Only if the amplifier can supply enough power - as I said before a bridged amplifier can only provide exactly the same power as the two individual ones, only the load impedance changes.
I'll give you a common example:
You have two 100W 4 ohm amplifiers, and two 4 ohm speakers.
You connect one speaker to each amplifier, and get 100W in each speaker, total 200W.
You now bridge the same two amplifiers, and connect the same two speakers in series across the output (giving 8 ohms), you get the exact same 100W in each speaker, and the exact same total 200W.
Where bridging gives an advantage is if you don't have the correct impedance speakers - say you only have one speaker, 8 ohm 200W. You connect the speaker to one of the amplifiers, but you now only get 50W from it - by using the two amplifiers bridged, you get the full 200W as before.
If you connect a 4 ohm speaker to the bridged amp, it will try and provide 400W to the speaker (200W from each amp) and both amplifiers will be destroyed.
