hmmm. If the amp is making noise with just the RCA plugged in then it sounds like an issue with the amp. Especially if you are plugging the MP3 player directly into the amp bypassing the RCA's in the car.
the last thing i can think of is trying to get a set of twisted pair RCA's and seeing if...
do you get whine if you take the HU out altogether? try running an mp3 player using the 3.5 mm to rca at the front and see if you get noise and if so then try at the amp directly
also there are 2 different types of RCA's so if you are using the wrong one that could cause noise. figuring that out is hella impossible though so. other things i would try are
1 pico fuse mod if the HU is a pioneer
2 Amp ground. check connection's are tight and no fraying or touching wires...
