4 RWB70B 6.5" Marine Wakeboard Speakers + 4-Channel Amplifier + Amp Kit

This kit pairs four RWB70B 6.5" wakeboard tower speakers with a KRYPTON MF4 4-channel marine amplifier and a complete 4 AWG wiring kit, giving you everything you need to build a full tower audio system in one box. The RWB70B speakers deliver 150W RMS each through polypropylene mica-injected cones and 1" polyimide dome neodymium tweeters, producing clear highs and strong midrange that cuts through wind and engine noise on open water. Each speaker mounts with a 360-degree swivel nylon bracket reinforced with embedded steel, so you can angle sound exactly where you want it. The brackets fit bars from 1.26" to 2.87" and include both 65mm and 80mm stainless steel screws for thicker roll bars on boats, Jeeps, and ATVs.

The KRYPTON MF4 amplifier puts out 600W RMS across four channels with class A/B circuitry for clean, detailed sound at high volume. A conformal-coated PCB, aluminum heatsink, and stainless steel hardware make it fully marine rated. The onboard 12dB/octave crossover with low pass, high pass, bandpass, and subsonic modes lets you dial in each channel for your specific speaker setup. A built-in PA system with included microphone and talk-over function gives you communication capability on the water. The RMWK4 wiring kit rounds out the package with 4 AWG power and ground cables, tinned-OFC RCA cables, 16 AWG speaker wire, fuse holder, and all the terminals you need for a clean installation.
