no idea, i am playing with some #'s on bassbox pro 6 here at work, and still need to run rca's/ground/batts/remote pretty much everything aside from the dual 0g i already have in it... then i'll decide. probably start with one sub and one soundstream 2000d @ .5, then strap up two of them to it @ 1 ohm each (dual 1 sub seriesed up to 2 for the strap). Then do two subs with two the two SoundStream 2000d's @ .5ea, then maybe try the two Orion 2500d's I have @ .5 in comparison, see which set of amps is stronger. Then build a whole new big old box for three 12's? meh probably //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
