Music will sound its best with ACDelco GM Original Equipment Car Speakers, and are GM-recommended replacements for your vehicle’s original components. Speakers turn electrical energy into mechanical energy to move air, using a permanent magnet and an electromagnet. The electromagnet is energized when the radio or amplifier (if equipped) delivers current to the voice coil on the speaker.
