Chris Downs Posted July 19, 2016 Report Share Posted July 19, 2016 i just got a 2006 hyundai azera and the stereo needed to be replaced. i upgraded to a kenwood dpx792bh. its ounds great except there is a faint hissing static noise that plays all of the time. no matter what source its on, aux, usb, bt, radio, cd. even when its at 0 volume it has the noise. it doesnt increase in volume at all its just one constant hiss. i took it back to the best buy installer and he said it was unfixable, and probably a factory amp problem. i dont know much about car audio in general and wanted some second opinions. Thanks! Link to comment Share on other sites More sharing options...
mothra Posted July 20, 2016 Report Share Posted July 20, 2016 sounds like ground loop noise or that the deck is sending too much voltage to the OEM amp if there is one. if nothing changes, nothing changes You don't know what you don't know, till you don't know Link to comment Share on other sites More sharing options...

B-Sh0t Posted July 24, 2016 Report Share Posted July 24, 2016 Ground the HU at the same place the amp/factory amp is grounded. will normally cure it 90% of the time. Link to comment Share on other sites More sharing options...
