💡 Control Multiple Accessories

Custom boats often include lighting and other electrical accessories beyond speakers and amplifiers.

The GMR-RB4 provides four relay channels for controlling compatible equipment.

Independent channels also provide greater flexibility when configuring a custom installation.

🎛️ Plug-and-Play Integration

Complicated accessory wiring can make upgrading a boat or powersports vehicle more difficult.

Professional installation remains recommended for power wiring, circuit protection, and accessory connections.

Proper fusing and wire sizing are important for reliable electrical performance.

🔊 Complete Your Entertainment System

The GMR-RB4 does not amplify speakers or subwoofers.

Instead, it handles accessory switching within compatible installations.

A complete system can include a multimedia receiver, marine speakers, amplifiers, lighting, and dedicated bass equipment.

For additional low-frequency options, explore our Car Subwoofers collection.

Dedicated bass equipment can provide deeper sound while full-range speakers handle vocals and instruments.

This combination creates a more complete entertainment experience during recreational activities.
