Answer
Not sure how you have the speakers wired, but my first guess is you do not have the impedance matched properly to the amps.  With the speakers in parallel (seems that is what you have) that is placing a 2 ohm load on the amp.

The specs on this amp say that in bridge mode the minimum load should be 4 ohms.

Why to you have the amp in bridge?  You would be better off, power wise and fidelity wise, to put the amp in stereo and have each channel feed one speaker.  That's what may be best and the loading is correct.

Try that and let me know if there is more to the story.
