Typically, fairing motorcycle sound systems are built on bikes that have a large fairing. They generally consist of marine stereos with waterproof speakers, which are cut into the fairing in factory-specific places or added by the dealers. In general, companies that produce bikes with built-in sound systems buy the most cost-efficient systems in bulk, then install this stock system on the bikes. Just as with other stock systems, there are better fairing stereos and speakers available for upgrade or self-installation. Check out Adventure Harley-Davidson, The Bikers’ Den, and Cycle Accessory Store for the best fairing sound systems.
