Nice vans, but SPL wise I'd use a smaller car with smaller drivers and the same power.

some nice info for you folks

you can see some things here, like

1- expected X actual gains (formula is gain = 10 log P1/Po)
2- impedance dropping as you put more power
3- Power = voltage x current, Impedance = Voltage / Current, hehe

other funny thing: it does not matter what you have inside the box, will play the frequency dictated by the port

not yet, with two SD8000s I busted 2 cones that we are testing. 11500W each amp voltage dropping to 15V.
