Category: Marine Speakers
Check Current PriceChoose the Rockville bundle: (2) RWB90B 8-inch speakers, RXM-S6 amp, and RMWK4 wiring. It provides marine rated hardware, a 4 AWG power kit, and swivel wakeboard speakers. This package suits Marine Speakers installations on boats and small off road rigs.
When to Choose the Rockville RMWK4/RXM-S6 Bundle
The Rockville bundle: (2) RWB90B 8-inch 300W wakeboard swivel speakers + RXM-S6 2600W 6-channel amp + RMWK4 4 AWG marine install wire kit + (2) MRCA20 Marine Speakers fits when you need rugged, high-output sound on exposed vehicles. Marine Speakers in this package include UV-resistant nylon mounts, sealed gaskets, and stainless terminals to resist salt and spray. Choose this kit when you require swivel speakers for adjustable coverage and a conformal-coated amplifier for corrosion resistance.
- RXM-S6 peak power: 2600W; dyno-certified RMS: 660W
- RWB90B pair peak power: 300W; pair RMS: 200W
- RMWK4 includes 4 AWG power cable, twisted RCA, marine-grade speaker wire, waterproof fuse holder
The Rockville RXM-S6 + RWB90B + RMWK4 bundle also simplifies installation by supplying appropriately sized power cable and a waterproof fuse. Installers get 4 AWG power conductors that reduce voltage drop on high-current systems and prevent heating. Use 16 AWG wire (thicker gauge for better signal) for speaker runs under 20 feet and 14 AWG for longer runs to limit loss. That wiring strategy ensures stable amp performance and consistent volume while underway.
What vehicle and environment conditions justify this choice?
RXM-S6 provides 660W RMS to drive speakers loudly without clipping. That level suits open air boats, wakeboarding with high wind, and off road Jeeps with added road noise. Use this Rockville Marine Speakers Bundle when you require clear midrange above 85dB at ten feet and reliability under constant spray. Choose these components rather than consumer car speakers when salt, UV, and vibration threaten standard hardware.
Deciding if a marine or off-road amp and speaker kit
Rockville bundle: (2) RWB90B 8-inch 300W wakeboard swivel speakers + RXM-S6 2600W 6-channel amp + RMWK4 4 AWG marine install wire kit + (2) MRCA20 Marine Speakers makes sense when mounting points and vehicle electrical capacity match the kit. Evaluate available battery capacity, alternator output, and physical mounting clearance before buying. The amp s conformal-coated PCB and stainless hardware provide moisture and salt resistance you want for boats or open air vehicles. Factor in speaker swivel brackets when planning coverage and cable routing.
Vehicle compatibility checklist and electrical readiness
- Alternator recommendation: 100A or larger for sustained high-volume operation, or add a secondary battery.
- Power cable: use the included 4 AWG for battery-to-amp runs; never substitute thinner gauge for that length.
- Speaker wiring: use 16 AWG for runs under 20 feet; use 14 AWG for longer runs to maintain signal.
- Mounting: confirm tower or roll cage mounting radius and cutout depth before ordering speakers.
- Grounding: connect amp ground to battery negative or a known clean chassis ground to avoid noise.
How do power, impedance, and weather ratings affect fit?
RXM-S6 supplies bridgeable outputs that match speaker power handling when wired correctly. Compare amplifier output, speaker RMS ratings, and wiring gauge to prevent overheating or distortion. The following technical specifications clarify compatibility and safe operation.
- RXM-S6 dyno-certified RMS: 660W (total)
- RWB90B pair RMS: 200W; pair peak: 300W
- RMWK4 cable: 4 AWG power, marine-grade speaker wire, waterproof fuse holder
Impedance matching (ensures amp and speakers work together) prevents mismatched loads that cause amp protection trips or speaker damage. If you bridge channels, verify the amp s minimum bridged impedance and wire speakers accordingly. Protect connections with stainless hardware, dielectric grease on terminals, and proper fusing to maintain longevity in wet environments.
Best scenarios to use Rockville RMWK4/RXM-S6 Bundle outdoors
Rockville bundle: (2) RWB90B 8-inch 300W wakeboard swivel speakers + RXM-S6 2600W 6-channel amp + RMWK4 4 AWG marine install wire kit + (2) MRCA20 Marine Speakers performs best on wake towers, pontoon boats, dune buggies, and Jeeps with roll cages. These systems tolerate UV exposure, spray, and constant vibration better than standard car audio. At a price of $299.95, the kit represents a budget-friendly, full-system option compared with Wet Sounds or JL Audio tower systems.
Marine speaker and amplifier bundle with 4 AWG install kit and wakeboard swivel speakers suits owners who want plug-and-play value and weatherproof components. The swivel brackets let you aim sound toward wake riders or the cockpit, improving perceived volume without extra power. For home dock parties or beach days, these speaker systems deliver wide coverage while resisting corrosion when installed correctly.
Which installation scenarios need corrosion and vibration proofing?
RWB90B resists corrosion using stainless terminals and sealed gaskets. Installers must use stainless fasteners, marine-grade lock washers, and dielectric grease on terminals to prevent galvanic corrosion. Secure the RXM-S6 6-channel marine speaker system with vibration-damping mounts and keep RCA runs twisted and away from ignition noise sources. Do you need an added battery? Yes add a deep-cycle or cranking battery for long listening sessions if alternator capacity falls below 100A. How do you avoid ground loop noise? Tie the amp ground to the battery negative and use twisted RCA runs to reduce interference.
Follow-up searches readers might make include: “What fuse rating for RXM-S6 main power?” and “Can RWB90B swivel speakers mount on any tower?” For fuse rating, use the amp manual or consult Rockville specs, typically matching manufacturer-recommended main fuse size near the battery. For mounting, confirm cutout depth and mounting clearance before purchase; the swivel brackets help many towers but verify dimensions where possible.
