Big 3...bypassing The Fuse Box?


Recommended Posts

Sorry, its probably been asked before. Im sure it has. But anyway Im going to do the Big 3 and like many cars My 01 Grand Cherokee has + from battery going to alt and also another + from battery going to the fuse box. Will it hurt anything to just take that out and run straight to the alt? Also no more room on my Battery Terminal to just ADD my big 3, I need to replace my factory wire completely.

I wanted to do that...but like I said I have no room on my battery terminal to keep the stock wire and have the 0 guage Im using for the big 3. If I upgrade everything to 0 guage but leave the + from the battery to the fuse box ( which I think is 8 guage stock) Will I be alright? or will that need to be 0 guage?

as said before don't touch the factory wire. what you can do about the terminal is get an aftermarket one. look around on ebay.

Yes, you can leave the factory + from the bat to the fusebox. Cause all the power your fuse box needs to run your factory electronics is already being covered by your stock wiring.

you need a battery with side posts bro. all + factory wires could be connected to the + side post and then that would free up your + top post for your audio. that's what i did to my truck.

just put a distro block or a 1/0 "T" from that 1/0 coming off your existing terminal to the alt and you 'll be cool mang.

That would Def work, but I dont have money to buy a battery right now :(

The 1/0 T sounds like a Great idea, never thought about it. Thanks.

But I guess my main question now is about the fuse/relay box and my stock wiring. Can I take all the stock wiring out and just replace it with my own 0 guage? and then just run an 8 gauge from the battery to the fuse box? Sorry if im being difficult, lol.
