Step-by-Step Guide: Setting Up a Powered Subwoofer with Pre

For audiophiles and movie enthusiasts, a powered subwoofer with pre is a game-changer. It enhances your sound system, delivering deep, rich bass that elevates your listening experience. However, setting up a powered subwoofer with pre can be a daunting task, especially for beginners. This guide aims to simplify the process, walking you through each step to ensure a successful setup.

Understanding Pre-Out and Sub-Out

Before diving into the setup process, it’s crucial to understand what a pre-out and sub-out are. A pre-out, short for preamplification output, is a connection on your receiver or amplifier that sends an audio signal to an external device, such as a subwoofer. A sub-out, on the other hand, is a specific pre-out designed to connect to a subwoofer. It filters out high frequencies, transmitting only the bass frequencies.

Step-by-Step Guide to Setting Up a Powered Subwoofer with Pre

Step 1: Gather Your Equipment

Before you begin, ensure you have all the necessary equipment:

  • Powered Subwoofer with Pre
  • RCA Cables
  • Speaker Wire
  • Receiver or Amplifier

Step 2: Locate the Sub-Out on Your Receiver or Amplifier

The sub-out connection is typically found on the back of your receiver or amplifier. It should be labeled as such.

Step 3: Connect RCA Cables

Connect one end of the RCA cables to the sub-out on your receiver or amplifier and the other end to the input on your powered subwoofer with pre.

Step 4: Connect Speaker Wire

Connect the speaker wire from your receiver or amplifier to the speaker-level inputs on your powered subwoofer with pre. This connection allows the subwoofer to receive the audio signal from your receiver or amplifier.

Step 5: Turn On Your System

After all connections have been made, turn on your receiver or amplifier and your powered subwoofer with pre. Ensure that your receiver or amplifier is set to “Subwoofer On” mode.

Step 6: Adjust Settings

Adjust the volume on your subwoofer to a comfortable level. You can also adjust the crossover frequency to ensure that your subwoofer is only playing the lower frequencies and not interfering with your other speakers.


Setting up a powered subwoofer with pre may seem complex at first, but with this guide, it becomes a straightforward process. By following these steps, you can enjoy your music and movies to the fullest, experiencing deep, rich bass that takes your listening experience to the next level.
