Keeping this simple, I have three amps (or more) that I tend to install. I have a distribution block with no fuses in it. I dont want to wreck my amps. Can I put 100 to 200amp circuit breakers on each power wire coming from the block to the amp? or should I just find a fused block? I have a 300amp fuse under the hood on a 0 gauge wire to the block. Then 4 gauge wires to the amps (would like to make them 2 guage).

The plan is two ZX750 kicker amps, and 1 ZX650 4 channel amp.

Back to the question: Can I put 100 to 200amp circuit breakers on each power wire coming from the block to the amp? or should I just find a fused block?

 

I would go with the fused distro block. I think u should be good with ur current set-up. The internal fuses on the amps will protect them.

 

this will work in ur situation. i just installed one of these and their ground block

Without researching the internal fuse ratings of each amp, you'll want a fuse or CB that's at least the fuse rating of the particular amp. With that said, a fuse will be cheaper than a CB, but the CB will be reusable... But I've only ever blown 1-2 fuses in my life... A fused distro block would be ideal, IMHO.

 

if u wanna figure out what size fuses u will need. use this site

and go to section/chapter 16. Wire

and then go tot he bottom of the page and find this
"system power design assistant"

then just plug ur information into the necessary spots

 

the less number of fuses the better...so 1 fuse and a distro block would be ideal. a fuse acts as a choke point for current...so if you can minimize the number of fuses, you will have over-all better current flow.
