Read my previous reply to this. The only effect the noise eliminator could possibly have is to restrict the current flow into the head unit. This, in turn, can effect the dynamic range of the power amplifiers driving the speakers (if the amplifier is indeed in the head unit itself, and not outboard).
When you go from a quiet to a loud passage in music, or play a big bass note, or have a sharp drum hit, the power sent to your speakers jumps from a small value to a large one. For example, it could jump from 0.1 watts to 40 watts. This power doesn't come free, so the amplifier gets it from drawing more current on it's 12 volt input side.
The noise eliminator limits how fast the amplifier can get the extra current it needs. In effect, the amplifier now sounds softer, or muddy. Depending on what type of music you listen to, how loud, how good you ears are, and how "picky" you are about your system, you may or may not hear this effect. With the built-in amp most head units have, you may not hear it anyway, as they are pretty limited in their power output to the speakers, and therefore their power input requirements are fairly small.
Clear as mud?
