LOUD! Stylish! Rugged! Producing an earsplitting 120 decibels of sound, the SoundBomb is 4 times louder than a standard motorcycle horn and twice as loud as a standard car horn! The DENALI™ SoundBomb was designed for those who want to be heard, but still want to maintain a stylish look. Thanks to its compact design and blacked-out housing, the SoundBomb will practically disappear once installed. The unique two piece design of the DENALI split horn separates the compressor from the acoustic unit allowing the horn to be installed in tight spaces like behind motorcycle body panels. A 48 inch heat resistant air hose connects between the two halves allowing you to mount them in an entirely different location on your bike without sacrificing any sound output.
