When I had that problem when I had my acura legend, when I wired that, I wrapped the RCA's in Foil. The problem decreased, but didn't completely go away. it made a big difference though. Try it

Make sure your RCA's and Power cable are as far apart from each other whenever possible. Thats the big thing

Change the ground. I had the same thing with mine. I changed it to a bolt on my booster seat and the whine was gone

if your rcas are any where by each other make sure they cross at a 90 degree angle and it should eliminate your rcas from picking up that power signals, or your rcas are bad and your amp is bad. Goto best buy and pick up a ground loop isolator should solve your problem if the other two didnt
