what size fuse do I need?

[Jeff 10+ year member]

I have two JBL amps and a Coustic crossover. One amp has(2)30A fuses and the other has (2)20 amp fuses. The crossover is not fused. According to the owner's maunuals, the maximum current draws are 57A, 43A, and .5A for a total of 100.5 amps. These amps do a total of 760 watts rms. What size fuse do I need on the main power lead?

I used two power leads for my two amps and put a 60 amp fuse on one and a 40 on the other. (Sub amp and speaker amp)

100 amp fuse should be the larget fuse you use. I would use 80 - 90 amp fuse.
