If a speaker handles 1000 watts rms @ 1 ohm then does it follow @ 2 ohms 500 and @ 4 ohms 250.
Is this the basic premis for all speakers?

Next, As a rule,does an amp run cleaner, and cooler at 4 ohms than 1 ohm.

Last, (2) dual 2 ohm speakers. Can I wire each speaker in series with itself to get 4 ohms, then parallel them down to get 2 ohms to feed off one mono amp?

Yes, the general rule, is every time the ohmload halfs, the power doubles. 2 2 ohm dvc subs can be wired in series/parallel, and yes you will get 2 ohms.
An amp will run hotter at 1 ohm, than it will at 4 ohms.

For example, a 1000 watt rms amp will put out 1000 watts at 1 ohm.
Then if wired to 2 ohms, it will only put out 500 watts rms.
Then at 4 ohms, only 250.
and at 8 ohms... don't know why you would wan't too.
