Fuses

[turnstylez18 10+ year member]

k what size fuses should i use for my 2 amp set up...i have a pg x600.1 that recommends 60A and has no internal fuse..and a pg 4.0:2 that recommends 25A.

What should i use under the hood and in the distribution blocks?

These are 2 suggestions ppl offered.

100A under the hood and 2 small size fuses (like 20A) in the distr. block

or

80A under the hood and a (60A fuse for the pg x600.1 and 30A for the other pg amp in the dist. block)

i need fuses in the dist. block cuz there's fuse holders..

so what would u do? i dont want to fry my amps

What gauge wire do you have running from your amp to ur distro block?

fuse your amps to what the manufacturer recommends, and the fuse under the hood can be anywhere between the current draw of your amps and the maximum current capacity of the wire itself.

an 80A under the hood should be sufficient, seeing as how you have a fused distrobution block. I am not sure what the distro should be fused at though, I would think 20A would be enough, but I am not experienced with many distro blocks.

look at the second chart down, fuse ur wire to whatever ampacity that chart shows

Edit: ok 4 guage use ~95 amp fuse then, i'm usin an 80, with the distance from battery to trunk that should be fine.

If your distro block can work without the fuse, then I wouldnt use it. Just an 80-100 under the hood should be plenty.

so what should i do? 80A? what about the dist. block?

85-100 under the hood. 60 for the xenon, 25 for the other amp.

k i dont think they make 85 in maxi fuses...25 for agu...what other ratings should i do?

 

[turnstylez18 10+ year member]

k im going with 80A under the hood, 60 and 25 in the dist. block...

what do u think? is this good?

That will be fine man, fuses normally handle more than their rating, and amps draw less than they are rated for.
