1、8~24VDC is recommended; upper than 26V, it will be damaged, lower than 8V, it will generate noise.
2、Driving 4Ω load, power supply must be under 12V; and driving 8Ω load, supply must be under 24V.
3、The supply current must be 2A at least.
4、If the module works upper 20W x 2, a cooling fin may be needed.
5、The module is designed for audio signal range 0.5V~1.5V.

2) Check that if the power supply is low that cannot drive the speaker. 2A power supply current is ok.
2、 Floor noise in speaker when playing
1) Play another music to verify the noise is not related with music itself.
