   As far as the problem occurred, I agree that messing with the ground
wires in eliminating the noise.  Either ground all the components in the
system at the same point, or ground them in a series (i.e., ground the
equalizer to the stereo, and then ground the stereo to some good ground
point.)  Make sure you aren't grounding to a painted surface.  When you
flip your headlights on, they are grounding out, and you are setting up
a possible ground loop, which can reck major havok on the noise in your
system.  Try grounding the stereo on the chassis, or if possible directly
to the negative post of your battery.  Also, the use of a capacitor across
the positive and negative leads (make sure the capacitor is of 50 volts
or more).  Noise in car stereo is an incredible pain, and nothing short
of trial and error will eliminate it.
