(4) MTX WET65T Marine Wakeboard Speakers + 4-Ch. Amplifier + Bluetooth Receiver

This bundle builds a complete marine audio system around four MTX WET65T 6.5" tower speakers, a Rockville RGHR2 gauge-hole receiver, a Rockville RXM-S20 4-channel amplifier, and an RMWK4 waterproof wiring kit, so a boat goes from no sound system to a fully wired setup in one purchase. The WET65T speakers mount to the tower bar with all connections routed internally, carry an IP67 rating, and handle 75W RMS each for clear sound over wind and wake noise.

The RGHR2 receiver fits a standard gauge-hole opening and streams audio over Bluetooth from up to 50 feet away, plays music from a connected USB device or aux input, and picks up AM/FM radio with 30 total presets. A built-in 28W x 4 RMS amplifier gives the receiver its own power, and two sets of RCA preamp outputs, one front and one switchable rear/sub, let the RXM-S20 take over driving the tower speakers for real volume on the water. A 32.8-foot wired remote, included with the receiver, puts basic controls within reach anywhere on the boat.

The RXM-S20 amplifier is a water-resistant 4-channel design rated at 300W Dyno-Certified RMS (4 x 75W at 4 ohms), built on a double-sided PCB with a conformal coating for moisture protection. The RMWK4 kit ties the amplifier to the boat's electrical system with 4-gauge waterproof power and ground cable, tinned-OFC RCAs, and mini-ANL fuses rated at 120A and 80A, so the whole system installs with marine-grade parts throughout instead of mixing in cables not rated for the environment.
