Just wondering is there anyway to get rid of that annoying sound. When I drive or rev my car you can hear it. I have 2 amps currently in my car. 1 for my speakers and 1 for my subs /w a capacitor. I'm pretty sure I did most of the wiring right. RCA cable is nowhere near the power cable. Both my amps are grounded and capacitor is grounded to bare metal. I even have noise suppressors on. Before the whining is so loud, but with it in, it dimmed down the whining a lot. The first part that annoys me even more is when I roll up my power windows I can hear it like whining even louder through my speakers. The second part is when I signal to turn left or right, the sound of the blinker is played through my speaker also with louder whining noise. Anybody knows the solution to this nuisance?

Professional detailed answers would be dearly appreciate. Don't give me that "It's your ground..." sort of bull answers. Thanks.
 
The number one reason for the whining is the rest of the car is grounded to the same place your radio/amps are so it picks up all the noise.

Run both the power and the ground directly to the battery, (make sure you properly fuse it), everything, radio, amps. Also do not ground your speaker wires to the car, they should be run from amp to speaker hot and ground, and that should stop all the noise.
