A Class G amplifier with four ouput devices will
have two split rails for the power amplifier.
Something like 15-0-15 V and 40-0-40 V.
(Though the Carver blurb cloaims the amplifiers have
a tracking power supply whatever that means)
Should be easy to check by tracing the power supply.
If the above is true and the high voltage rails are
ascertained, then with an assumption of 300 to 500W
you can derive the correct range for the driver load.
Still think testing with various loads is required, just
to confirm no manipulation of output impedfance.

.Just add a few general notes :
You should be looking at something like a sealed version of
the D3 to use with the subwoofer amplifier and speaker.
http://www.speakerbuilder.net/web_files/Projects/D3/dayton3.htm
A 24/db/octave L/R passive crossover will be required
at ~ 100Hz for the above, this will not be cheap.
You need to make sure the subwoofer is more
sensitive than the midrange / tweeter combination.
A level control potentiometer will need adding to
the subwoofer amplifier to match bass and midrange.

This deals with adding positive and negative resistance.

Throwing in some capacitors into the mix you can vary
impedance with frequency, just as easily as you can
vary the frequency response with active filters.
Finding any design information is much more difficult
though, the point is to know it can be done.
