RVA-M3 V1 | V2: Controls, Inputs, Outputs Explained

Introduction

The Rockville RVA-M3 V2 is a high-performance car amplifier designed to power subwoofers efficiently. This guide will walk you through the controls, inputs, and outputs of the amplifier.

Note: If you own the RVA-M3V1, the setup is identical since the only changes in the V2 model are internal enhancements.

Power Terminals & Wiring

To power your amplifier, connect the power terminals to your vehicle's electrical system:

• 12V+ Terminal → Connects to the positive terminal of your car battery.
• Remote Terminal → Connects to the ignition wire (turns the amp on/off with your car).
• Ground Terminal → Connects to a metal chassis ground for a solid electrical connection.

Fuses & Protection

• The amplifier includes built-in fuses to protect against electrical issues.
• Extra fuses are included in case replacements are needed.
• Power & Protect Lights:
  • Power Light: Illuminates when the amp is functioning correctly.
  • Protect Light: If this turns on, the amp requires adjustments to prevent overheating or electrical issues.

Speaker & Subwoofer Wiring

The RVA-M3 V2 is a 1-ohm stable amplifier, making it compatible with various subwoofer setups:

• Single 1-ohm subwoofer → Connect one positive and one negative terminal from the amp to the sub.
• Two 2-ohm single voice coil (SVC) subwoofers in parallel → Use both positive and both negative terminals on the amp to wire both subs, matching the 1-ohm impedance.

⚠️ Important: The maximum power should not exceed 1,000 watts RMS.

Inputs & Outputs

RCA Connections

• RCA Inputs → Connects to your head unit (car stereo) via the subwoofer RCA outputs.
• RCA Bridge Mode:
  • Used to link two RVA-M3 V2 amplifiers together for increased power.
  • Connect "RCA Bridge Out" on Amp 1 → to "RCA Bridge In" on Amp 2.

Tuning the Amplifier Settings

Gain Control

• Adjusts the input level to match your head unit’s preamp output.
• Tip: Follow Rockville’s gain-setting guide for optimal performance.

Bass Boost

• Adds extra low-end frequencies.
• Adjustable from 0dB to +12dB (use cautiously to prevent distortion).

Low-Pass & High-Pass Filters

• Low-Pass Filter (LPF) → Sets the upper limit of frequencies the subwoofer plays.
  • Example: Set to 150Hz → The sub plays everything below 150Hz.
• Subsonic High-Pass Filter → Filters out unnecessary low frequencies.
  • Example: Set to 30Hz → The sub plays everything above 30Hz.

For Ported Sub Enclosures:

• Tune the high-pass filter to the enclosure’s tuning frequency (check manufacturer specs).

Additional Features

Phase Control

• Adjusts phase alignment to ensure proper bass response.
• If the bass sounds weak or out of sync, use this knob to correct it.

Bass Remote Knob

• Connects via the remote wire to the amp.
• Allows real-time bass control from the driver’s seat.
• Includes a Clipping LED to prevent excessive distortion.

Troubleshooting & FAQs

Q: Why is my amp going into protect mode?

✔ Check for loose connections, overheating, or impedance mismatches.

Q: Why is my bass weak?

✔ Adjust the gain, low-pass filter, and bass boost settings.

Q: Can I connect a factory head unit?

✔ Yes, but you may need a line output converter (LOC) for RCA outputs.

Conclusion

The Rockville RVA-M3 V2 offers powerful performance and flexible setup options. By following this guide, you can correctly wire, tune, and optimize your amplifier for maximum bass output.
