I have 2 Orion H2 12.2 subs that will be powered by an Orion 2500D amp at 1 Ohm (I think). I've been searching high and low for all my options. I am going to do the Big3 upgrade for sure but i was thinking about getting a Kinetik HC1800 battery for a secondary battery in the back and I still have my regular Duralast Battery in the front. I'm going to run 0 gauge throughout my truck (2004 Jeep Grand Cherokee). I have a stock 136 Amp alternator.Thoughts?????
