Package Includes: (2) pairs Rockville RMSTS65S 6.5" waterproof coaxials (800W system total), (1) pair RWB90W 8" 360° swivel wakeboard tower speakers, Rockville RXM-S6 6-channel marine amplifier (Dyno-certified 660W RMS / 2,600W peak) with status LED, and the RMWK4 true marine 4-AWG amp install kit-complete wiring and hardware included. Built for the Water, Built to Last: All speakers are fully marinized and completely waterproof/rustproof with UV-treated housings, stainless hardware, rubber-gasketed terminals, and molded ABS baskets for fresh or saltwater use season after season. Loud, Clean, and Controllable Output: RMSTS65S coaxials deliver punchy mids and crisp highs; RWB90W 8" towers add long-throw projection. RXM-S6 provides adjustable 12dB HP/LP crossovers, 0–12dB bass EQ, and bridgeable channels for flexible 6/4/3-channel setups-including subs. True Marine-Rated Amplifier with Smart Extras: Conformal-coated PCB, stainless screws, dual 60A fuses, 8-V preamp stage, and full IC protection. Included PA mic with music-ducking for clear announcements and remote bass knob for on-the-fly low-end control. Hassle-Free Installation and Guaranteed Performance: RMWK4 kit supplies 4-AWG power/ground, marine RCAs, remote lead, speaker wire, Mini-ANL fusing, and stainless hardware. CEA/Dyno-honest ratings, rigorous QC, and Rockville’s hassle-free warranty for peace of mind. Outfit your boat with a complete, matched system that’s engineered for the water and tuned for fun. This Rockville bundle combines two pairs of RMSTS65S 6.5" waterproof coaxials with a pair of RWB90W 8" 360° swivel wakeboard tower speakers and the RXM-S6 6-channel marine amplifier, delivering room-filling sound at the dock and long-throw projection for riders behind the boat. The included RMWK4 marine 4-AWG install kit provides everything needed for a safe, tidy wiring job.

Every component is fully marinized to handle salt, spray, UV, and vibration. The RMSTS65S speakers use polypropylene cones and rubber surrounds inside molded ABS baskets for reliability and accurate response, while the 1" PEI dome tweeters add crisp detail. The RWB90W towers pair polypropylene/mica cones with Santoprene surrounds and a built-in 2-way crossover, then mount on reinforced nylon brackets that rotate a full 360° so you can aim sound fore or aft.

Power comes from the RXM-S6, a true marine amplifier with a conformal-coated PCB, stainless hardware, and robust 2×60A fusing. Its high-speed MOSFET design, selectable HP/LP crossovers, bass EQ, and bridgeable architecture let you run 6 full-range channels, 4 channels plus a bridged sub, or 3 high-power zones. A thoughtful touch for captains: the included PA microphone automatically ducks music for clear announcements, and the remote bass knob lets you trim low end on the fly.

Installation is straightforward thanks to the RMWK4 kit’s tinned wiring, Mini-ANL fuse holder, RCAs, remote lead, and stainless hardware. With CEA/Dyno-verified power ratings and Rockville’s stringent quality control, this system delivers the honest output, durability, and flexibility boaters demand-season after season. Plug in, power up, and bring concert-level sound to open water.
