It's the 90 minute length that's keeping you from putting it all on 
one CD.  Can't get more than 79:59.  (And if it was for replication, 
it's not a good idea to go beyond 76 minutes.)  However... one thing 
you could do is to save your original AIFF as a 16-bit, 44.1 kHz mono 
file.  Split the track in half and re-import the file into a stereo 
editing program or DAW... put the first half of the speech on the 
left side and the second half on the right.  Burn a disc.  When you 
listen, just flip the balance of your car's playback system hard-left 
or hard-right.  Time to test your system's stereo crosstalk, eh? 
Otherwise, I think you're stuck with using two discs.  Unless you 
wanted to burn it as an mp3 CD.
