well i think that it's time for me to chime in too... you are all failing to see his (mark's) point, or at least what i think he is trying to say. fact is, the gain does change the volume. there is no arguing that. he isn't advising that everyone forget about the HU volume and run to the trunk when their favorite song comes on. if you turn your gains up, the volume goes up. yes, there might be clipping, but going from 200 to 800 watts will make things louder. especially if you amp can put out 800 clean watts.
