Hey i am putting in a 2nd battery in my trunk and wanted to make sure i had it right. I have 2 amps the Rockford Fosgate Prime 1200x1 and the Punch p400X4. I have a 200-amp fuse under hood to a block that has a 120 for the 1200 and 60 fuse for the 400. Do i just add another 200 amp fuse before the second battery and run 2 4-gauge power wires off that 1 with 120 fuse and then another with a 60 to those amps? So ill have a 200 amp by my main battery and another 200 amp 12-18 inches before my second battery is that correct?
