2x25W at 4 Ohm TDA7492 Class-D Audio Amplifier Board Only
What is the input impedance of this amp and drive requirements? Can it be driven from the headphone output of a communications receiver without any padding?
Would a 15V 1.4A power supply work with this amp? I'm not sure that 1.4A is enough.
Is it possible to bridge this amplifier? If yes how would I go about doing it?
This amplifier cannot be bridged.

The amp pictured has a heat-sink, yet the description indicates it doesn't need one. Is there a heat-sink installed on the board as shown?
Yes this does include a mounted heat sink as pictured. I will have the copy fixed.

Would this amp behave nicely in a car setup, simply hooked up to the battery and chassis ground, without picking up alternator noise? Also, would it make the dreaded turn on pop if setup in a delayed turn-on configuration?
This will work well in a car application, alternator noise should not be an issue if properly ground. You should have no issues with turn on pop if used with a power up delay.
