Help w/ adding 2 batts in the back (wiring question)

[JoeRa22 10+ year member]

I've got a Yellow top under the hood and i want to add two Stinger SPV70's to the back near the amp.

I don't really want to run another 1/0 line front to back if i don't have to (- to -)

Would this be right, or am i doing something wrong?

I will be doing the big three with either 1/0 or 2ga if i don't have enough 1/0 left after the install.

Thanks i advance.

That's fine - You can use a common ground for your spv's

* Note - I would have another run of 0ga coming from the front though *

I have overkill on my runs from front to back

(2) Runs of 0ga from Battery positive in front - 1 run goin' to each battery in the back

(2) Runs of 0ga from Alt. to the back - 1 run goin' to each battery in the back

BIG 3 done - Total of (3) runs of 0ga from Alt.

* I like havin' that direct chargering link from my Alt. to all 3 Bats. - My voltage stays up about .8 - 1.4 (12.8 @ Full Tilt ) from when I just had the big 3 and only 1 run ( 11.6 @ Full Tilt )

... And this is with a stock alt.

More runs HELP!

So if im only gonna do one run, which is probaly what im gonna do unless i get unacceptable voltage drops, would it be better to run from the alt straight to a back bat.

Opposed to being from the pos in the front to a pos of one in the back?

I'd see no issue continuing to run the power wire off your front bat. To simplify things in the trunk I'd ground the amp to one of the bats and give both bats a common ground. This tends to help prevent ground loop issues as well.

If under full tilt you get big voltage drops, then I'd look at running a dedicated 0g line for the ground, as it will probably have less resistance and able to carry more current than your frame.

Thanks for the help.

I hope i can get everything up and running in the next two weeks.
