MB Quart GMR-RB4 4-Circuit Aftermarket Accessory Controller “Add-On” for use with the GMR7V1 Head Unit
Unlock the full potential of your GMR7V1 Source Unit with the MB Quart GMR-RB4 Relay Bank. This 4-channel accessory relay module allows you to control up to four 12V accessories directly from your GMR7V1’s digital switch interface—no need for separate switches or custom wiring. Simply plug the GMR-RB4 into the ‘AUX TRIGGER’ port using the provided JST connector for seamless integration. Designed for marine and powersports use, this relay bank features four fused 12V circuits (20A maximum per channel / 80A total maximum), making it ideal for powering lights, horns, compressors, and other accessories. The built-in LED fuse indicators make troubleshooting fast and easy—if a fuse blows, the corresponding LED stays lit to help you pinpoint the issue immediately. Installation is simple: connect the relay bank to your GMR7V1 (sold separately), run an 8 AWG 12V power and ground connection with an 80A fuse on the positive lead, and wire your 12V accessories to the output terminals.
