With the JVC CW-DRA8 you create a club system on wheels. This compact 8 inch subwoofer is easy to place under the passenger seat in your car thanks to its size. This means you do not have to sacrifice your trunk or back seat. With the supplied remote control you set the volume and the crossover frequency. This allows you to easily integrate the subwoofer with your sound system. By setting the crossover frequency, you determine the frequency from which the subwoofer produces the bass. This helps you to find the balance between the low frequencies and the speakers.
