The Rockford Fosgate RFD-3218 is an impressive 18″ Sub only to be used for those impossible missions. The sub is so powerful running at 1000 Watts RMS and peaking out at 2000 Watts that it can on it’s own in a single installation provide a mesmorizing amount of bass. This massive subwoofer weighs 60 lbs on its own and is no lightweight contendor.
