RGHR2 + MS525B 2-Pack

This hot tub audio package pairs the RGHR2 Bluetooth gauge hole receiver with one pair of MS525B 5.25" black waterproof marine speakers. It gives you a self-contained music system that fits the compact spaces around a hot tub, spa, or outdoor entertainment area. The RGHR2 receiver installs in any standard tachometer-size opening and puts out 28W x 4 RMS through its built-in amplifier. Bluetooth streaming reaches up to 50 feet so you can play music from your phone while soaking. USB, auxiliary, and AM/FM inputs round out the source options, and IP66 waterproof certification keeps the unit protected from steam, splashing, and moisture. The included wired remote on 32.8 feet of cable means you do not have to get out of the water to change tracks.

The MS525B speakers deliver 200W RMS per pair with a frequency response of 110 Hz to 20 kHz and IP56 waterproof certification. Injection-molded polypropylene cones, cloth surrounds, and anti-UV ABS plastic baskets with grills hold up against humidity, chlorine, and direct sunlight. A 5.31" cutout diameter and 1.85" mounting depth make them easy to flush-mount in a hot tub cabinet, deck panel, or outdoor wall. Pre-installed stainless steel mounting screws and a cutting template simplify the installation.
