Rockville 6.5" Marine 2-Way Speakers RMSTS65B 800W

Rockville RMSTS65B are marinized 6.5" two-way speakers built for boats and outdoor rigs, offering waterproof construction, UV resistance, and robust 800W peak audio performance.

Designed specifically for saltwater and freshwater environments, the RMSTS65B pair combines weatherproof engineering with components tuned for clear highs and substantial low-end impact. These speakers use a polypropylene mica-injected cone and a 1" PEI dome tweeter to produce a wide 55Hz–20kHz frequency response while stainless steel terminals and a protective UV coating keep corrosion and sun damage at bay. Whether you’re outfitting a boat, ATV, Jeep, or backyard audio setup, the RMSTS65B aims to deliver dependable sound and long-term durability.

How do these speakers handle marine conditions?

The RMSTS65B are fully marinized, meaning each component is selected and treated to resist moisture, salt, and UV exposure. Corrosion-prone parts are replaced with stainless steel, and the enclosure and cone surfaces are finished with UV-blocking materials to slow sun degradation.

• Fully waterproof construction for salt and fresh water exposure
• Stainless steel terminals to prevent corrosion
• UV-resistant coating on grills and surrounds

What kind of sound quality and power output can I expect?

These two-way speakers provide a balanced presentation with crisp highs and solid mid-bass thanks to the PEI dome tweeter and polypropylene mica-injected cone. Rated at 800W peak (100W RMS, CEA-compliant), they offer temporary high-output capability while the RMS rating indicates steady continuous power handling.

• 1" PEI dome tweeter for clear high frequencies
• Polypropylene mica cone and rubber surround for controlled bass
• Frequency range of 55Hz–20kHz for broad musical coverage

Are they easy to install in boats, cars, or ATVs?

Installation is straightforward: speakers ship with pre-installed mounting screws and grills to speed setup. The physical dimensions are optimized for common 6.5" cutouts, and the shallow mounting depth fits many dash and enclosure locations where space is limited.

• 5.43" cutout diameter fits most 6.5" standard mounts
• 2.56" mounting depth for tight installation spaces
• Included pre-installed screws and grills simplify mounting

What certifications and standards back the performance?

Rockville provides CEA-compliant ratings to ensure power and performance numbers are reported consistently and reliably. That transparency helps buyers compare these speakers against other brands that might use non-standard peak claims.

• CEA 2031-compliant ratings for trustworthy specifications
• 4 ohm impedance for compatibility with most marine amplifiers
• Manufacturer-tested frequency and power specifications

Who is this for? The RMSTS65B pair is aimed at boat owners, powersports enthusiasts, and anyone who needs compact, weatherproof speakers that don’t compromise on sound. If you want speakers that tolerate sun, spray, and salt while delivering reliable, CEA-verified performance in a shallow mount form factor, these are a solid choice. They particularly suit DIY installers updating factory systems on boats, ATVs, Jeeps, or outdoor entertainment areas where exposure and space constraints matter.
