Hello,
This is my first post, and class-d amp project.
I Bought a ta2020 dc amplifier board off ebay, which came with wired inputs and output and a volume pot. I had a home in-wall center channel speaker with 2 4" mids and a 1" al. tweeter with +/- 3db switch. I have a bluetooth receiver board, and a car usb adapter I can scavenge for 12v to 5v step down.
I would like to have it powered by a battery or external dc input (laptop 12v 4A power supply), and if possible allow charging of the battery with the external power supply.
The main question I have at this time is how to convert the stereo to mono for the speaker, and any tips in general would be greatly accepted, thanks!
