Thread: Total amp draw and 2 fuses.

here's another way to figure it out with a calculator

be sure to select the class inside the amp, in adition to entering the efficiency.

It provides a bunch of other useful info like wire size. The link at the lower right will show some more of the theory behind it.

I totally spaced out efficiency. Good explanation on the 2 fuse thing.

you guys are going about this the wrong way. the fuse at the batt is to protect the car. you fuse the wire, not the device. so if your running say a 4awg wire max fuse at the batt should be 125 amps. go up a size to 2awg and the max fuse rating is 200 amps. so the man fuse should be fusing just the wire where as the fuses on the amp actually protect the amp itself.

you're right, lets just assume a wire and fuse it.

I think the gist of the previous calcs was for a deeper understanding of the device fuses (which was a question of his in the second post), and a means for a confident determination of the wire size to the amp based on it's current draw, which would be protected as you have so eloquently and kindly stated.

If you look through pokki's posts again, he has already stated that, and it's well covered in the link I provided.

No one likes a guy coming in, reading half of the thread, missing the relevant info, and telling everyone they're "wrong". Have a nice day

we all know you meant parallel, it's ok.

hahah...damn thanks for the help guys...it definately makes a lot more sense now.
