This might be a strange question and currently outside of my skill set.
I have two items, one being a low voltage 5v class D amp,
5wx2 stereo dual channel digital amplifier board pam8406 audio amplifier module 5v class d amplifier Sale - Banggood.com
and this cheapo music player.
Bluetooth 5.0 mp3 audio decoder music player usb tf fm radio dh digital decoding module diy sound home speaker amplifier Sale - Banggood.com
I'm currently looking at how to integrate the two of these objects into a 3d printed build, but noticed that the amp's pot turns the unit on, which made me think, can i use this as a SPST switch or similar somehow?
This is going to be used for a 7 year olds boom box and be plugged into a 5v power supply via the wall, so want as least amount of switches etc to turn this on.
Can it be done and if yes, how does one do it?
If no, no big deal, ill just look at another amp i may have sitting around.

All things are possible but this is really something you need in front of you to figure out.
For example does the amp pot switch actually switch the 5 volt rail on and off or does it instead operate as some kind of logic level standby configuration putting the chip into an 'electronically off' or 'standby' state.
If it switches a rail then you can in theory just connect a wire to that switched rail to get your second 5 volt switched line but that depends on current consumption of the player. These switches may not be super rugged and have a high current capacity.
You also need to think about how the player will respond to having its supply switched on and off in this way. Will it boot up OK and work normally or will it be a half hour job as it initialises each time the supply is removed.

You can always use a relay for switching the BT player.
As the BT player accepts large HDD's I presume it will need some current which the pot probably can't handle.
The amp has also a mute function, say if when BT player turned on it switches HDD power, use it to unmute the amp.
You have to find out they works in order to integrate them.
