How big fuse do I need for power wire?

[mudder53]

I was planning on ordering this:

Copper Clad Aluminum

I will be running a Hifonics Hfi2000d which will power two Kicker Cvrs.

Can someone explain to me how big of a fuse I need on my power wire?

Oh yea.. Happy Thanksgiving!

Fuse based on wire... So you would fuse for 250amps for that wire..

You beat me to it.

250 should be perfect for your amp

good rule of thumb is to divide your rms by 10 so basically for every 100watts u need 10amps, 1600rms atleast 160amp would use a 200amp anl fuse just in case

Nooooo. Like said above you do not fuse your wire based on ur amps fusing. You fuse the wire based on the max amount of amps said wire is rated too. So If anybody buys knu cca 0awg they should buy a 250amp fuse. Only exception would be if your amp requires an external fuse because it does not have onboard fuses.
