80a vs 100a fuse

[littledane 10+ year member]

I cant find any local places that sell 100a fuses so i was wondering how much of a difference an 80a fuse would be. I'm running 4awg wire on stock electrical to an RE Audio dts1500.1 amp. I do plan on ordering a new 100a fuse but i dont know how much longer i can go without my system.

You will probably be fine. Worst that will happen is you will blow your fuse and be stuck looking for 100 Amp ones again. I've blown 60A fuses with around 1200 watts but was fine with 80s...
