currently i have the stock batt up front and a 34/75 red top in the trunk at full tilt with my current set up iirc i dont think i drop below 11.5 not that bad, and i was able to get another 34/75 red top so my question is what would benifit me the most with what i have, putting the second red up front, or putting it in the back with the other one and adding another run of 1/0 to it. keep in mind that in the next couple weeks i will be getting my second sub from being reconed so i would be running my amp at .5ohms, as opposed to being run at 1 ohm now.
