It would be very surprising if bridging that amp would work ok with those speakers, and it wouldn’t surprise me if the result would be that the amp goes into a self-protective shutdown mode, or perhaps even damage.
A bridged amplifier sees a load impedance equal to one-half of the speaker’s impedance, at any given frequency. The 11A has a nominal impedance of 4 ohms, descending to 0.6 ohms at 20 kHz, so in bridged mode the amp would see that as nominally 2 ohms, descending to 0.3 ohms at 20 kHz.
Few amps would do well working into such an impedance, and that is particularly likely to be true in the case of a home theater receiver.
