One thing to try is running a common ground from the HU to the amp. It does not have to huge guage wires. What you are doing is making a common signal ground. Of course you want to make sure that your power grounds are good.

Make sure your amp is grounded to a solid paint free area. If you have paint on your ground point it can cause a whine. Also if you have rcas that screw to get tighter or looser make sure they are screwed in all the way if they are loose it can also cause a whine.
