audiofanaticz Posted September 24, 2011 Report Share Posted September 24, 2011 (edited) disconnect bass knob. redo gain setting. those knobs have been known to create problems Just AQ? Or all bass knobs? Just the AQ knobs. However some amps will put out more power with out the knobs connected.

dkahns51 Posted September 25, 2011 Report Share Posted September 25, 2011 MY rockford T2500 bd cp makes a humming noise while setting the gains high.. just because the Output meter light is on red and i believe that is what is making the sound. Nothing is wrong with the amp though.

TonyD'Amore Posted November 17, 2011 Report Share Posted November 17, 2011 Class D amplifiers put out some nasty %^&* when they are about to reach clipping, or during clipping. This is the noise you hear. Its not awesome, but it is what it is with Class D. Quote Link to comment Share on other sites More sharing options...
