Im having a problem with my audio system where there is a whine coming through the speakers that follows the engine RPM. I recently put in new door and pillar speakers and an amp for those speakers. How could I fix this problem?

From the internet:
Check the ground on your amp. You've probably just got a shitty connection. I would start with the amp. And don't double ground two components to the same point.
I'd also suggest checking your grounds. If there is nothing wrong there, they do sell noise suppressors for alternator whine.

Check and clean your grounds. when you ran the speaker and rca wires for the amp did you run them close to any power source like your amp power or other power wire? they can pick up alt noise.. rule of thumb is run speaker and rca opposite of power for amp... Stay away from the noise suppressors the actually block music freq as well and effect music volume... Also have your alt tested as it may be starting to fail and the noise suppressing circuits in it may be on their way out. Also i have found that the cheaper amps are prone to picking up this noise as well were a higher quality or amp from a good stereo shop will not have the same symptoms.
If you didn't change your alternator, its not that.
How big of an amp did you put in? Have you done the big 3? What other electrical improvements have you done?
As others have said, you're getting electrical interference through your audio wires.
Re check all your grounds are tight. You may need to remove and make sure there is a clean connection, ( metal to metal - no paint, or other grounds). Where did you make your grounds to?
If you ran your RCA wires that go to the amp, too close to the power wire that will cause alternator whine.
If your RCA wires are touching metal, or pinched, especially where they are plugged in that will cause it. Depending on which head unit you installed the RCA plugs may be contacting metal which would cause it.
If your audio cables are too frayed or cut and touching metal, or are too close to power wire that will cause it.
