would it be ok if i used a 40amp fuse for my amp?

amp= 75x2 @ 4ohms... so i figure, amp = 150 / 12.6 = 11.90...

i have a streetwires mini-wafer fuse block... i want to use this block cuz i dont want to go buy another one.

the block has the power input end with a 2ga input, and 4 8ga outputs.

i got two of those amps (75w x 2 @ 4ohms). is it ok if i seperate them on the block with 40 amp fuses each? or should i throw them both on one fuse?

The fuses on your power wires are to protect the wires, not the amps. The amps should have their own fuses (only a very few do not.) Use the proper size fuse for the wire you are running to the amp.

yeah i phrased that question wrong. just trying to salvage the fuse block. i have a 4ga input and 8ga outputs. the lowest amperage i found available in mini-wafer designs are 40 amps. would it be ok to use those fuses or should i just buy a new, unfused dist block?

An 8 gauge wire can use up to and including a 100 amp fuse...so yes, it's fine to use a 40 ga. fuse on each of the 8 ga. wires leading out of the fused distro block.

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.
