the mp3 module has an output for external amplifier:
**broken link removed**
And i am using that output the DACL pin with 10uf capacitor, and the ground, as for the amplifier it rely has 4 wires as shown on the picture. This is model m032 that has 4 wires, the model m032N has 5 wires.
The speaker will be an siren speaker with 8 or 16 ohm. so i don't need stereo only mono.
So what i don't know how to do is connect this mp3 module with the volume control chip, so a schematics would be helpful , and is there any way to use this amplifier or i most search for another one ?
