Driving speakers?

How do I drive speakers? Like, if I just soldered a cable and a jack onto a speaker, would it work? Or do I need some kind of circuit to go along with it? 
Many thanks,
Zem.

depends on the speaker. if the speakers are small enough (think headphones or those speakers from the dollar tree) you can usually drive them without a pre amp or amplifier. If you are dealing with larger speakers, you will need to use an amplifier

Thank you both! I can't choose best answer for both questions... But both helped a bunch.

The music will play if you wire the speakers directly to a jack, it just won't be that loud (assuming you are using an ipod, computer, CD player...). If you want to be able to listen at normal volumes you will need an amplifier.
