To increase the longevity of wakeboard boat tower speakers, it's important to lightly rinse them with fresh water after each use to remove any salt or dirt buildup. You should also avoid exposing the speakers to excessive heat or direct sunlight, and periodically check the wiring and connections for signs of wear or corrosion. Some manufacturers like Wet Sounds and JL Audio also sell 'socks' that you can wrap your speakers with when you're not on the water. We recommend purchasing them and keeping your speakers wrapped during the off season and when your boat is not in use.
