okay so I have an Ia 40.1 with dual inputs and grounds, now I wanted to know if this will work 100%, there 2 battries in the car 1 upfront and one in the rear if I run 2 postive runs from front to back bat and then into the amp for power, then the ground run a distro block on the negtive on the back bat with 2 0 gauge going into the grounds and then a 2/0 welding cable as the ground?
