A few years ago, the audio and power amplifier were plugged in and could still be used, mainly because the audio cable could be repaired. What should be after the thread is finished?
The power amplifier is connected to the speaker with a banana plug. The two wires of the power amplifier output are connected with the two wires of the speaker, the red one is connected with the red one, and the black one is connected with the black one. Two speakers are plugged in the same position. You should take a clear photo of the post behind the amplifier and let others help you.
