ATV220: How To Connect A Head Unit

Introduction

The Rockville ATV220 is a compact UTV and motorcycle Bluetooth amplifier that can also be connected to a head unit for improved control and sound quality. This guide will show you how to properly connect your head unit to the ATV220 using RCA cables and adjust the input voltage settings for optimal performance.

What You Need

• RCA cables (for audio connection)
• Head unit with RCA outputs (or a factory radio)
• Rockville ATV220 amplifier

Step-by-Step Instructions

Step 1: Locate the RCA Outputs on Your Head Unit

• On the back of your head unit or receiver, find the RCA output jacks (typically labeled "Front Out" or "Rear Out").

Step 2: Connect RCA Cables

1. Take one end of the RCA cables and plug them into the RCA outputs of your head unit.
2. Take the other end of the RCA cables and plug them into the RCA inputs on the ATV220 amplifier.

Step 3: Adjust the Input Voltage Switch

• The input voltage switch on the amplifier determines how sensitive the amp is to the input signal.
  • For an aftermarket head unit with RCA pre-outputs → Set the switch to "Low".
  • For a factory radio without RCA pre-outputs → Set the switch to "High" (you will need high-level speaker wire adapters for connection).

Conclusion

Setting up a head unit with the ATV220 amplifier is a quick and simple process. Just follow these steps: ✅ Connect RCA cables from the head unit to the amplifier.
✅ Set the correct input voltage based on your head unit type.
✅ Enjoy enhanced audio performance for your UTV, ATV, or motorcycle setup.
