A higher pre-out voltage (or better HU in this case) would allow for a lower gain (or sensitivity) level to be set on the amp, and still achieve the volts (that you calculated at 40v for your crunch amp). At that 1190 watts you stated (gain @ max), it would clipping, since the amp is only rated to do 450w.When you match the gain to the rated output watts of the amp at that certain ohm level, you prevent the amp from clipping. That is the whole point of using this formula.hope it's clear to you.</blockquote>
