ATV300: How To Set Up & Use

Introduction

In this guide, we will walk you through the setup process for the Rockville ATV300 amplifier, which includes connecting the amplifier to your subwoofer, head unit, and adjusting the sound controls. Additionally, we will cover the base remote knob and how to fine-tune your audio experience.

Step-by-Step Instructions

1. Powering the Amplifier

To start using your ATV300, you need to connect the following power wires:

• 12V Wire: Connect the 12V wire to the battery of your vehicle to power the amplifier.
• Remote Wire: Attach the remote wire to the ignition or accessory switch in your vehicle so the amplifier will turn on and off with your vehicle.
• Ground Wire: Secure the ground wire to the metal chassis of your vehicle to complete the power circuit.

Once these connections are made, your amplifier will power up and be ready to use.

2. Connecting the Subwoofer

To connect the subwoofer to the amplifier:

• White Wire (Positive): Connect the white wire to the positive terminal of the subwoofer.
• Black and White Wire (Negative): Attach the black and white wire to the negative terminal of the subwoofer.

Your subwoofer will now be connected and powered by the ATV300.

3. Connecting the Music Source (Head Unit)

There are two ways to connect your head unit to the ATV300:

Option 1: RCA Outputs

• Step 1: If your head unit has an RCA sub output, connect an RCA cable from that output to the RCA inputs on the amplifier.

Option 2: High-Level Outputs

If your head unit doesn’t have RCA outputs but has high-level outputs, you can use the included high-level to RCA adapters:

• Step 1: Connect the wired ends of the adapters to your head unit's high-level output wires.
• Step 2: Plug the other end into the RCA input on the amplifier.

You can also daisy chain the wires from your vehicle's speakers to the RCA input on the amplifier.

4. Connecting the Base Remote Knob

To control the subwoofer’s level, connect the base remote knob:

• Step 1: Plug one end of the base remote wire into the back of the base remote knob.
• Step 2: Plug the other end into the base remote input on the amplifier.

You can now adjust the subwoofer’s level from the front of your vehicle using the base remote knob.

5. Adjusting the Amplifier’s Sound Controls

Your ATV300 amplifier has several sound controls to help you fine-tune your setup:

• Phase Control: Adjust this knob from 0° to 180° to sync the subwoofer with the rest of your setup. If the subwoofer’s sound is out of phase (pushes in rather than out), adjust the phase accordingly.
• Bass Boost: Use this knob to add extra bass. You can set it from 0 to 12 dB, depending on your preference.
• Frequency and Subsonic Controls:
  • Frequency Knob: Set the low-end frequencies to be played by the subwoofer. For example, setting it to 50 Hz will play frequencies from 50 Hz and above.
  • Subsonic Knob: This controls the high-pass filter for the amplifier. Set it to 100 Hz to only hear frequencies below that threshold.

If you're using a ported subwoofer enclosure, set the subsonic filter to the subwoofer's tuning frequency. Refer to your subwoofer’s manual for this information.

• Level Knob: This adjusts the volume level of your subwoofer.
• Input Voltage Switch: Set this switch to high if you're using high-level adapters, or set it to low if you're using RCA outputs from your head unit.

6. Plate Removal for Accessing Controls

To access these settings, you need to remove the plate on top of the amplifier:

• Step 1: Use a Phillips head screwdriver to remove the screws holding the plate in place.
• Step 2: Use the plate removal tool to lift the plate off.

7. Testing the Setup

Once everything is connected, it’s time to test your setup:

• Play some music and start with the base remote knob at a lower setting.
• Gradually increase the volume and bass settings to your liking.
• Adjust the phase and frequency to match your subwoofer setup for the best sound experience.

Conclusion

With these simple steps, you can successfully set up your Rockville ATV300 amplifier for optimal performance in your vehicle. By adjusting the phase, bass boost, and subsonic filters, you'll be able to customize your sound and enjoy deep bass while keeping everything under control with the base remote knob.
