    yes, take the output from the headphone socket to an external amplifier

    unless they are tiny low powered (1-3Watts) speakers, yes

    have a look on ebay or amazon for "low powered amplifier modules

    yup :)

    Although it doesn't say, I'm assuming the BT module is stereo ?
    so you will need 2 of those amp modules for a stereo amplifier :)

    just take signal lines from the headphone socket to the 2 inputs of the
    amplifier modules..... 3 wires, left channel, right channel and ground

    and you need, as suggested in your link a 24V power supply and with 2 modules, you will need 4 Amps rather than 2A

    so again search for 24V 4A power supplies :)
