I'm a bit of a music nut, and I'm in need of a new stereo setup in the Corolla. The early 90s head until that was installed a deacde ago is no loger cutting it.

I know very little about car audio, but I have an idea of what I like.

As far as music I prefer clarity to loudness and I could careless about having a giant sub making my old crappy car rattle and vibrate like it's in the midst of an earth quake. If it's at all possible I'd like some of the audio guys to suggest some set ups (speakers, head units, (Do I need an amp?)) that are going to give me a semi-loud set up, that's going to be extremely clear. I don't want anything out rageous just something loud enough to drone out the wind when the windows are down, and still sound decent.

ah and I'd like to know of good MP3 head units

The car is an 86 Toyota Corolla GT-S, and I have no idea what size speakers it uses. (I kinda go into audio places and point at stuff).

Any help from you audio guys out there would be greatly appriciated...
