I've earned an old amplifier with speakers that a friend was throwing away and since the amplifier was not working, I decided to recycle the speakers with an wireless bluetooth set.

check your amp board schematics for the power supply info.

in my case its 8-25V DC. and i have a box full of old ones.

always check the Voltage to see if it's working well
