Introduction
The Rockville RGHR-51 Marine Receiver features multiple power, speaker, and RCA connections to support a multi-zone audio setup, external amplifiers, subwoofers, and even video inputs and outputs. This guide will break down each wire, input, and output, helping you properly install and configure your receiver.
1. Power and Ignition Wiring
To power your receiver, connect the following wires:
| Wire Color | Function | Connection |
|---|---|---|
| Red (ACC Wire) | Accessory Power | Connect to the ignition of your boat so the receiver powers on with the boat. |
| Yellow (12V Wire) | Constant Power | Connect to the 12V power line of your house battery. |
| Black (Ground Wire) | Ground | Connect to the ground terminal of the house battery. |
| Blue (Remote Wire) | Amplifier Remote Turn-On | Connect to the remote terminal of an external amplifier so it powers on with the receiver. |
Important: Boats often have two 12V batteries in series (24V system), with one acting as the engine battery and the other as the house battery. All connections should go to the house battery.
2. Speaker Wiring for Zones 1 & 2 (High-Output Speaker Wires)
The RGHR-51 supports multi-zone audio, allowing different areas of the boat to have independent volume control.
Zone 1 Speaker Wiring
- White Wire = Left Channel
- Plain Wire = Positive (+)
- Black Stripe Wire = Negative (-)
- Gray Wire = Right Channel
- Plain Wire = Positive (+)
- Black Stripe Wire = Negative (-)
Zone 2 Speaker Wiring
- Green Wire = Left Channel
- Plain Wire = Positive (+)
- Black Stripe Wire = Negative (-)
- Purple Wire = Right Channel
- Plain Wire = Positive (+)
- Black Stripe Wire = Negative (-)
To connect speakers to zones 1 and 2, follow these steps:
- Take speaker wire and connect one end to the positive and negative wires of each zone.
- Connect the other end to the corresponding positive and negative terminals on the speakers.
3. RCA Outputs for Zones 3 & 4 (External Amplifier Support)
Zones 3 and 4 use RCA outputs, allowing you to add an external amplifier to power additional speakers.
- Connect RCA cables from the Zone 3 or Zone 4 outputs to an amplifier's RCA inputs.
- The amplifier can then power more speakers in additional areas of the boat.
4. Subwoofer Connection (Zone 5)
The receiver features a dedicated mono RCA output for a subwoofer, labeled Zone 5.
How to Connect a Subwoofer:
- Recommended Setup: Use an RCA Y-cable.
- Plug the single RCA end into the Zone 5 output.
- Plug the dual RCA ends into the subwoofer amplifier’s input or directly into an active subwoofer.
5. Auxiliary Inputs and Outputs
The RGHR-51 also supports AUX devices, USB storage, and video input/output.
AUX Input (Gray RCA - "AUX IN")
- Allows you to connect an MP3 player, phone, or external audio device.
- Use RCA cables or an RCA-to-AUX adapter.
USB Input
