Rockville 6.5" Marine Speakers RMSTS65W 2-Way Waterproof

Rockville RMSTS65W are fully marinized 6.5" 2-way marine speakers that deliver loud, clear sound and weatherproof durability for boats and outdoor vehicles.

If you need dependable audio on watercraft, ATVs, or open-air vehicles, these Rockville speakers are engineered to perform where ordinary speakers fail. The pair combines a polypropylene mica-injected woofer and a 1" PEI dome tweeter to reproduce a wide frequency range with minimized distortion. Built to resist UV, salt, and moisture, the RMSTS65W units are meant to stay reliable in harsh outdoor environments while fitting common 6.5" mounting locations.

How do these speakers sound on a boat or open-air ride?

The RMSTS65W pair balances crisp highs and strong midbass so music remains intelligible even over wind and engine noise. Their 55Hz–20kHz frequency range and 91dB sensitivity help them project sound clearly at moderate to high volumes.

• 1" PEI dome tweeter for clear high frequencies and vocal detail
• Polypropylene mica-injected cone for controlled mids and punchy lows
• 91dB sensitivity helps efficient sound output from typical marine amplifiers
• CEA-2031 compliant power ratings: 100W RMS / 400W peak for realistic expectations

Will the speakers survive marine conditions and sun exposure?

Yes—these drivers are fully marinized to resist the elements commonly found on boats and off-road vehicles. Components are treated to fend off UV degradation, rust, and both salt and fresh water exposure, extending operational life in corrosive settings.

• UV-treated surfaces reduce yellowing and material breakdown
• Stainless steel terminals and rustproof hardware stand up to corrosion
• Molded ABS basket resists cracking from sun and vibrations
• Rubber surround offers flexible suspension in fluctuating temperatures

How easy is installation and what mounting should I prepare for?

Installation is straightforward for anyone familiar with standard 6.5" speaker cutouts. The speakers include pre-installed grills and mounting screws and fit compact mounting depths, making them suitable where space is limited.

• Fits a 5.43" cutout with a total diameter of 7.56" for face clearance
• Shallow 2.56" mounting depth for dash, door, or enclosure installation
• Includes grills and mounting hardware to streamline setup
• 4-ohm nominal impedance compatible with most marine amplifiers and factory radios

What construction features contribute to long-term reliability?

The RMSTS65W pairs rugged materials with smart engineering so they remain functional under vibration, moisture, and constant sun. Those elements combine to protect voice coils, suspension, and connection points during frequent outdoor use.

• Molded ABS basket resists impact and warping from heat
• Stainless steel terminals prevent electrical corrosion over time
• Rubber surround improves durability against UV and salt air
• Sea-ready design minimizes water intrusion into critical parts

Who is this for: These Rockville RMSTS65W speakers are a solid choice for boat owners, jet-ski and ATV riders, Jeep and convertible drivers, or anyone seeking weatherproof, high-output audio in outdoor applications. If you want a compact 6.5" setup with proven marine resistance, honest CEA-rated power handling, and easier installation in confined spaces, this pair delivers a practical blend of sound quality and durability without complex customization.
