Music will sound its best with ACDelco GM Original Equipment Car Speakers, andare GM-recommended replacements for your vehicles original components.Speakers turn electrical energy into mechanical energy to move air, using apermanent magnet and an electromagnet. The electromagnet is energized when theradio or amplifier (if equipped) delivers current to the voice coil on thespeaker. The voice coil will form a north and south pole that will cause thevoice coil and the speaker cone to move in relation to the permanent magnet.The current delivered to the car speaker is rapidly changing alternatingcurrent (A/C). This causes the speaker cone to move in two directions,producing sound. These original equipment car speakers have been manufacturedto fit your GM vehicle, providing the same performance, durability, andservice life you expect from General Motors.
