go bigger.
