speaker crackle?

[crusher]

Not an ICE guy but I have this slight problemI have a Kenwood CD player. My speaker crackling or vibrating (hope you guys understand) when I turn on the volume on radio . But on CD player or USB stick, it does not happen. Any ideas why? Do I need to adjust the player?

Could be static and radio broadcast are not high quality. Could be due to your radio signal not clean due to broken antena.
