Choosing the Right Configuration
There are a few different ways to connect two subwoofers to one amplifier, including series and parallel configurations. Understanding these configurations will help you decide the best setup for your audio system.
Series Configuration
In a series configuration, you connect the positive terminal of one subwoofer to the negative terminal of the other. This method adds up the impedance of both subwoofers.
Advantages of Series Configuration
- Allows you to increase the overall impedance, which is useful if your amplifier has a minimum impedance rating that you need to adhere to.
Disadvantages of Series Configuration
- Reduces the power sent to each subwoofer; thus, it may not produce the desired volume and effect of dual subwoofers.
Parallel Configuration
In a parallel configuration, you connect the positive terminal of both subwoofers to the positive terminal on the amplifier, and the same goes for the negative terminals. This configuration lowers the overall impedance.
Advantages of Parallel Configuration
- Increases the power sent to both subwoofers, which can result in a greater sound output and more bass presence.
Disadvantages of Parallel Configuration
- Risks overloading your amplifier if the combined impedance is below its rated capacity.
Calculating Impedance
Knowing the impedance ratings of your subwoofers is crucial for deciding your connection type and ensuring safe operation.
Single Voice Coil (SVC) Subwoofers
For SVC subwoofers, the impedance is straightforward. If you have two 4 ohm SVC subwoofers:
- Series Connection: 4Ω + 4Ω = 8Ω
- Parallel Connection: 1/(1/4 + 1/4) = 2Ω
Dual Voice Coil (DVC) Subwoofers
DVC subwoofers offer more flexibility. Each coil can be wired independently. For example, if you have two 2 ohm DVC subwoofers, you can wire them in various configurations:
- Series Connection: 2Ω + 2Ω = 4Ω
- Parallel Connection: 1/(1/2 + 1/2) = 1Ω
Connection Process: Step-by-Step
Now that you’ve chosen your configuration and calculated your impedance, it’s time to get hands-on. Follow these steps to connect your two subwoofers to one amplifier.

Begin by gathering all your tools and materials in one place. Make sure everything is accessible to streamline the process.
Step 2: Disconnect Power
Before you start connecting anything, ensure that the amplifier is disconnected from the power source to avoid any risk of electric shock or damage to your components.
Step 3: Connect the Subwoofers
For Series Connection: Connect the positive terminal of the amplifier to the positive terminal of Subwoofer 1. Then, connect the negative terminal of Subwoofer 1 to the positive terminal of Subwoofer 2. Finally, connect the negative terminal of Subwoofer 2 to the amplifier’s negative terminal.
For Parallel Connection: Connect the positive terminal of the amplifier to the positive terminals of both Subwoofer 1 and Subwoofer 2. Then, do the same for the negative terminals.
Step 4: Secure Connections
Use connectors or solder the connections to ensure they are secure. Loose connections can lead to poor sound quality and potential damage.
Step 5: Check Impedance
Verify that the total impedance fall within the recommended range for your amplifier. This step is crucial to prevent overloading your amplifier and damaging your equipment.
Step 6: Connect the Amplifier
After confirming all wiring connections, reconnect your amplifier to the power source.
Step 7: Sound Test
Play some music or a sound test that emphasizes low frequencies. Listen for any distortion or imbalance in sound. Adjust the amplifier gain as needed to ensure optimal performance.

What do I need to connect 2 subs to one amp?
To connect two subs to one amplifier, you will need a compatible amplifier with enough power handling to accommodate both subs. It is also important that the amplifier has the appropriate number of outputs, or you may require a Y-splitter or speaker wire to combine the connections. Additionally, ensure that the subs are rated for the impedance that the amplifier can handle.
You will also need speaker wire, connectors, and may want to consider terminal cups for a professional finish. It is important to check the specifications of the subs and the amp to ensure compatibility, including power handling and impedance ratings, to avoid damage to any components.
Can I connect different brand subs to the same amp?
Yes, you can connect different brand subs to the same amplifier, as long as both subs have compatible impedance ratings and power handling capabilities. It’s crucial to ensure that the amplifier can handle the combined load of both subs without exceeding its maximum output or impedance ratings.
