The reason why the other dude is suggesting a 120A fuse is so that the fuse could protect your amp in the case that it has a failure...however, the amp already has external fuses built into it, therefore it is not necessary.
So then what do you do when fusing between batteries? //content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif
Its not for the amplifier so much but for the run from the battery to the amp. If it shorts to ground, it will pop the 250 amp fuse and protect the car from burning to the ground. But if the wire get puntured by something with more resistance then straight metal it could draw enough to not pop the fuse but still become a fire hazard. I know that it is pretty unlikely, but like I said I would rather be safe.
Um, what? Did you just make this up?
Yup, just like I made up the Ohm Chart.
Electricity moves far to fast to make any difference. Maybe it will blow more quickly, but do you really think a thousandth or MAYBE a hundredth of a second is going to make a difference?
In this case, shorter is better, doesnt matter by how much... I feel safer. but thats my advice to OP
If that's the case, then what do you fuse your wire between batteries to? Serious question...
150a
So the 100+A that the wire can still safely handle is wasted? I guess you like wasting your money bro.....
