We don t simply use car audio speakers with a new sticker & call them bike speakers. These are the real deal & once you put them in you ll be blown away. These speakers are weather-proof, high-efficiency coaxials specifically created as fairing drop-ins or as replacements for rear speakers on Victory bikes equipped with stock speakers. Extremely powerful, these 4 ohm speakers are lighter than anything on the market. These speakers leave the competition stuck in the dark ages with the same old heavy & dull sounding speakers.
