In this article, we’ll explore the intricacies of connecting two subwoofers, the benefits of doing so, and practical tips to help you achieve a powerful audio setup that will make you feel like you’re right in the action.
The Advantages of Connecting Two Subwoofers
Before diving into the “how,” let’s take a moment to discuss why you might want to connect two subwoofers. Here are some compelling reasons:
1. Enhanced Sound Quality: By connecting two subwoofers, you can achieve a more balanced sound. Two subwoofers can smooth out the bass response in a room, reducing peaks and nulls in the bass frequencies that can occur with a single subwoofer. This results in a more even distribution of sound throughout the listening area.
2. Increased Output and Power: Connecting two subwoofers allows you to deliver twice the energy, leading to a more powerful and impactful listening experience. Whether you’re watching an action movie or listening to your favorite tracks, the added bass can heighten the excitement and immersion.
3. Flexibility in Placement: Having two subwoofers provides more flexibility in placement around your room. This allows you to experiment with different positions to find the sweet spot that delivers the most balanced bass sound.
Types of Connections: How to Connect Two Subwoofers
Now that we understand the benefits, let’s explore the methods of connecting two subwoofers. The two most common ways are through a parallel connection and a series connection.
Parallel Connection
In a parallel connection, both subwoofers are connected directly to the amplifier’s output. This method is often preferred because it allows both subwoofers to receive identical signals from the amplifier.
Step-by-Step Process to Connect in Parallel:
-
Check Your Amplifier’s Specifications: Ensure that your amplifier can handle the total load of both subwoofers. If you connect two subwoofers with the same impedance, the total impedance will halve. For example, if both subwoofers are 8 ohms, the total impedance when connected in parallel would be 4 ohms.
-
Use the Right Cables: You will need high-quality speaker wire to connect both subwoofers. Ensure that the wire gauge is adequate for the distance and power you plan to run through.
-
Connect the Wires: Connect the positive terminal on the first subwoofer to the positive terminal of the amplifier, and do the same for the negative terminals. Repeat this for the second subwoofer, ensuring that both subwoofers are connected to the same terminals (positive to positive and negative to negative).
Series Connection
In a series connection, you connect one subwoofer to the amplifier and then connect the second subwoofer to the first. This configuration increases the overall impedance of the system.
Step-by-Step Process to Connect in Series:
-
Understand Impedance Changes: When connecting subwoofers in series, you add the impedance values together. So, if both subwoofers are 8 ohms, the total impedance presented to the amplifier will be 16 ohms.
-
Use Proper Wiring: You’ll need speaker wire similar to that used in parallel connections.
-
Connect the Wires: Connect the positive terminal of the amplifier to the positive terminal of the first subwoofer. Then, connect the negative terminal of the first subwoofer to the positive terminal of the second subwoofer. Finally, connect the negative terminal of the second subwoofer to the negative terminal of the amplifier.
Optimal Placement of Subwoofers
After connecting your subwoofers, you may wonder about the best placement within your room. Here are some factors to consider for optimal bass performance:
Room Acoustics
The acoustics of your room will significantly affect the performance of your subwoofers. Hard surfaces like tiles and glass can cause echo, while soft surfaces can absorb sound. Try to experiment with different placements to see what provides the best sound quality across the listening area.
The “Subwoofer Crawl” Technique
To find the ideal placement for your subwoofers, consider using the “subwoofer crawl” technique. Here’s how it works:
- Place one subwoofer in your primary listening position.
- Play a bass-heavy track and move around the room, paying attention to where the bass sounds the best.
- Mark the spots that seem to boost bass performance. Move your subwoofer to one of these spots and repeat the process with the second subwoofer.
Symmetrical Placement
For balanced sound, aim to place the subwoofers symmetrically within the room. Avoid placing one subwoofer in a corner and the other towards the center, as this can lead to uneven bass output.
Managing Phase and Frequency Settings
Once you have your subwoofers connected and positioned correctly, you’ll want to ensure that they are tuned properly to work together harmoniously.
Understanding Phase
Phase adjustment is crucial when using multiple subwoofers. Ideally, both subwoofers should be working in sync to create a cohesive sound. Most amplifiers and subwoofers feature a phase switch (0° or 180°) or a variable phase knob. Testing both settings can help you find the option that delivers the smoothest bass response in your room.
Tuning Frequency Settings
Adjust the crossover frequency for each subwoofer to blend seamlessly with your main speakers. The crossover frequency determines which frequencies are sent to the subwoofer versus the main speakers.
Typically, a crossover frequency between 80Hz and 120Hz is effective for most setups. However, this can vary based on your room’s acoustics and the specifications of your speakers.
Common Challenges When Connecting Two Subwoofers
While connecting two subwoofers offers many benefits, it can also present some challenges. Being aware of these issues can help you troubleshoot problems effectively:
Impedance Mismatches
One of the most common challenges is impedance mismatch. If your amplifier is not rated for the new combined load, it could lead to distortion or even damage the amplifier. Always check the specifications before proceeding.
Interference and Noise
Sometimes, connecting multiple subwoofers can introduce unwanted interference or noise, particularly if the grounding is not done correctly. Ensure that all connections are secure and consider using an audio isolator if you experience buzzing or humming noises.
Conclusion: The Power of Two
Connecting two subwoofers can significantly enhance your audio experience, whether for home theater setups, music listening, or gaming. By understanding the different connection methods, placement strategies, and tuning options, you can create a soundscape that not only fills the room but elevates every sound you hear.

How can I connect two subwoofers to my audio system?
There are several methods to connect two subwoofers, depending on your audio system configuration. If your receiver has multiple subwoofer outputs, you can simply connect each subwoofer directly to these outputs using RCA cables. This method allows you to control both subwoofers independently and is generally the simplest approach for most home audio systems.
If your receiver has only one subwoofer output, you can use a Y-splitter cable to split the signal. Another option is to connect one subwoofer to the line-in of the second subwoofer, provided the second unit has a line-out. This way, the first subwoofer will send the signal to the second, creating an integrated system. Regardless of the method, remember to adjust the gain, phase, and crossover settings for optimal sound performance.
Do I need a subwoofer amplifier for dual setups?
Whether or not you need a subwoofer amplifier for dual setups depends largely on the type of subwoofers you are using. Active subwoofers come with built-in amplifiers, and if you choose to use two active subwoofers, there’s no need for an external amplifier. Simply connect them to your audio receiver, and they’ll handle the power requirements themselves.
However, if you are using passive subwoofers, you will need a dedicated amplifier to power both units adequately. In this case, make sure the amplifier can accommodate the combined power handling of both subwoofers. Correct amplification is crucial to ensure that both subwoofers perform optimally and deliver a balanced, rich audio experience.
What settings should I adjust for optimal performance?
When connecting two subwoofers, it’s important to adjust several settings for optimal performance.
