DB Don... I was looking at the situation from the perspective of treating each woofer and it's enclosure as a resistor, capacitor, and inductor.... if we series/parallel 36 sets to 1ohm, I don't see the situation being much different from 4 drivers in parrallel to 1ohm...

of course power compression will be different, and thinking about it now the increased loading inside the vehicle would have to make a difference in the radiation impedance.. (increasing it)

but I just don't see a difference in the loads other then that ???





At anyrate.... if the psu Fets are what gave out, I would say that the amp could have been on it's last legs and probably didn't like the input voltage... I don't know how the amps were modded, but if it was only to disable the protection circuitry, well that does not necassarilly mean the amps will be rock solid on 16+ volts....

Don't discount the possibility of a short... you could have been drawing excessive amounts of current from amp, and the psu just happened to give out before the outputs.... clipping will also tax the psu...
