Something in your dash is radiating noise. You'll need to find that device and either a: relocate it, or b: shield it. Those are your choices...

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

First thing I'd try is different RCA cables with better shielding and direct grounding the case of the HU to the vehicle chassis. Shielding RF away from your HU from an outside source can be difficult. First try simply improving the HU and line-level signal shielding.
