Aquatic AV makes some pretty comprehensive audio systems for a variety of outdoor applications including boats and, of course, motorcycles also. What’s great about their Ultra Package for Harley-Davidson is this. It gives a significant discount on all of the top-of-the-line Harley product-upgrades you’ll need for your ride.
This package includes the top-of-the-line MP5+ head unit for Harley, AD300.2 2-Channel Amplifier and the Sport Series 6.5” Speakers. Check out the full H-D audio setup here.
