Just noticed where on low volumes, my speakers make a weird buzzing noise every 5-10 seconds, with the volume turned up you can't hear the buzzing sound but it still happens and this happens on every source, anyone know what could the problem is?

how is the headunit connected to your cars wiring. RCAs to an amp? no amp, straight to door speakers?

sounds like a bad headunit to me, i would verify first by checking the power and ground, and then try grounding the headunit directly to sheet metal. see if it changes.

if you can plug in another headunit, or even the stock headunit and the problem is gone its probably the headunit. is the headunit under warranty still?

Check grounds/amps and head unit.try a ground wire long enough at different locations as well/testing.one Kenwood I had I had to install a new firmware on it by Kenwood Techs recommendation, and all was well( I was out of warranty by time installing it)
