Brand new here and need some help. I have 2 amps a Rockford Fosgate Prime 1200x1 and a Punch p400x4 amp. I want to run a second battery but i am not sure if this is correct. I have a 200-amp fuse at my main battery run with 0 gauge. Do I just run another 200 amp fuse at the end of the 0 gauge then through a fuse holder to the 2nd battery? Then off that 2 separate fuse holder and fuses for each amp?
