Dude, it's from your alternator. Redo the grounds to your amp. If that doesn't fix the problem, it may be the alternator itself. I had unstoppable alternator noise, until I realized it was going bad. When I replaced it the whine went away.

Check your grounds, scrape away all of the paint under it (if there is any) also, i could be from having your rca's run along side of your power wire. If this is the case then re-route your rca's down the other side of the car.

I had this problem in my Dakota. It's a ground loop. You should check your grounds.
