How to using LM324M amplifier circuit for AUX speaker output

[Ahmed Sobhy]

hello everyone; I have a small external speaker with its own electronic board which has a 12 volt power outlet and an external speaker output as shown in the attached pictures, The board has LM324M amplifier, My question here is can I use this speaker as an external speaker for the computer using an AUX cable

 I could not find any information on the Sonico Eastern er337.  I take it that it runs off the 12 volt car battery. Also the output to the speaker is two wires so that must be mono not stereo output. You could try it and see how well it works. As the input is for a microphone it expects low level inputs.
