Adding Another pair of Exile Towers / Calculating Amp draw

[hawaiianstyln]

Trying to make sure my ANL Fuse rating is correct.  I currently have an inline 300 Amp fuse on a 0 awg wire that goes to Dual Perko.  I've added another amp and pair of towers (total 3 pair of XM9s) and wanted to see if anyone can validate my fuse rating is still okay.  Each amp goes into a distribution block with 4 awg wiring.

1.  XM30.2 wired at 2 ohm: 420w x 2= 70 AMPS

2.  XM30.2 wired at 4 ohm: 300w x 2= 50 AMPS

3.  XM15.1 wired at 1 ohm: 1500w x 1= 125 AMPS

4.  XM15.4 wired at 2 ohm: 225w x 4= 75 AMPS

320 AMPS total from my calculations and I already have a 300 AMP inline fuse.  Is this fuse close enough?  This is all based off max power, correct?

You are fusing the 0 awg wire so that it doesn't turn into a hot knife, not the amps.  

but nevertheless, I very much doubt you can blow a 300w fuse on that draw.  I think you'll be fine.
