Big 3 in Dodge Charger?

[b0r 10+ year member]

With the battery in the trunk, I was wondering what the best way to go about this is. I didn't know these cars were like this, so I opened the hood and was like "wtf is my battery?" and it was in the trunk. I thought this was awesome for system purposes, but not so good for wiring upgrades.

In the engine bay, there is this big fuse box looking thing with a + - post for jumping cars/etc.

I think some of my wire is already 1/0 from the factory, but I'll have to look into that. Am I going to have to run a wire to the front of the car for +alt to +bat? It's ****** 0 gauge wire..insulate and go under car?

Stock alt's for my car are 160 amps it looks like? That's pretty nasty for stock imo. Going under the car with this wire is already giving me a headache..

Is adding a second battery a good idea with it being so close since stock is already in trunk? or am I just going to choke the alt out? Thanks if anyone has a car with batt in trunk that can help out.

Apparently I struck gold with this situation:

"On the charger you really only need to do 2 of the 3. The wire from the alt to the batt is already 1 gauge. no need to change anything with it."

I'll have to double check it but that would be nasty and save me money on wire and the headache of going under.

people run 1/0 all the time... just do it. go under the carpet. I have 5 runs of 1/0 going under my carpet. the trick is to stay under the carpet and along the edges.

If your car already has 1/0, then add another cuz it might need that extra current transfer. Wiring is positive to positve. Negative to negative and a short ground location that has to be metal eposed frame. Your alt is 160, ok. for every 1,ooowatts, you need to have 70 amps of current. If your running more then you might need to think twice. but the reserve of haveing two batts might save you..
