ATV300: How To Connect A Head Unit

Introduction

In this guide, we will show you how to set up your Rockville ATV300 amplifier to a head unit. We’ll cover the different input connections, including RCA and high-level outputs, and explain how to use the base remote knob for controlling the subwoofer level.

Step-by-Step Instructions

1. Connecting the RCA Inputs (If Your Head Unit Has RCA Outputs)

If your head unit has an RCA sub output, you can easily connect the ATV300 to it using RCA cables.

• Step 1: Take an RCA cable and plug one end into the sub output on your head unit.
• Step 2: Plug the other end of the RCA cable into the RCA inputs on the amplifier.

This connection will allow the amplifier to receive the audio signal directly from your head unit.

2. Using High-Level Outputs (If Your Head Unit Doesn’t Have RCA Outputs)

If your head unit does not have RCA outputs but has high-level outputs, you can use high-level to RCA adapters.

• Step 1: Take the wired end of the high-level adapter and connect it to the high-level output wires on your head unit.
• Step 2: Plug the other end of the adapter into the RCA input on the ATV300.

Alternatively, you can daisy chain these adapters off your vehicle's speakers to run the signal to the RCA input on your amplifier. Ensure that the signal runs from your vehicle's speakers to the adapter and then to the amplifier.

3. Connecting the Base Remote Knob

To control the level of the subwoofer from the front of your vehicle, you'll need to connect the base remote knob to your amplifier.

• Step 1: Take the base remote knob and the base remote wire.
• Step 2: Plug one end of the wire into the back of the base remote knob.
• Step 3: Plug the other end of the wire into the base remote input on the ATV300 amplifier.

Once connected, you can easily control the subwoofer level from the front of the vehicle.

4. Using High-Level Inputs (If No RCA Outputs on the Head Unit)

If your head unit does not have RCA outputs, you can use the high-level adapters as previously mentioned.

• Step 1: Connect the wires at the end of the high-level adapter to the positive and negative output wires on the back of your head unit.
• Step 2: Plug the other end into the RCA inputs of your amplifier.
• Step 3: Flip the input voltage switch on the top of the amplifier to the high setting.

This setup allows the amplifier to receive the audio signal via the speaker output from your head unit.

Conclusion

Setting up your Rockville ATV300 amplifier to your head unit is straightforward, whether you're using RCA outputs or high-level inputs. With the added flexibility of the base remote knob, you can control your subwoofer’s volume directly from the front of the vehicle.
