What size fuse

[solidcrowd 10+ year member]

I have a jbl1201.1 and it's max current draw is 115amps and I'm planning on getting a front stage amp that puts out about 75-120 amps X 2. So what size fuse should i choose when i order the 0 gauge knukonceptz Kolossus wire? I was thinking 250amp?

I'm sure some people will recommend 250-300A since 1/0 can safely handle that much, but given your equipment - 150A will do the job and provide a lot more protection.
