Loudness != quality
Actually, that is wrong, from a subjective point of view Smile | :)

It is well known that if you set up two 100% identical systems, but adjust one to play 1 to 2 dB louder than the other, in a blind test a listening panel will not hear the loudness difference, but will describe the louder system as having a firmer bass and a more distinctive upper middle range.

The salesmen know that very well. Notice that when you are out shopping for a new stereo system, speakers or whatever, the salesman presents the more expensive alternative (i.e. the one he want to sell), he cranks up the level a little tiny bit when he tells you to listen closely for the bass clarity, or the middle and upper range quality.

Many years ago, there was a craze in the HiFi world about green felt tip pens: You could buy these super expensive pens to color the edges of your CDs to improve the sound quality. You had to use these special expensive pens: They were the exact complimentary color to the infrared laser. (Green being a complimentary color of IR????)

One of my friends, an electronics engineer, laughed wildly about this. But as a scientist, he wanted to verify that it was plain BS. So he made a setup with two CD players to the same amplifier, same speakers, and two identical copies of the same CD, except that one had its edge painted with this super-expensive green felt tip pen. When he switched between the two inputs, changing nothing else, he was slightly shocked: The green-painted copy certainly did sound firmer in the bass, and more distinct in the upper middle tones.

He knew that it was crazy, it couldn't be the case, and set out to find the explanation. As an EE guy, he had available all sorts of meters, and it didn't take him long to discover that the output from the CD player with the "green" CD was slightly more than 1 dB higher than the other one. 1 dB is not discernible as a loudness difference. He added a small resistor to the cable, to bring the signal level down to that of the other CD player. Now it impossible to distinguish about the two CDs. The subjective difference was solely caused by the very slight loudness difference, not perceived as such.

This little experience suggested an obvious verification test: He removed the level correcting resistor, but switched the CDs in the players: Now the un-green CD was in the player with the higher signal output, the green in the one with the lower signal. Now the un-green CD was the one with the firmer bass and the more distinct middle range.

So, if your car stereo really isn't that good: Crank up the volume, and it might sound a lot better.

Bonus story: When I was considering buying a Ford Transit box car (I did end up with one!), the salesman let me test drive a used Transit, for which they already had a buyer so it wasn't available: The buyer wanted it to give room for his bass speakers, that wouldn't fit into any sedan. He needed a Transit size car to fit his speakers in!
