Can you fix a bad RCA input on a brain unit?

[Pistonsfan70 10+ year member]

My FRONT audio input on my HU brain is faulty. I've tested the RCA's, my amp, so it has to be this. Everyime you plug the RCAS in you hear static at any volume (the static volume does not get louder, stays the same)

Any ideas on how to fix this, or can I fix this?? Let me know either way

Dodgy earth on the RCA track? Ground the outside of the rcas to a grounding point

Not sure I understand. THe actual RCA cable isn't bad, its the brain unit part thats the RCA's go into. Thanks for responding but I'm not sure what you meant lol
