Rockville RWB90W Bundle: (4) 8-in 300W Peak / 200W RMS White Wakeboard 360° Swivel Tower Speaker, RGHR51 Single-Din 5-Zone Marine Receiver, Bluetooth, USB, AM/FM, Wired Remote, 5-Items

This Rockville marine bundle teams the RGHR51 single-din 5-zone receiver with two pairs of RWB90W 8" swivel wakeboard speakers to deliver controlled, full-range sound across your boat or powersports build. The RGHR51 mounts in a standard single-din opening (1.97" x 3.94" cutout, 3.23" depth) and uses a built-in TDA7850 amplifier rated at 4 x 72 watts peak / 4 x 28 watts RMS to power two onboard zones directly, while three additional RCA pre-amp zones allow external amplifiers to drive cabins, towers, or subwoofers with independent volume control from the head unit or the included wired remote.A 4" TFT color display and large front-panel buttons make operation straightforward, even in bright conditions. Bluetooth streaming, USB playback and charging (5V/500 mA, supports up to 16GB drives), RCA A/V and AUX inputs, and an AM/FM tuner with 18 FM / 12 AM presets give you flexible source options. The rear-camera input can be tied to a reverse or docking camera for added convenience at the marina.Built for marine environments, RGHR51 carries an IP66 rating, uses a Humiseal-coated PCB, and is tested to ASTM B117 and D4329 standards for resistance to salt spray and UV exposure.The included RWB90W 8" wakeboard speakers provide the main output at the tower or roll bar. Each 4-ohm enclosure uses a polypropylene mica-injected cone with Santoprene surround, 1" polymide dome neodymium tweeter, built-in two-way crossover, and Y30 magnet motor structure for a 60-20,000 Hz response and 98 dB sensitivity. Power handling is rated at 200 watts RMS / 300 watts peak per speaker (400 watts RMS / 600 watts peak per pair). Fully marinized construction with sealed terminals and stainless mounting hardware, plus UV-coated nylon brackets reinforced with embedded steel, support 360° rotation and fit common tower and roll-bar diameters from approximately 1.26" to 2.87" with a 10.5" mounting depth.
