The premium sound speakers are much nicer. They have a nice big magnet on them where as the normal speakers look very [censored] and cheap. I just upgraded to premium sound (found some speakers in a Mystique in a salvage yard.) They sound much nicer and cleaner than the other speakers. You could always unscrew the speaker and look on the back of the speaker. If you see a big magnet then you have it. Atleast, i think thats what premium sound is.
