Easy, it's at half the impedance. The 2x50W is at 4 ohm, the 1x100W is at 2 ohm. If all speakers are 8 ohm, each channel will give 25W.

All the above is with a 24V supply. If you have 12V supply, divide all power output numbers by 4.

2ohms is very low impedence, might work for car subs though

I wouldn't recommend to run a 2 ohm woofer on it though. The specification shows what the chip is capable of. Not what will be useful or sound good.
