Our true marine-grade speakers have a composite basket, aluminum dome tweeter, chrome-plated poly mid-range speaker, suspended tweeter design and an easy mount grill. They also feature a built-in plug-and-play RGB LED illumination system with an RF remote, so you can completely control your LED system wirelessly. Not only will these speakers get the party going, they'll add a fun element with the multi-color LED system. And with the easy mount grill and shallow 2.5-inch mounting depth, they are a perfect and easy install or nearly any boat.
