Why does the description day 380w @4ohms and the picture says 280 @ 4 ohms?

Because there are 2 different amplifiers. I believe the one pictured is the 3000 so the specifications that are listed are weird

Will it push my 1 15 Rockville sub with 1000 rms watt 2000 peak power at 2 ohm?

I'm pushing 2 12's 900 watt RMS each with no problem. Best amp you can buy for the power and price! You won't be disappointed!

Will it push my 2 12 nvx 600 rms each at 2 ohms?

I don't think you would have any problems with that. I'm pushing three kicker comp q twelve that are 800 rms at 1 ohm or lower and it doesn't struggle at all with it.

Has anyone done a dyno on this product and if so, what were the real numbers

Almost nothing. 600 watts max. Run away. Do not buy anything from this company.
