From battery to battery, 1/0 with 300a fuse is a must.

From battery to amp, depends on the amp. You can figure that out by what size wire the amp accepts. If it accepts 4 gauge wire, the use 4 gauge and a 125a fuse. If it is 8 gauge then 8 gauge wire and 50a fuse.

Always choose your fuses by the rating of your wire. If your wire is rated at 300a, use a 300a fuse. NEVER use a fuse larger than the rating of the wire.

knu rates their 1/0 at 250a so with rating on wire i will need two 250a fuses.

my dd m3 has 1/0 inputs as well so once again another 250a fuse right?

also i have heard rate fuses on the amp when coming off the battery. anyone know the fuse rating on a dd m3? or stick with 250a?

Cool, so it is 250a for your wire. Stick with a 250a fuse all around and all is good.