However, it’s worth noting that using different brands may lead to varying tonal qualities and performance characteristics. The result could be a less-than-ideal listening experience, so if possible, try to match the subs in terms of size, power handling, and frequency response for the best results.
How do I wire two subs in parallel?
To wire two subs in parallel, start by connecting the positive terminal of the first sub to the positive terminal of the amplifier. Next, connect the negative terminal of the first sub to the positive terminal of the second sub, and then connect the negative terminal of the second sub to the negative terminal of the amplifier. This creates a parallel circuit that allows both subs to receive the same voltage.
Keep in mind that wiring in parallel will lower the total impedance, which can increase the power output from the amplifier. Make sure the amp can handle the resulting impedance; otherwise, you risk damaging the amplifier or the subs. Additionally, good quality speaker wire should be used to ensure a secure and effective connection.
How do I wire two subs in series?
To wire two subs in series, begin by connecting the positive terminal of the first sub to the positive terminal of the amplifier. Then, connect the negative terminal of the first sub to the positive terminal of the second sub. Finally, connect the negative terminal of the second sub to the negative terminal of the amplifier. This wiring configuration allows the total impedance to increase, leading to different power handling characteristics.
Wiring subs in series can be advantageous if your amplifier can’t handle very low impedances. It’s important to ensure that both subs have the same impedance rating to maintain appropriate power distribution. If the subs have different impedance ratings, it can result in poor performance or potential damage to the components.
What are the benefits of connecting two subs to one amp?
Connecting two subs to one amplifier can enhance the overall sound quality and bass response in your audio system. By having two subs working together, you can achieve a more even distribution of sound and improved low-frequency performance. This can lead to a richer, fuller listening experience, particularly in larger spaces where a single sub may struggle to fill the area with sound.
Additionally, using two subs can help with system efficiency. With both subs connected, the workload is shared, which can reduce distortion and allow each sub to operate within its optimal range. This setup can ultimately provide a more powerful output without requiring a larger or more expensive amplifier.
What should I consider regarding impedance when connecting two subs to one amp?
When connecting two subs to one amplifier, impedance is a critical factor to consider. The total impedance that the amplifier sees will influence the power distribution and overall performance. It’s important to match the combined impedance of your subs to what the amplifier is rated for. If the total impedance is lower than what the amp can handle, there is a risk of overheating or damaging the amplifier.
To calculate the total impedance, use the formula suitable for the configuration you’re using—whether series or parallel. For parallel connections, the formula for total impedance is 1/(1/R1 + 1/R2) while for series, it’s simply the sum R1 + R2. Understanding these calculations will ensure that your setup remains safe and efficient.
Can I use an amplifier not specifically designed for subs?
While you can use an amplifier that is not specifically designed for subwoofers, it may not provide the best performance for your subs. Standard amplifiers may lack the power handling or low-frequency response needed for optimal bass reproduction. If the amplifier does not have specific low-pass filtering capabilities, it might not adequately filter out higher frequencies that you generally don’t want in a sub’s output.
If using a standard amplifier, ensure it has a suitable power output and is compatible with the subs’ impedance requirements. For true subwoofer performance, a dedicated subwoofer amplifier is often recommended, as it typically provides better optimization for low-frequency playback and overall sound clarity while being designed for stability under heavy load.
What are some common issues when connecting two subs to one amp?
Some common issues when connecting two subs to one amplifier include mismatched impedance, which can lead to power handling problems, and differences in subwoofer characteristics that affect sound quality. If one sub is significantly more efficient than the other, it may overpower the weaker sub, resulting in distortion or damage. It’s important to ensure that both subs are similar in terms of power handling and performance specifications.
Another frequent issue is poor wiring or connections, which can cause signal loss or inconsistent bass output. Make sure to use high-quality speaker wire and secure all connections to avoid problems. Additionally, inadequate amplifier power can lead to clipping, which adversely affects the overall sound quality. Always check that your amplifier can support the total load once both subs are connected.
