Our gauge tweeters are a snap to install, literally. Between the models of bikes that don't come with four gauges, along with the common desire to add more sound, it was about time we offered a solution. Each kit comes complete with our performance tweeters, crossovers, and necessary instructions. Other then the small amount of time for installation, nothing else is required.
