It's an amp I would avoid. But it'll work. It won't put out the 2400watts cleanly that it is rated at.
And no. You can't run it at 1 ohm. Because its most likely 2 boards inside that case. Each board at 1 ohm for a final load of 2 ohms.
So if you run it at 1 ohm. You are running each board inside the case at 0.5 ohms. But you can try. The amp should just go into protect if there is a problem with heating or the ohm load being too low.
