Arrow Does bridging ever provide power more than 2 times

MY question is if 2 amps are rated at 100W at 2Ohms each and if we bridge them and place 4 Ohm load at their outputs then will the power output will be 200W

It should be two times, but in some cases it turns up a little less
(e.g. 190W instead of 200W)

No.

Power output will remain at or around 100 watts.

Because the impedance doubles. Power output is halved.
Instead of each amp delivering 100 watts, each amp delivers 50 watts.

No losses

will be exactly 200 W (I think)

each amp see 2 Ohm, hence 100W+100W= 200W
