TDA7492 Digital Audio Amplifier Board 2x50W
Where in the circuits would you wire in a potentiometer? Input/Output? Also, are there any reliable places, either here or elsewhere on the web to review how the wiring of one is to be done?
How do I hook up a female auxiliary 3.5mm cord to this amp? Also, what does the plug with the three wires do?
The three wire cable is for the auxiliary input on this amplifier. The black is ground, the white is left channel and the red is right channel.

From the schematic, I can not tell how to bridge this amplifier. Any help would be appreciated. Forgive me if it was already posted above and I didn't catch it.
In order to bridge this amplifier you have to combine the inputs and parallel the outputs, basically wiring the output positives together as well as the negatives, then run this singular output into the speaker.

please explain to me how to hook up the channels, mono and two channel? also, what are the 3 wires and plug for? (red, black, white) wires
Do you have a suggestion for a power switch (on/off) that would be appropriate for this amp?
You can switch off the DC voltage with a rocker switch like the 060-302

I'm wondering what the limitation is for running into 4ohms at 24 volts. I picked up a great 24 switching supply (https://www.parts-express.com/24-vdc-5a-switching-power-supply-with-25-x-55mm-plug--120-055) from Parts Express. Would be nice to use it, but
