Fuse Size / Distro Block

[leon 10+ year member]

I am thisclose to ordering these:

KnuKonceptz 1/0

Kolossus 4 Gauge

StreetWires DBX30

But I need help. I am planning on running one line of 1/0 to the distroblock, then 1/0 to my Alpine M1005 and 4ga to my Sundown 100.2.

What fuse should I put near the battery on the 1/0? The sizes on the KnuKonceptz 1/0 are 60/80/100/150/200/250A.

Also should I put fuses after the distroblock that matches my amp? For example, the M1005 is 4x20 and the Sundown is 3x20 so that would be a 80A fuse on the 1/0 and 60A fuse in the 4/0?

I'm assuming you mean 4 gauge to your 100.2? 4/0 is 3 sizes UP from 1/0, 4 gauge is 3 sizes down from it. 1/0 = 0 gauge. 4/0 = 0000 gauge.

You don't need inline fuses for the amps if they already have fuses built in, you just need to fuse the main power wire coming off your battery, for anywhere between the total max current draw and the max capacity of the wire. 1/0 can take up to around 300A, but you're only running maybe 150 max realistically, so fuse either 150 or 200, or you COULD fuse 250 or 300, but you gain a little added protection by fusing lower
