I have 2 Rockford 1500.1 BDCP'S at 1 ohm, 1 arc audio 300.4. I have the big 3, stock 120 amp alt, and new Die hard advance gold AGM 875 cca under the hood. I have some generic batt that is supposed to be equal to somewhere in between xs power D3400-D3100. The car audio shop swears by this batt and showed me another ride that it was in and says they have been putting that batt in car's and trucks with system upto 4000 watts RMS with zero problems.
The battery was working fine for 6 days and then the warning light came on saying "battery saver active" meaning that the car is not getting the proper amperage. Then a few hours later the lights starts to dim when the bass hits. I've been told some many thing by some many people I'm confused. Some have said go with an isolator, others have said go with a yellow top under the hood and 2 yellow top in the back. I've been told that the Die hard even though it's an AGM batt does not work like car audio batts. Any advice would be nice and sorry for the long post but I didn't want to miss anything. It's a 2012 Buick Regal
The ground is run directly from the front to the back and I have no idea what the name of the batt is, it's from one of those battery stores, like battery plus, battery tech type of stores
