Two XY-AP50L D-class audio amplifiers (or any other similar boards for that matter).
I want to make them work from a non-stabilized 24 V DC supply (bus alternator + 24 V batteries).
At the moment I'm using a 24 V-12 V DC-DC converter rated at 50 A to feed stabilized 12 V to these amps. This way I can be sure both boards won't get overvoltage, also don't need to push them to the specifitcation limits, so powering by half-voltage seems reasonable. This setup works fine so far.
Now I'm curious is it possible to power these amps by wiring them to to 24 V directly in series like on the picture.
Will they get half of the 24 V (that is, half of 24 V or slightly higher?) What kind of impact on a D-class circuitry such a scheme will make? In general, will this scheme work for two identical 12 V AB-class amplifiers?
