Step 2: Choose Your Connection Type
Decide whether you’ll use RCA or XLR connections. If your receiver or amplifier has XLR outputs, you may want to consider using XLR connections for a higher quality signal.
Step 3: Connect the First Subwoofer
Connect the first subwoofer to your receiver or amplifier using an RCA or XLR cable. Make sure to connect the cable to the correct output on the receiver or amplifier.
Step 4: Connect the Second Subwoofer
If your receiver or amplifier has multiple subwoofer outputs, connect the second subwoofer to the second output. If it has a single output, you’ll need to use a Y-splitter or a subwoofer amplifier with multiple outputs.
Step 5: Configure Your Receiver or Amplifier
Configure your receiver or amplifier to recognize the second subwoofer. This may involve setting the subwoofer output to “dual” or “stereo” mode. Consult your receiver or amplifier’s user manual for specific instructions.
Step 6: Calibrate Your System
Calibrate your system to optimize the performance of your two subwoofers. This may involve adjusting the subwoofer levels, crossover settings, and other parameters.
Tips and Tricks for Hooking Up Two Subwoofers
Here are some additional tips and tricks to keep in mind when hooking up two subwoofers:
Subwoofer Placement
Experiment with different subwoofer placements to find the optimal configuration for your room. Corner placement, near-field placement, and distributed placement are all viable options.

What are the benefits of having two subwoofers?
Having two subwoofers can significantly enhance the overall audio experience. Firstly, it provides a more immersive and engaging sound field, with a greater sense of bass presence and depth. This is because two subwoofers can produce a more even and consistent distribution of low-frequency energy throughout the room, reducing the likelihood of dead spots and hotspots.
Additionally, running two subwoofers can also increase the system’s overall power handling and reduce distortion. By dividing the low-frequency workload between two drivers, each subwoofer can operate within a more comfortable power range, resulting in a cleaner and more accurate bass response. This can be particularly beneficial in larger rooms or for music enthusiasts who crave extreme low-end extension.
Can I connect two subwoofers to a single amplifier or receiver?
Yes, it is possible to connect two subwoofers to a single amplifier or receiver, but there are some important considerations to keep in mind. Firstly, the amplifier or receiver must have enough power output to drive both subwoofers simultaneously. This means checking the amplifier’s power rating and ensuring it can handle the combined load of both subwoofers.
It’s also crucial to ensure that the subwoofers are properly wired and configured to work in tandem. This may involve using a “Y” adapter or a subwoofer splitter to connect the two subwoofers to a single output. Additionally, some subwoofers may have specific settings or configuration options for dual-subwoofer operation, so be sure to consult the user manual for guidance.
Do I need to calibrate my subwoofers when setting up a dual-subwoofer system?
Calibrating your subwoofers is essential when setting up a dual-subwoofer system. This involves adjusting the subwoofers’ level, crossover, and phase settings to ensure they’re working together in harmony. Calibration is critical because even small differences in settings can result in uneven or cancelling bass response.
To calibrate your subwoofers, you can use a calibration DVD or Blu-ray disc, or consult the user manual for specific guidance.
