can the jbl 1200 go down to 1 ohm?

yes it can, it will only pump out 1200w rms tho, like at 2 ohms. the damping factor decreases though from 2 ohms and you'll get muddier, sloppier bass than if youd run it at 2 ohms or 4 ohms. i would reccomend staying at 2 ohms if you can.

it's a class D amp.
the damping factor shouldn't be affected, since at 1 Ohm, the sampling rates stay the same, and the output stage is throttled digitally, so the output is left the same, or more specifically, the signal is reconstructed at the same output for 1 Ohm as for 2 Ohms by the amplifier's circuitry.
That would however be true if the amp were a class AB.
Then your slew rate, damping factor, THD, etc would be more drastically affected.

no big deal. unless you understand how a class-D amp works, it's an easy mistake to make.
I think I wrote a little faq on amp classes, let me see if I have a link for it..

ah yes, here it is:
