Well, my dad has a 2004 Grand Prix, and my mom has a 2006 Grand Am GT, I believe. She has a MP3-CD capable player, but only holds 1 CD, and doesn't have as nice a sound system in car as my dads, which is a 6 CD changer with monsoon subs in the back. My mom hates anything but the crappy commercial rock the radio plays, but my dad will let us listen to anything. Plus, he has the bass cranked. He used to play bass in a local band for a while, so he liked to be able to hear the basslines in his music. My mom's car has the usual smiley face setting for the EQ, but it's one of those default settings that blows, period.
