In order to reduce the attenuation of the signal on the lead wire, the thick special audio wire should be used as much as possible to connect; in order to avoid overloading the speaker, the volume of the power amplifier should not be too large when using it; do not plug in the sound when the power amplifier is turned on. Prevent damage to the speaker.
