Fuse Size

[jshak07 10+ year member]

I am going to be running a saz3000d and a 2 channel amp for my components (dont know what yet) but it will probably be 200-300 watts per channel.. As far as putting my fuses in, if i put a 300 amp ANL under the hood, what size fuses should i put in front of each amp? I will have a powermaster d5100 under the hood and a d3100 in the back with a 200 amp relay

The 3000 recommends 300 on its own, and you shouldn't run much more than that on 1/0 wire.

You might go 300 and 30 at the d-block. Your 2 ch can't be too big.

What about a run of 1/0 and a run of 4 ga or 2 runs of 1/0?

A 1/0 and a 4 would be more than sufficient.

300 on the 1/0 and up to 125 on the 4.

I dunno. I'd honestly would rather run a 0/1 AWG and then a 4 or 8 AWG seperate for my comps. That 3000 doesn't play. But I think the variables in this question are which wire, from which company, and the strand count, what resistance are you running the 3K at, and how long is the run back going to be?

The wire from front batt to rear batt is roughly 15 ft. Its 1/0 wire bougt from loudcartunez on here so I will check with him and see if he can get me the thread count.. So I will want two 300 amp fuses for the 1/0 on each end of the wire within 18" of the batts, a 300 amp fuse inbetween rear batt and amp, and than maybe a 150 or 200 on each end of the 4 ga for the comps?
