Every quality audio company should have a marine audio line. After all, why deprive the marine audio industry of the same quality and innovative products that mobile audio products have enjoyed for years. In Florida it’s no secret why Sound Barrier has been a leader in the Marine Audio category for so long. We have taken our knowledge of the industry and our understanding of the corrosive and harmful conditions that living by the ocean has on electronic products and applied it to marine audio line.  By doing so, we have manufactured a marine audio product line that has been used and trusted in Florida and all throughout the Caribbean for years and years. The line includes patented items such as the MC-800 Weatherproof Marine Case. Weatherproof Speakers. Head Units and Complete Marine Stereo Combos.
