ok im running 0/1 gauge wire into a fused distribution block and running 2x 4 gauge wires out to a kicker kx350.4 and a kx600.1

i was wondering how big the fuses would have to be inside the distribution block
the fuse type is ANL....

whats the amp draw on it?

I run an 80 amp macro fuse.

ok....well... i dont no if this answers your question but....
on the kx350.4 there are 2 20 amp fuses
and on the kx600.1 there are 2 30 amp fuses...

and the fuse that i got with the 0/1 gauge is 250A which is the closest fuse to the battery....
so im not sure how big of fuses ill need in the distribution block???

IMO, I think 30 AMP in the block would be fine.

Just my opinion tho.

im assuming each 4 gauge has its own seperate fuse.....and molson one amp has 2 30 amp fuses built in....just one 30 amp wouldnt cover it, im sure hed be blow that kinda quick, 60 amps would be fine.......although you say you already have the fuse next to the battery, you dont really need any others you know.......you could just find a block that doesnt require fuses, its just less hassle and something less that can go wrong.......

ahh. missed the part about the 2 30 amp fuses. I think he already has the block, yeah, so toss some 60 ampers in there. Redundancy is good when talking about wiring. :)

yes but just because it has 2 30 amp fuses doesn't mean it will ever draw that much and if it does u wanna stop it before it even gets to those fuses. Personally I would probly just put a 50 amp fuse on the one with the 2 30 amp fuses.

I'm running 80 or 60 amp fuses in my distro block, I have a 200 amp fuse before the block.

ya go with the 60 or 80 amp

i need 2 different fuses....
so im thinking that i would put 100A on the one going into the kx350.4
and a 150A going into the kx600.1
does that sound reasonable???

That will work, overkill is better then not having enough.

thanks for all your help....
now all i need is my box (which should be done tomorrow) and i should be thumpin....

i dunno about you guys but after blowing a couple fuses I just decided to get a circuit breaker.......

After switching amps out every other year I opted for the same setup.

I like circuit breakers except for the fact that they can corrode on the inside and cause the breaker not to open incase of a short. I've seen the 1's that claim they have protected circuits from the elements and so forth still freeze up and not open. If you live anywhere where they salt the streets in the winter I would stick with the fuses because of the corrosion.
