Ishom,
The NX4-6000 is an updated version of the NU4-6000.
I have powered a pair of Keystones with a single NU4-6000, channel pairs bridged mono to each 4 ohm sub.
That said, with a three way system, normally I used one channel pair of the NU4-6000 bridged into the sub, and the other two channels for mid/high, the two amplifiers on either side of the stage to reduce cable length.
If one amplifier failed, the system could still be run mono, with one sub per channel, ~3dB less power than in bridged mono mode.

Would someone mind double checking my math? I'm considering a CVR DSP-654 to run one Keystone (two bridged channels) and one Syntripp.
The DSP-654 can put out 3740W @ 4Ω bridged and 72.1V RMS. The 18SW115-4 in the Keystone takes 3400W max and 1700W RMS, and I see Art recommends limiting RMS to 1/2 of the nominal RMS rating, so 850W.
850W at the speaker's DCR of 5.3Ω gives me 67V which is within the amp's RMS output of 72.1V. Is this sufficient, or should I oversize to something like the DSP-1004 with 2 x 5780W or the DSP-1504 with 2 x 7140W? I'm playing low-crest-factor EDM.
