MSI v3.0 Input Impedance?

I am having some issues with a very noisy 12 volt line to MS so I am going to put an RC filter on it. But without knowing the input impedance for MS I can't calculate the component values needed. So does anyone know?
Thanks!

The impedance isn't constant. You're better off using an LC filter as an R can cause an unacceptable voltage drop.

I use a stereo filter to clean up the DC..

SCOSCHE Single-Stage Noise Filter ES004.

There are various sizes available.
