So I have a 4 AWG Power Cord that can handle up to 150A in amps.

I want to purchase an amp that is 30A x 2 which is 60A and another amp that is 80A x 1 so total is 140 Amps.

Now my fuse holder is Mini ANL and has I believe a 150 Mini ANL powering a bad amp that has lost it's sub channel.

I should be fine in installing the 2 amps being 140A totalled with that 150 Mini ANL fuse installed?

Also, would it be logical to buy a distribution block with separate fuses for the 2 amps or should the Mini ANL 150 be suffice for a Power Distro Block without individual fuses?

There is NO need for individual fuses. You got the engine one covered and the power wire at your amps will go, for added safety you can but not needed. Your fuse rating is perfectly fine as those amps will never reach even 100 amps.

so long as each amp has individual, internal fuses, there is not need for more individual fuses
