(4) RWB70B 6.5" Marine Wakeboard Swivel Speakers + Amp + Receiver + Wiring Kit

This is the complete package: four RWB70B 6.5" black wakeboard tower speakers, a DBM45 4-channel marine amplifier, an RGHR2 gauge-hole Bluetooth receiver, and an RMWK4 4 AWG wiring kit. From source to speaker, nothing else is required. The RGHR2 receiver fits a standard gauge-hole opening and streams music over Bluetooth from up to 50 feet away, plays USB audio, and picks up AM/FM radio with 18 FM and 12 AM presets. Its built-in 28W x 4 RMS amplifier can drive the speakers directly for casual listening, while two sets of RCA preamp outputs feed the DBM45 when you want real volume.

The DBM45 puts out 500W Dyno-certified RMS across four channels, and its conformal-coated PCB and silicone terminal covers keep moisture out of the electronics. A fully adjustable crossover with subsonic filtering lets you shape the sound per channel. Each RWB70B speaker handles 150W RMS through a polypropylene mica-injected cone and 1" neodymium tweeter, and the 360-degree swivel brackets mount to bars from 1.26" to 2.87". An included wired remote for the RGHR2 with a 32.8 foot cable means you can control volume and track selection from anywhere on the boat.
