8 Gauge and 100 amp Maxi fuse?

[TheGreatMonkey 10+ year member]

I have a Phoenix Gold 4.0:2 2 Channel amp and it had a 1 30 amp on it. And at a local store they have a amp kit with 8 gauge wiring with a 100 amp Maxi fuse. Will this kit be fine for this amp or no?

my 4 gauge has a 60A fuse on it now..but when i get my 4 channel installed it will have a 100A maxi fuse..but i use 4 gauge..what if u wanna get a 4 channel..stick with 4 guage or bigger..8 gauge just isnt enough..unless you want it and on budget thats fine

it's also dependent on the length of wire

A 100 amp fuse is too high to adequately protect an 8-gauge wire, regardless of length.

What about 80A?

For a 17ft run of True 8 gauge (AWG) , 50A is your max load

Is there a quick reference guide with a chart on max wire load by gauge anywhere on the net? I'd love to have it if its out there.

Google isn't being helpful today.

thanks alot dewd! My 8 gauge wire is sure to combust any day with a 1000w amp on it and a 80a fuse >_

Is it cool to split 4ga > 6ga? Seems to me the rule of thumb is even number splits but that might just be common practice as opposed to necessary..?

I'm confused as to what you're asking. You can split to any awg wire, just make sure if you're going smaller, then fuse appropriately.
