The Alpine TuneIt App is an easy-to-use sound-tuning app that also offers Facebook notifications. Download the free app onto your iPhone or Android smartphone and create a user profile about your vehicle and Alpine sound system. Follow the simple graphical instructions to adjust sound settings for your specific vehicle or choose from pre-made settings in the database. Settings that can be adjusted include Time Correction, Parametric EQ, Crossover, and Media Xpander. You can make and save up to 100 different sound settings in your account, which is helpful if you want various settings to use for specific types of music. Share your settings and get rated on your tuning skills, plus try out and rate settings made by others. The more active you are, the higher your profile status progresses within the app.
