Most car audio subwoofers are installed in the trunk due to space limitations in the cabin of the car. Subwoofers are usually 10 inches or 12 inches in diameter although they can be as big as 34 inches and as small as 4 inches. Car audio subwoofers can add more depth to a car audio system by reproducing frequencies below 150 hertz. A subwoofer can add strong and powerful basses to your car audio. Wider subwoofers allow for more efficient air displacement which is critical for low frequencies.

The amplifier for car audio subwoofers can be integrated into the cabinet or installed as a separate unit. The amplifier should have an electronic crossover to filter out high-frequency sounds before the signal is passed to the subwoofer.

Although car audio subwoofers are usually round in shape, recently manufactures have been introducing subwoofers in new shapes. Square subwoofers have been released by Stillwater Designs and other companies have introduced triangular and hexagonal subwoofers. For car use, the most practical type of enclosure is the sealed enclosure because it requires the minimum space and matches the audio requirements of a typical car interior.
