RVA-M3 V2: How To Set Up

Introduction

The Rockville RVA-M3 V2 is a powerful car amplifier designed for subwoofer setups. This guide will walk you through installation, wiring, tuning, and operation. If you own the RVA-M3V1, you can follow the same steps as the V2 update only involves internal improvements.

What's Included

✔ RVA-M3 V2 Amplifier
✔ Bass Remote Knob & Remote Wire
✔ Extra Fuses
✔ Mounting Hardware

Step-by-Step Installation

1. Powering the Amplifier

To power the amplifier, connect the following 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 to turn the amp on/off with your car.
• Ground Terminal → Connects to a metal chassis ground for a secure connection.

If you need a wiring diagram, refer to Rockville’s amplifier wiring guides.

2. Speaker/Subwoofer Wiring

The RVA-M3 V2 is a 1-ohm stable amplifier, which means it supports various subwoofer configurations:

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

⚠️ Important: Ensure the total power doesn’t exceed 1,000W RMS.

3. RCA & Head Unit Connection

To connect the head unit (car stereo):

• Find the RCA "Sub Out" on your head unit (or use standard RCA outputs).
• Plug one end of the RCA cable into the head unit’s subwoofer output.
• Plug the other end into the RCA Input on the amplifier.
• Set gain and frequency range (explained below).

Tuning the Amplifier Settings

1. Gain Control

• Adjust the gain according to your head unit’s preamp output.
• Follow Rockville’s gain-setting guide for best results.

2. Bass Boost

• Increases low-end frequencies.
• Adjustable from 0dB to +12dB (use sparingly to prevent distortion).

3. Low-Pass & High-Pass Filters

These control the frequency range sent to your subwoofer:

• Low-Pass Filter (LPF) → Sets the upper limit of frequencies your subwoofer plays.
  • Example: Setting it to 150Hz means it plays everything below 150Hz.
• Subsonic High-Pass Filter → Eliminates unwanted low frequencies.
  • Example: Setting it to 30Hz means it plays everything above 30Hz.

For Ported Sub Enclosures → Set the high-pass filter to your enclosure’s tuning frequency (check the subwoofer manual).

Additional Features

1. Phase Control

• Adjust this if the subwoofer sounds out of sync with your car’s audio.
• Helps align bass waves with the rest of your system.

2. Bass Remote Knob

• Connects to the amp using the included remote wire.
• Allows real-time bass control from your driver’s seat.
• Includes a clipping LED indicator to prevent distortion.

3. RCA Bridge Mode

• Allows linking of two RVA-M3 V2 amplifiers for even higher power output.
• Use the RCA "Bridge Out" from Amp 1 → Connect to RCA "Bridge In" on Amp 2.

Demo & Performance

Once set up, play music to test the amplifier. The RVA-M3 V2 delivers powerful bass, and with the remote knob, you can fine-tune it on the go.

Troubleshooting & FAQs

Q: Why is the amp going into protect mode?

✔ Check for loose connections or incorrect impedance matching.

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

Setting up the Rockville RVA-M3 V2 is easy and customizable for different subwoofer configurations. Follow these steps to wire, tune, and optimize your amplifier for deep, clear bass.
