Need help, 2nd battery install.

[jailhouseracer8 10+ year member]

Have a question about installing a 2nd battery in my 1999 suburban. Im running 4, 12" subs, a concept cd-2410, and a stinger sp-800 battery. Im mounting the second battery(stinger) behind my 2nd row of seats. I want to tap into my charging system. Do i have to run 2 seperate runs of 1/0 for the positive, and negative side from up front. Can i chassi ground the stinger? or do i have to run a seperate wire for each side? any help will be appreciated! thanks, Ed

Why arent you running the second battery in the aux tray on the drivers side?

you could run two runs of 1/0, one for each but its easier to run one positive and then the ground to the chassis

Do you run these wires in parallel from the battery or do you hook the 2nd battery up in series with the first battery? not sure how this is supposed to be done?
