- Package Includes: (1) Pair Rockville RWB90B Black 8" 300w Marine Wakeboard 360° Swivel Tower Speakers, (1) Rockville DBM25 1500w Peak/370w Dyno-Certified RMS Class-AB 2-Channel Marine Amplifier With Terminal Covers, (1) Rockville RGHR2 Marine Gauge Hole Receiver w Bluetooth USB, Radio + Wired Remote, (1) Rockville RMWK4 4 AWG Gauge Waterproof Marine Amplifier/Amp Install Wire Kit
- Marine-ready performance: RWB90B two-way 8" tower speakers cut through wind and water with a polypropylene cone, Santoprene surround, and 1" polyimide dome tweeter. Built-in crossover shapes clean highs and solid midbass for riders and passengers. Fully marinized components, sealed terminals, and stainless hardware resist salt, spray, and UV. Impedance 4 Ohm, Frequency Response 60-20kHz, Sound Pressure Level 98dB. Ideal for wakeboats, pontoons, and open cockpits needing clear sound that carries.
- Clean power and tuning control: Rockville DBM25 Class-AB amp delivers stable, Dyno-Certified RMS output-185W x2 @ 2Ω, 125W x2 @ 4Ω, or 370W x1 bridged-so music stays loud and clear at cruise. Conformal-coated PCB, silicone-sealed end panels, and rustproof aluminum heat sink enhance reliability. Adjustable HPF 60 Hz-1.2 kHz, LPF 50 Hz-250 Hz, 12dB bass EQ, and phase control let you dial clarity, punch, and staging.
- Smart mounting & aim: RWB90B reinforced nylon 360° swivel brackets let you aim forward to riders or back to the cockpit in seconds. Fits 1.26"-2.87" bars common on wake towers and many UTV/Jeep roll cages; longer 65/80 mm screws help with thicker tubing. Integrated grills protect drivers, while UV-treated materials keep the finish looking sharp. Secure clamp design maintains grip through chop, wakes, and trail vibration.
- Complete, corrosion-resistant install: RMWK4 4-AWG waterproof kit streamlines a reliable wiring job: tinned RCA interconnect, long power/ground runs with protective mesh, flat tinned speaker cable, remote wire, Mini-ANL holder with 120A/80A fuses, and terminals/ties. Marine-grade insulation and low-impedance cable preserve voltage and signal for stronger output and less hiss, letting DBM25 and RWB90B perform at their full potential.
