Introduction

The Rockville RGHR-51 Marine Receiver features a multi-zone audio system, allowing you to set up independent speaker zones around your boat or vessel.

1. Understanding the Zone Outputs

The RGHR-51 supports up to five audio zones:

2. Connecting Speakers to Zones 1 & 2

Zones 1 and 2 use high-output speaker wires from the wire harness, allowing you to connect speakers directly.

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 (-)

How to Connect Speakers

1. Use speaker wire to connect the positive and negative wires of each zone.
2. Attach the other end of the wire to the positive and negative terminals on your speakers.
3. Repeat this process for all speakers in Zones 1 and 2.

3. Connecting External Amplifiers for Zones 3 & 4

Zones 3 and 4 are designed for external amplifiers, allowing you to expand your speaker setup.

How to Connect an Amplifier
