Signal interference. Make sure your power wire and rca's are running down separate sides, decent rcas can help prevent interference too. Check the simple things first.

 

Make sure your chassis ground (on both ends) is in good order as well.

 

Do they rumble the whole time, if they do, you might make sure your negative wire isn't grounded.
