There is one serious aspect of car audio that is very much a pro topic, for
the same reason many studios have Aurotones as secondary monitors.
Whether in recording, commercial production, or broadcast, audio processing
more often than not needs to put more emphasis on impact to listeners with
bad quality car systems in noisy environments (as well as blue light special
stereos at home) than it can devote to clean systems operated with surplus
dynamic range in quiet homes.
In broadcast, that leads to two kinds of loudness wars. One often results in
aggravated distortion, and overdeviation of some FM IFs. Many FM programmers
are technically illiterate enough to think that overmodulation makes for a
less noise prone signal, without understanding the Bessell functions or
clearly grasping mulitpath concepts. (Yes, you need at least one or two
levels of math beyond integral calc to clearly understand basic audio
concepts.)
The other kind of loudness war is valid. That's the one where you try to
crunch the signal enough so that a 4 watt amp driving 88 dB efficiency
speakers can produce commercials audible over 75-80 dB spl of road, vehicle,
and wind noise, preferably without driving the amp much over 10 or 20%
distortion.
