tsunami power and grnd distro block with meter

Got the block, why are there two power inputs? I'm confused

Dont sweat it, they're BUSS'd. You only need a single B+ in to make all 4 fuse slots hot.

Thanks, I did notice that, but maybe it's a preference for top or bottom positioning. Not sure why you would use both B+ at the same time.

Quick question on the block. I'm running a exile harpoon, 800.4 and 600.1. What size fuse is needed for each amp in the block?

The sum of the fuses on the ends of each amp are an indication of the approximate max current draw that the amp will ever pull. No need to ever exceed this with your fuse. Most amps will average between 50% and 75% of there max. Depending on the amp's efficiency and the load placed on each chnl, you could calculate a little closer. But, its still a estimate based on the type of music played and the volume level. I would shoot for 75% of the amp's max potential draw, but not exceeding the capacity of the cable between the block and amp.

The fuse for the trunk line feeding the block needs to be able to carry the load of all the amps, yet not exceed the capacity of the cable. We always want the fuse to be the week link.

Ok so what's the max for 4 gauge?

David, the exile site has the specs and recommended wire gauge and fuses.

I believe mine are 125 each at the block.

The max current capacity for 4 ga would depend on the total length of the B+ and GND running to it. Another way to look at it. There is no advantage to having a fuse thats rated higher then the amp's max potential load (the sum of its internal fusing). So if your cable is of sufficient gauge to carry that amps potential load, then your fuse size should be within a safe range. The key is, if a short were to occur, we want the fuse or breaker to trip before the cable melts.

no simple answer for David ?

I ordered the distribution block and wireing from Brian, he sent 5 fuses for it, 2 were larger, 3 were smaller (Think 125)
I've installed the smaller ones for all 3 amps
