RGHR45 4 Zone Marine Receiver w/Bluetooth+4) 6.5" Black Tower Speakers

This four-zone marine audio package pairs the RGHR45 Bluetooth gauge hole receiver with two pairs of RWB70B 6.5" black wakeboard tower speakers with 360-degree swivel brackets. The RGHR45 is built around independent volume control across four zones: zone 1 runs its built-in 28W x 4 RMS amplifier, zones 2 and 3 each control a pair of full-range RCA pre-amp outputs, and zone 4 is a dedicated subwoofer output. Volume for every zone can be adjusted from the receiver or the included wired remote. A 3" TFT color display makes navigation simple, and IP66 waterproof certification along with Humiseal-coated PCB boards protect the internals from spray and moisture.

The receiver streams music over Bluetooth to 50 feet and supports USB playback (including video), auxiliary input, a rear camera feed, and AM/FM radio. The RWB70B speakers handle 300W RMS per pair (150W each) at 96 dB sensitivity with a 70 Hz to 20,000 Hz response. Their 360-degree swivel nylon brackets reinforced with embedded steel fit bars from 1.26" to 2.87", with 65mm and 80mm screws for thicker tubing. Fully marinized polypropylene cones, stainless steel terminals, and rustproof hardware keep them performing in any water conditions. With four speakers driven directly from zone 1 and three pairs of RCA outputs for external amplifiers, this kit is ready to grow.
