APBMW S8-2.2 Subwoofer Driver | 300 W Peak Power | 200 mm | 2 ohm

The 200 mm (8 in.) APBMW S subwoofers allow a direct replacement of the OEM speakers underneath the front seats, making the most of the factory acoustic load and generating deep and crisp low frequencies. The Neodymium magnet allows for greater power and control than ferrite while maintaining the depth of installation unaltered.
