Connect Bluetooth to Crossover

Good Day,
I’m looking at building a set of 3-way speakers, which would require a crossover network. I know how to design a crossover filter and connect it to the speakers. But I would also like to make it Bluetooth.
I have found several articles explaining how to connect Bluetooth to an internal amplifier, but nothing on how to connect it to Bluetooth. Is this something that can be done, and if so, can it be done without the amplifier? Does anyone have any drawings or diagrams that you can share?
Thanks in advance.
