Product Description

This four-piece marine kit pairs in-hull and tower speakers with a four-channel amplifier and waterproof wiring. It includes a pair of Rockville RMC80B 8" 800W flush-mount marine speakers, a pair of RWB90B 8" 300W wakeboard tower speakers with 360-degree swivel brackets, a KRYPTON MF4 2400W peak / 600W RMS four-channel marine amplifier, and the RMWK4 waterproof wiring kit.

The RMC80B speakers deliver 100W RMS each with a polypropylene cone and 0.5" polymer tweeter for strong low-end and clear highs. The RWB90B tower speakers step up to 8" drivers at 200W RMS each, with 1" polyimide dome neodymium tweeters and 1.25" Kapton voice coils for high SPL output at 98dB sensitivity. Nylon brackets reinforced with embedded steel fit bars from 1.26" to 2.87" and rotate a full 360 degrees. The KRYPTON MF4 amplifier drives all four speakers with independently adjustable crossovers per channel, a digital voltage display, and a marine PA system with talkover functionality. Every electronic component is conformal-coated and housed in a rustproof aluminum and stainless steel chassis. The RMWK4 wiring kit completes the install with 4 AWG tinned-OFC cables and a waterproof fuse holder.

Features

    • Matched 8" In-Hull and Tower

      8" flush-mount speakers cover the cockpit while 8" tower speakers with 98dB sensitivity push audio to riders and swimmers at distance.

    • 360-Degree Swivel Brackets

      Steel-reinforced nylon brackets rotate a full 360 degrees, letting you aim tower audio in any direction from the helm or swim platform.

    • Four Independent Crossovers

      Each channel on the KRYPTON MF4 has its own adjustable crossover, so you can tune flush and tower speakers to different frequency ranges.

    • Marine PA with Talkover

      A PA microphone plugs into the amp and automatically dips the music volume when you speak, handy for anchoring or docking callouts.

    • Rustproof Marine Chassis

      Conformal-coated PCB, aluminum heat sink, and stainless steel end panels and hardware keep the amplifier operating after years on the water.
