Fuses or circuit breakers and how many?

[ROCNROLL]

I'm gonna be running 2 runs 0awg with a secondary battery in the back. Amps are RF 2500bd (subs) and RF1000ab (mids and highs). What size and how many fuses will I need or should I just do circuit breakers instead?

How many amps does your alternator produce?

Don't want fuses too much higher than your alternator can produce because they won't blow if too high

My alternator produces 100 amps so I'm using 150amp fuse which might be a little too high honestly

I plan on getting a ces 270

So 300amp would be what I would use if I were running 270amp alternator

Going to need 4. One for under the hood. One before the positive terminal on your rear battery. One in between each amp and the positive terminal on the rear battery

I'm thinking about going with the circuit breakers instead of the fuses

Fuse for the wire amperage rating. Breakers are really nice. I've had them before.

Could I use breakers for the entire setup or do I need to have fuses being that serve the same purpose?

 

[Popwarhomie]

You can use just breakers. I had a 250 amp on my alternator power wire and a 300 on 1/0 running to the amp.

300 amp fuses. You are going to need 4 total for the runs from the battery to the second battery. Fuses must be within 18" of the battery so you need one fuse on each end of each run between the 2 batteries
