LOUD! Stylish! Rugged! Producing an earsplitting 120 decibels of sound, the Sound Bomb is 4 times louder than a standard motorcycle horn & twice as loud as a standard car horn! The DENALI™ Sound Bomb was designed for those who want to be heard, but still want to maintain a stylish look. Thanks to its compact design & blacked-out housing, the Sound Bomb will practically disappear once installed. The unique design of the DENALI compact horn features a rugged molded clamp that mechanically mates the compressor to the acoustic unit. This makes the Sound Bomb virtually indestructible, even in high vibration applications. Compatible with all CANbus electrical systems.
