fusing at the battery in the trunk?

[jaredspl 10+ year member]

my question is when strapping my 2 IA 20.1 do I have to fuse the power wire at the battery in the trunk also or would the fuse at the battery in the engine compartment be sufficient enough.

You want one in the engine compartment within 18" of the battery, one on the incoming input to the rear battery within 18", and one for the amps.

i went with 300a between the batteries (thats 2x 300a) and 150a going towards the amps.

xwhatever. Fuse at each battery and @ rear battery for amps.

so if i have this correct fuse in the engine compartment and run power wire to battery in trunk but fuse before connecting it at least 18 inches before, then from the batteries fuse it before the amps. so im going to have to have a total of 4 fuses. or could I use a fused distribution block and fuse only in 3 places

4 fuses, yes. depending on what you are running. you have the right idea now. yes you could use a fused distro too, but that still has 2 fuses

OK thanks. you made this a whole lot easier than I was picturing.

More money spent than is needed, plus an unfused wire. I would get rid of the distro's and run the amps straight off the battery.

i know the distro are overkill, but i had them so i used them. what wire is unfused?

Not saying you HAVE to, but its an unfused wire that has the possibility to short if it fell out of the distro.

I would fuse that wire going to the distro too, like he said if it freakishly comes out of the distro there is nothing stopping it from grounding and you then have some huge problems, if your distro is fused i would take the other 2 inlines out and put one on the other side of the distro
