Put the JBL BassPro SL under your car seat and bring your music to life. This compact and complete subwoofer system consists of an 8-inch woofer and a powerful, 125-watt amplifier. Connect the BassPro to your radio and enjoy a fuller sound with deep bass. Don't have space underneath the chairs in your car? In that case, position the subwoofer in the trunk. Thanks to the RCA connectors, you can also connect a car radio without special subwoofer plug to the BassPro SL.
