JBL Car Subwoofer - GT-BASSPRO12

The easiest way to add high-output, low-distortion bass to any car audio system is with the JBL® GT-BassPro12 – a powered subwoofer that pumps out car-rocking bass through a design so cool you won’t want to hide it in your trunk. Simply put, it’s a complete subwoofer system for your vehicle. Its patented Slipstream port design delivers deep, bottom-end bass while minimizing port noise. Its woofer features improved motor-structure venting for thermal protection and a progressive spider to ensure superior mechanical reliability even at the highest output levels. Its amplifier delivers maximum power and the flexibility to connect to any factory-installed or aftermarket head unit. And with the system’s included remote level control, which lets you adjust the bass level from the driver’s seat, the only time you’ll need to stop is for gas.
