Sure Electronics AA-AB32165 2x25W at 6 Ohm TDA7492 Class-D Audio Amplifier Board Only
Can it run 1x 275-051 and 1x 297-436 in mono? What about stereo (2 tweeters, 2 midwoofers)?
It can run one woofer and one tweeter on a single channel but you cannot combine left and right. You can run a pair of speakers on this amp.

Will a 20.5 vdc power supply work with it?
The manufacturer only recommends a power supply range of 14 to 19 VDC.

How do I power 2 of these amps, 1 Parts Express AA-AB32131, and 1 Parts Express Bluetooth 4.0 Audio Receiver? I'm building a soundbar with 6 speakers (2 lows, 2 mids, 2 highs) and only want 1 power cord. Will also put in a on/off switch too.

The title = "2 x 25W @ 4ohm." Under "specifications" = "25W @ 6ohms". The manual "25W @ 6ohms". However, the manual M# doesn't correspond with this M# and the product I received doesn't match either. Which is it? 4ohm or 6ohm. So much mis-information!
Just spoke with PE. There is no 2 x 25W @ 4ohm spec in the manual. Only 2x25W @ 6ohm spec. However, the gentlemen did say that 4ohm speakers would work and should result in more wattage tan listed. Hopefully, they will correct their page to reflect the correct information.

According to the model # printed on mine it is: AA-AB32361V131. However, the manual states Model # AA-AB34165, and to make matters more confusing the description on this PE site says model # AA-AB32165. What gives with the three different model #'s?
Spoke with PE and they too were perplexed by the model number I received, AB32361, which is different from the listed model number AB32165. They assumed it may be the same unit but a newer model and are checking it out now and will get back with me at which time I will post their answer.

Does this, or any similar amplifier module you sell, have provisions for some sort of "power up when signal is applied" control option? Either input signal sensing or maybe some sort of "apply [5-12V] here to power up" system.
Not an answer just a further observation: In the ornery of the PCB near the inputs there are two pairs of contact points labeled STBY/GND and MUTE/GND. They're not mentioned in the manual. Could this be what I need - an undocumented feature?
