RGHR2 + RWB80B + RXM-T1 + RMWK4

This amplified wakeboard audio system combines the RGHR2 Bluetooth gauge hole receiver, one pair of RWB90B 8" black wakeboard tower speakers with 360-degree swivel brackets, the RXM-T1 two-channel marine amplifier with 370W Dyno-Certified RMS, and the RMWK4 amplifier wiring kit. It pairs 8" drivers with a dedicated amp so you get the bass depth and volume needed to fill open water at speed. The RGHR2 handles Bluetooth streaming to 50 feet, USB, auxiliary, and AM/FM inputs, with IP66 waterproofing and a wired remote on 32.8 feet of cable.

The RXM-T1 amplifier runs a class A/B circuit with class G rail-switching technology, achieving about 65 to 70 percent efficiency while keeping the clean sound quality that class A/B is known for. It delivers 125W x 2 at 4 ohms and can bridge to 370W on a single channel. Conformal-coated marine PCB, stainless steel hardware, and a 50A maxi fuse back up the protection. The RWB90B speakers handle 200W RMS each with high sensitivity and 360-degree swivel nylon brackets reinforced with embedded steel. These fit tower tubing, roll bars, and ATV cages with stainless mounting hardware included. The RMWK4 kit provides 4-gauge power and ground cables, a 20-foot OFC RCA cable, speaker wire, fuses, and all terminals for a clean run from battery to tower.
