ATV420: How To Connect A Head Unit

Introduction

The Rockville ATV420 is a 4-channel Bluetooth amplifier designed for ATVs, UTVs, and motorcycles. It can be connected to a head unit (receiver) for enhanced audio control. This guide will walk you through how to connect a head unit to your ATV420 amplifier using RCA cables.

What You’ll Need

• Rockville ATV420 Amplifier
• Head unit (receiver) with RCA outputs
• Two RCA cables
• Wire strippers (if needed)
• Included high-level input adapters (if using a stock radio)

Step 1: Check Your Head Unit’s RCA Outputs

Before starting, determine how many RCA outputs your receiver has:

1. Two RCA Outputs (Front & Rear):
   • You can use all four channels on the amplifier.
   • Set the amplifier to 4-channel input mode.
2. One RCA Output (Single Set):
   • You will only use channels 1 and 2 on the amplifier.
   • Set the amplifier to 2-channel input mode so that all speakers play the same audio.

Step 2: Connecting the RCA Cables

1. Take one end of each RCA cable and plug them into the RCA outputs of your head unit.
2. Take the other ends and plug them into the RCA inputs on the amplifier:
   • Use Channels 1 & 2 and Channels 3 & 4 for 4-channel mode.
   • Only use Channels 1 & 2 for 2-channel mode.

Step 3: Adjusting the Input Voltage Switch

• The input voltage switch allows you to set the sensitivity to match your head unit.
• If using an aftermarket head unit (with RCA pre-outs):
  • Set the input voltage switch to LOW.
• If using a factory or stock radio:
  • Set the input voltage switch to HIGH.
  • Use the included high-level adapters to connect the speaker outputs of your radio to the amplifier.

Step 4: Testing the Setup

1. Power on your head unit and amplifier.
2. Play music and test the speakers.
3. Adjust the volume and balance settings on your head unit.
4. Confirm that all speakers are working properly.

Conclusion

Connecting a head unit to your Rockville ATV420 amplifier is simple and provides better audio control. Just match your RCA outputs to the correct input mode, set the input voltage correctly, and enjoy high-quality sound on your ATV, UTV, or motorcycle.

Use 4-channel mode for full RCA output, 2-channel mode for single RCA output
Set input voltage to LOW for aftermarket head units, HIGH for factory radios
Use high-level adapters for stock radios without RCA outputs
Test your setup to ensure all channels are working correctly
