Hey there mate!

Thanks for bringing up your issue,  The issue is with your head unit poor grounding inside the unit itself.  I have had this issue previously with Sony and Pioneer head units.

What you need to do is":

• take out your current head unit;
  
• apply speaker wires around your rear RCA inputs of your head unit, into a figure '8' to all of the RCA Inputs, ( if you have three, do all of them)
  
• after you have go the bare copper speaker wires to form a figure 8 shape, apply solder so it holds it shape;
  
• Ground all the speaker wires to the rear of your head unit to one point;
  
• Reconnect all the RCA with the figure 8 wires and the RCA CABLES will hold them in place;
  
• Check your grounding point and distribution connector terminals are all securely tightened on the amplifier and the grounding point as well;
  
• Check your head unit grounding point is getting a good contact as well;
  
• Hopefully, this should rectify your issue mate!
  

Let us know how you go.
