Portable MP3 question

Will playing an mp3 player through my input jack in the front of my car
cd player have the same sound quality as a regular cd? Is the signal
to
noise ratio pretty much the same? Just curious.
What about playing it through an fm transmitter to my car stereo?

An mp3 is a compressed format, which means that some (or a lot) of the
data
needed to reproduce the sound is not present. That being said, if you
encode
your mp3s at a high enough bit rate (and thus higher quality) you may
not be
able to tell a whole lot of difference, particularly considering that
car
audio is generally not state of the art, esp. compared to the quiet
listening room you may be in at home.

I play mp3s through my home stereo sometimes, and the quality is
certainly
acceptable. However, the sound is also degraded somewhat by the fact
that
I'm (and you will be) running the headphone out to the line in of my
stereo
(impedance mismatch?).

The signal to noise doesn't seem to suffer, from my experience.

After you throw in the road and engine noise, none of the impedance
mismatches or MP3 compression artefact is going to matter. From my own
experience listening to an MP3 player exactly like OP does, I can tell
that there is no audible difference whatsoever between the CD and the MP3.
Rock and audio books are absolutely fine; classic music will suffer from
the road noise.
