1. low wattage class D amps
2. instead of a DpDt switch
3. Could you wire a speaker to two amps if only one amp is turned on at one time?
4. If problem of voltage going into the 2nd amp, could you used a diode (size?) and I assumed only on one leg of the circuit.
Thanks

Maybe I didn't word this correctly: Before I try it and maybe damage an amp, I was wondering if connecting two amps (only one will be on at a time) to a speaker would damage the amp that is not on.
Thanks

Simply answer is no, you can't do this, and yes, it may damage the amp.
Unpowered circuitry can behave unpredictably when subject to non standard voltage inputs, and that applies more so to circuitry on a chip such as Class D... for example there could be 'parasitic' semiconductor junctions that come into play, each behaving unpredictably and in a non linear way, possibly even forming parasitic parts such as a thyristor that would latch and short out the applied voltage.
Any kind of diode or diodes used to isolate a speaker feed from seeing an externally applied voltage would prevent that feed working normally when required.
So the simple answer is no 🙂

Thanks for answering - what volt and amp diode would you think that low powered speakers/ amps would need?
Mooly is quite right, "Any kind of diode or diodes used to isolate a speaker feed from seeing an externally applied voltage would prevent that feed working normally when required".
No diode will do as it won't work.
No diode will do as it won't work.
If the amp has speaker protection with relay then maybe but with active GND reaching to your other amp
If the amp has no speaker protection with relay then No
If the amp has no speaker protection with relay then No

These are the same answers as was given a few days ago in another Thread.
Why are we tolerating the duplication of the question?
