Kevin's right. Never underestimate the subjectivity of your ear/brain
receiver, both the physical and psychological aspect. In the last six to
eight months, due to neighbour complaints, I've been listening to music
and monitoring at much lower levels. Surprisingly, I find my perception
of "loudness" is much more sensitive, and my "internal" dynamic range is
much increased. Another thing to consider is the environment: did you
change anything inside your car recently, which might have been
absorbing low frequencies? If in doubt/curious, you could always run a
sine sweep through your system and see if something odd comes up.
Finally, make sure you don't have bass boost turned on by mistake! :)
Seriously, though, you'd be amazed at how many listening systems have it
turned on by default. I have a pair of (otherwise decent) little
speakers which insist on toggling bass boost on whwnever switched off
and on again.
