Sounds Good said:
can you elaborate?
it sonds like... umm... ok if your hooking the sub up... and say its powered on then you plug in the rca cable, and if you acedently ground it on the metel of the reciever the speaker makes that BRRRRR sound... thats what it sounnds like... but all conections are secure....
OK, so this sound comes when you feed a signal, CD in this case, and try to play it? Does it happen when no signal is fed to the system and no signal to the sub? Trying to isolate the source of this sound, sub amp, CD player fault, who knows. Could something in the sub be loose hence perhaps a mechanical sound?
Or, as was posted, a ground loop sound? That is why th eisolation to one thing that causes this sound consistently. All CD playing?
