    My car was parked, but running, this morning and it was just fine. i came out of the car to drop my son offf and come back to hear the dreaded alternator whine. [​IMG] this is very weird how it just popped up out of no where while the car was running. mind you, i've had my system exactly like this for 2 years.

    it's not there when the car is off, it increases and decreases with engine acceleration/deceleration. i've checked my amp wiring and it SEEMS ok...but i don't think that would be it since i don't get the noise when the car is off.

    what do you think it is? how can i fix it?

    Could be bad/pinched RCA's.

    You need to go through an elimination process.

    Do all of this with the car on, and with enough volume to hear the whine.

    Unplug your RCA's at the amplifier. If the sound goes away, it's either the HU or the RCA's (more than likely RCA's). If the sound is still there, it's the amplifier.

    Come back and let us know what happened.

    Though power cables shouldnt induce whine, I found that in my truck it did and only when the amp's power cable was drawing a lot of current. I was also useing very cheap RCA's. Try to diagnose the source of the noise like noah said and also let us know what equiptment you have.
