Fuses on distro too big?

[klepto 10+ year member]

So im running a distro to my 2 amps, a Massive P400.4 for the components and a Massive P1000.1 to my sub. In the massive manual it says to run a 60 amp fuse for the p1000.1 and a 40 amp fuse for the p400.4.

I have a single run of 0ga fused at the battery with a 200amp fuse running back to the distro. In the fused distro i have a 100amp fuse running to the p1000.1 and a 60 amp fuse running to the 400.4. Is there a chance i can blow my amps by having fuses to large in the distro? I see an external 40amp fuse on the p400.4 but not one on the p1000.1, which leads my to believe the 1000.1 doesent have any internal fuses.

So are my amps safe or do i need some smaller fuses in the distro?

BTW the distro block requires mini ANL type fuses which i cant find anywhere except for online. I tried orchard, Fry's and Radioshack to no avail. Any ideas where i could find some in a local store? i need these by tomorow.

I have the mini anl's.

But something to remember here.. you're not fusing to protect the amps, per se, but the wire. If you have 4awg splitting off of that distro, those fuses are fine.. albeit a little small, but still fine. 4Awg can handle a maximum current draw of 150a over approximatly 10 feet.

I'm running an 100A fuse on 4ga. wire for my 800W RMS amp. Never blown the fuse.
