Well I guess I do not care about numbers these are for the street. For reference same vehicle I had 2 Treo 15" SSX tuned to 35 hertz behind the rear seat in a nonwall and pulled a 153.? on just 2 of the amps in the picture. So I am trying something a little different in the new box so I will have to say I should be able to pull over a 56 but I am really just hooping to tear my head of with it.what kinda numbers are you hoping to put up with the pair?
