I've searched this newsgroup using Google Groups, and I have read
multiple posts about turning off the "Loudness" feature on headunits.

What about the option "S-HDB" (Super High Definition Bass) that is on
most, if not all, new Panasonic headunits? "S-HDB" allows you to
choose from "Tight", "Boom", and "Off"? Which setting for the "S-HDB"
control would be recommended for optimal performance and tuning?

I have 2 Polk MOMO 4x6 component plates in the front doors, and 2
Boston Acoustics NX97 6X9 3-way speakers in the rear working with a
Panasonic headunit (CQ-DF783U) along with a 200 Watt 4-Channel MTX
amplifier.

There is no setting for "optimal performance and tuning". The options are
there for the user to set the way it sounds best for them in their
particular car.

I realize that, but I want opinions on which setting for "S-HDB" would
have less distortion. Like I explained in my initial post, I read that
the "loudness" option is frowned upon, but I want to know if the
"S-HDB" option is as well.

It really depends on your definition of "optimal performance and tuning".

If the smiley face eq appeals to you, crank it. If not, turn it all the
way off.

That's silly, especially for a car. It's boosting the bass at low
volumes where road noise would normally drown it out. If the loudness
compensator sounds bad, you may have mismatched the gain between the HU
and the external amps. Turn up the volume - The amp gains are too low
if the bass cuts out or too high if the bass is overwhelming. It should
be a transparent feature. Some HUs have tunable loudness parameters.

Try them out.

That's all great, but the acoustics of a car are terrible. You probably
will want some kind of EQ system to make it sound better.
