True, and the two positions are 1.4v and 26dB, so they aren't exactly consistent with their units. For what it's worth the 1.4v setting has a gain of 32.1dB on the CE2000 and 30.5dB on the CE1000.

[Edit] And since it's the CE4000 being discussed: 39dB and 33.8 are the gain figures for the .775v and 1.4v settings.

Actually they being consistant.  The VOLTAGE rating is the required input voltage to achieve full output.  Yes the gain of the amplifier will change with the output "wattage".

The 26dB gain position mean that that as long as all the amps in the system are set to this position, it will provide 26dB of gian over the input signal.

Which one you use depends on how you want your system to 'setup".

Right, if I remember correctly, the Crown 26dB gain position means that the amp provides 26dB more output than its input. The other setting means it takes that much voltage to drive the amp to full power.

Carvin tops plastic box single 15 and 1 (high passed at 50Hz and running full range)

Well there is one fairly obvious thing that is consuming a bunch of amp headroom, the whole point of using a sub is to take the low bass load off the mains. Unless the Cosmos has full crossover functionality(both low and high outputs) get rid of it and install a proper electronic crossover.
