I am certain there is an audiophile greater than I, who can explain better what I am trying to convey.

No, you did a pretty good job of explaining it.

The only thing I could add is:

Assuming those specs were true RMS specs rather than meaningless "peak" specs, then either a five-channel (for a mono sub) or a six-channel (for stereo subs or bridged-to-mono sub) amp in that range should be fine for you. Just make sure your subs and the enclosure are properly matched for that amplifier's wattage. Your installer will be able to help you make sure of this.

There are a lot of advantages to running a single amplifier if you can get away with it:

- Fewer wires.
- Easier to install.
- Takes less space.
- Fewer components means less of a chance for a noisy ground loop to develop.

The only real advantage to having a separate amp for the subwoofer is that you could probably come up with more wattage for your subs in a separate amp. But you'd be paying more that way, and if you can get a 5/6 ch. amp with enough power, then I wouldn't bother.
