from my experience no it will not be enough, and or. it would not be enough for me rather. ill tell you a little bit about why i say so. i had a 200 amp H/o and 2 yellow tops in the rear and 1 under the hood. all 0 gauge with big three, with a saz 3000D on 2 15 inch BLs,@1 ohm,. i suffered low voltage, my amp would run hot, i would blow breakers and i cooked a few alternators, i added, 1 more cell to the rear and it helped. but was still not where i wanted to be.... i ended up with 4 optimas in the rear, and 1 under the hood along with a 200 amp h/o to be able to run cool and stay with decent voltage. @1 ohm. i never ran below. lastly,. i can not for the life of me figure out how you plan to run run dual 2s at 1 ohm daily and comps ay .5 unless your going to run 1 sub daily.
