Reverse/Accelration Noises
 

Many cars have a similar problem.
I have always found bad/weak grounds in the aftermarket stereo deck installs.
A weak ground and shotty wiring will cause you speakers to make this noise, many times with the stereo off. A good way to check is disconnect the stereo or speakers from you car and see if the problems gone.

Be sure to post again if this is your problem.
I am curious and I'm sure others are as well.

Might be clutch release bearing also called clutch throwout bearing, when pushing clutch while stoped with engine running does noise change?:confused:
