What size fuse to run?

[CMattox23 10+ year member]

I know a lot of stuff but when it comes to this I'm not too confident and just wanted to double check. I was told by somebody that a rule of thumb for choosing the fuse size is 10amps per 100watts. So I went with a 150 amp fuse thinking I was going to order a pb asa1500.1, but never did due to a good deal on a crossfire vr1000d. Long story short, am I good with this crossfire with this size of fuse? Thanks

Crossfire recommended an External 120A fuse for that amplifier.

So stick with what they recommended.

You need to run the same amount of fuse that the amp already has.

For example. My SAE has 5-30 amp fuses. So my fuse in the distro block for it is 150. And my 4 channel is a 50 amp fuse. So my main fuse is 200.
