[QUOTE="huberoy123, post: 8526140, member: 658561"] Make sure that the ground wire for the pioneer head unit and power amp are connected to the car separately with different screws. Ground loop adapters can help in some instances. However, they can downgrade your sound. I had a similar problem in my daughter's car, and tried the ground loop adapters. They helped some, but the problems was ultimately resolved after I installed new coil on spark plugs and new alternator. I think that the alternator had a bad diode, which caused the engine whine.
