Fusing multiple runs of 2/0

[Cashdollar2009 10+ year member]

Quick question, I am putting two runs of 2/0 from my front battery to my rear battery bank. I understand the placement of the fusing along each line, but was curious as to the size. I am planning to run a Crescendo 3k @ 1-ohm for 3000rms. The fuseholders shipped with 150 amp anl fuses. Would it be proper to just run 150 amp fuses in each holder on each line? I understand if I were trying to squeeze 3k out of one run of wire it would be drawing too much current theoretically, but could I divide the load out between the runs? Thanks ahead!

just have a 150 through out the whole thing....... unless you have a HO alt and batterys in the back, then you would fuse it to the alt size
