Some serious current ability, peak output current is specified as 180amps!!!, to drive down to 2ohms without a sweat, as the distortion figures don’t change from 8 to 4 to 2ohms.

The JC 1+ is specified as being able to deliver
450W into 8 ohms (26.5dBW),
850W into 4 ohms (26.3dBW),
1300W into 2 ohms (25.1dBW), all at 0.15% distortion.
