i just find in a other post, the hall sensor is on the neg terminal of the batery. So its important to not connect anything on the neg pole of the battery.

Where its safe to connect my 12V+ 4 gauge wire for my amplifier? At the #1 or #2. I know we have a sensor at the 12v+ to see curent draw... but i dont know where its best to connect to not mess with that sensor... thanks.

ok thanks i will do that. a big thanks to all this good information.

ok but when the fuse will blow? never?

yes 12v dc can accept 14.4v to. ok only 4 gauge in beetween my the batterie. and 0 gauge in the back for the amp to the rear battery. i will post some other pics tomorow im making the box now.

wow your helping me a lot! ok i will run 0 gauge wire from 12v+ and 12v- from the feont to the rear. with a fuse at 100 amp in front. i will plug my amplier at the rear 12v+ and 12v- at on the body of the leaf. do i need to ground the 12v- in the back to the body of the leaf? and i will use...

just to be clear the second battery in my trunk with a 80amp fuse between the mainbattery and the second? and i plug my amp at the rear? and when a big surge will come, the 80 amp fuse will blow to protect my dcdc converter?

yea i have a yellow top primary batterie but how i connect a second batterie? and how the seconde battery will protect my dcdc converter?

what is the difference in using to batteries in the setup? if i use only one batteries with a 100 amp fuse, the dc dc converter will be protected from to much draw with the 100 amp fuse? 2 batteries with help in what way? can you explain to me the difference?

ok if i want to use a 5000w amp on my leaf... i think i cant because the dc dc converter have a max draw current at 135 amp? i dont want fry something... so if i use a 100 amp before my 5000w amplifier the fuse will blow if i suck to much current no?

very big 18 inch sub... i talk about the dc/dccconverter from the leaf to feed the 12v current... i think it can handle only 135 amp so if i use a audio amplifier of 150 amp maybe i will blow my dc/dc leaf converter?

so i need to downgrade my fuse from 150 amp to 100 amp to be safe?

can i use a 150 amp fuse on the 12v+ with a 0 gauge wire to power a big sub amp or i will fry my dc/dc converter? i read somewhere the dc/dc converter can provide 135 amp... so if i draw more than that whats happen? thanks a lot and sorry for my english im french.

how we can be sure to bot draw to much current from the 12v system and fry the dc/dc converter? can i use a 0 gauge wire with a 150amp fuse or its to much? i readed somewhere the dc/dc converter can give 135 amp so whats happe if i try to draw more thant 135amp? thanks.

if i run a 0gauge wire from the +12v wirh a 150amp fuse and i use a big amp for my sub... do you think i can kill the dc/dc inverter? maybe i need to pus a 100 amp fuse to limite my draw? thanks
