Music will sound its best with GM Genuine Parts Car Speakers, and are GM-recommended replacements for your vehicle's original components. These speakers are designed, engineered, and tested to rigorous standards, and are backed by General Motors. 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. The voice coil will form a north and south pole that will cause the voice coil and the speaker cone to move in relation to the permanent magnet. The current delivered to the car speaker is rapidly changing alternating current (A/C). This causes the speaker cone to move in two directions, producing sound. GM Genuine Parts are the true OE parts installed during the production of or validated by General Motors for GM vehicles. Some GM Genuine Parts may have formerly appeared as ACDelco GM Original Equipment (OE).
