\rHi David:
The SSVC6D should be a good match for the Crown amp and six pair of bookshelf speakers. The internal Volume Controls are rated like our SVC300, 300 watts peak and 150 watts RMS. The SSVC6D comes with the impedance setting at 8X for all six internal Volume Controls. The Crown appears to be a high current power amp where you could get away with setting the Impedance matching settings to 4X for all 12 jumpers especially if you play less than all six pairs at once for extended periods. Making sure you physically turn off the zone at the speaker selector.
Good choice
