I agree that overpowering subs tends to blow them less. However, that is usually because they are recieving less watts than perhaps a lower output amp driven into clipping, by a loose nut on the gain control.
But I'm an idiot, so consider the source.
I agree with the Idiot, but I guess it takes on to know one :jawdrop: It's more like overdriving the underpowered amp vs. not enough power for the speaker
