Seaworthy Marine Audio: Built for the Open Water Since 1986

When it comes to audio equipment engineered specifically for the marine environment, Seaworthy — the consumer-facing line of Prospec Electronics Inc. — has been a trusted name on the water since 1986. Headquartered in Mount Pleasant, South Carolina, Prospec Electronics has spent nearly four decades focused on one mission: bringing high-performance, durability-tested audio solutions to boaters who refuse to compromise on sound quality.

A Harman International Partnership That Sets the Standard

What truly distinguishes Seaworthy in the marine audio world is its long-standing partnership with Harman International, one of the most respected names in consumer and professional audio. Through this relationship, Prospec Electronics serves as the dedicated marine channel for the legendary JBL and Infinity audio lines — brands synonymous with acoustic clarity, power, and engineering excellence. Boaters benefit from world-class audio technology that has been purpose-built and rigorously adapted to withstand salt air, UV exposure, moisture, and the constant vibration of life on the water.

A Full Ecosystem of Marine Audio Products

Seaworthy’s product lineup is designed to cover every component of a complete marine audio system. Whether you’re outfitting a center console, a pontoon, or an offshore cruiser, Seaworthy offers the building blocks you need. At the heart of any great system is a quality marine speaker — and Seaworthy delivers coaxial and component options engineered to project clear, powerful sound even in open-air cockpit environments where wind and engine noise are constant challengers.

Equally important to a reliable marine audio setup is proper signal reception. Seaworthy’s lineup of AM/FM stereo antennas are crafted to pull in clean, interference-free broadcast signals even when you’re miles from shore. For boaters who want a broader selection of marine antenna options, additional AM/FM stereo antennas are available across a range of mounting styles and configurations to suit virtually any vessel.
