When you move to a 12-inch driver on a motorcycle, you are looking for more than just sound—you are looking for displacement. This subwoofer features a high-temp voice coil and a reinforced weather-resistant cone, ensuring that it can handle the intense thermal cycles and vibrations of a frame-mounted installation. The Dual 4-Ohm configuration provides maximum wiring flexibility, allowing you to bridge a high-output amplifier to 2-Ohms for maximum power delivery.
