Inline fuse question

[TSC17 10+ year member]

I have a DLS A7 amp that draws a maximum of 120 amps. I am powering it with a 4ga power wire, but the inline fuse next to the battery is only 100 amps. I'm not driving it a full load, but could there be any potential issues there?

I've also looked around at fuses/fuse holders, and all I can find is a jump from 100amps to 150 amps. Any concerns about having a fuse either smaller than or larger than the maximum amperage draw of the amplifier?

Thanks.

The inline fuse is to protect the WIRE, not the amp.
