There may not be a default output for your subwoofer to connect to the speaker on some vintage receivers. When connecting your speakers to a subwoofer, you must adjust the cabling and choose a different angle.

The subwoofer and speakers often send and receive audio signals at the same time. All of the equipment interprets the signal simultaneously. What then, when the sound is generated from several angles? How are speakers connected to a subwoofer? or if there isn’t an output connection for your subwoofer?

Buckle up because it’s going to be a fantastic one as we explore these ideas and more!

What Are My Subwoofer’s Speaker Level Outputs?

There are two channels on speaker-level outputs: right and left. They also often use speaker inputs. The speaker wires are routed into the sub and then to the speakers, not into a subwoofer output on the audio receiver.

Your primary speakers are connected to the subwoofer through the outputs. Have a look at this video to learn more about the speaker.

An effective technique to connect a powered speaker to a mixer is through this output option. The “through” connection is another name for the output.

Just How Do Speaker Level Outputs Operate?

How To Connect A Subwoofer To Speaker Level Outputs?

They generate sound using the speaker’s cone’s vibrations. The sound is released into your ear canal when the vibrations strike your eardrum after traveling through the air. That is the simplest explanation for how a speaker produces sound, but how does everything actually operate internally?

There is a high impedance electrical connection within subwoofers with speaker line inputs. The signal is captured by this circuit. It could be a low pass or high pass filter that lets through each signal at its lowest frequency. The frequency must be above a specific threshold if it is a high filter and below a specific threshold if it is a low filter. The crossover blocks any unwanted frequencies that exceed a particular amount at the cutoff frequency (the crossover frequency). Because they are sent to the speakers, these frequencies must be of a high quality. Make sure your subwoofer crossover is correctly configured.

Low pass filters occasionally snuck into the subwoofer signals balance your bass and ensure that you can hear the song properly.

The frequency that the subwoofer speaker line out uses to drive the associated speakers is then provided by the filter to the subwoofer amp or amps. These signals must, of course, be separated! Some subs have a low pass filter that passes frequencies to the sub and a high pass filter that passes higher frequencies to the main speakers.

Speaker connection for a subwoofer

The questions and responses listed below can help with any confusion.

Speaker-level Input: What Is It?

They serve as the connection between your amplifier and speaker. If your radio does not offer low-level inputs, you can attach an amplifier to it using your speaker-level inputs.

How Do I Make My Subwoofer Produce More Bass?

OFFSET your system. Bass boost is disabled when the low-pass filter is turned up all the way. Reduce the gain of your subwoofer amplifier to the minimum. Flip the device on its side and adjust the tone controls to the middle positions. Turn on your system and start listening to your favorite music. Take note of how the bass and upper frequencies have changed.

What Should You Do If Your Subwoofer Has No Speaker Level Inputs?

Depending on the models, the kind of subwoofer, the speaker’s year of manufacture, etc., certain subwoofers may not have all of the inputs and outputs. A subwoofer must have certain features, such as an on/off switch and a volume control. What could be found on a subwoofer includes the following examples:

  • power entry (to connect to the main source)
  • the on/off switch
  • RCA input connectors on both sides
  • crossover settings for the subwoofer
  • know how to alter the subwoofer volume (used to boost the amplifier)

What does it matter if you lack speaker-level inputs? It’s not a train wreck; you just need to seek for an alternative course of action. The low-level input typically connects to your AV receiver via a single RCA wire. Some audio experts might suggest that you just buy a new subwoofer, preferably one of theirs, without asking for your feedback. Nevertheless, subwoofer cables, which are also not required, are available for purchase. It will work if you have an RCA connector laying around.

We have you covered for a different approach.

How to Attach Subwoofer Level Outputs to Speakers

How To Connect A Subwoofer To Speaker Level Outputs?

Verify Your Receiver’s Specs.

With the right preparation, connecting a subwoofer to your outputs is a simple task. First, check the receiver’s parameters. No plugs should be pushed into any outputs. If you don’t have the manual, Google the model of the receiver to get the specifications, or have a look at the receiver’s handbook. Using the inputs and outputs, you will be able to determine your possibilities.

Several modern receivers feature a separate output for subwoofers. Using this output, you may connect your receiver and subwoofer. Your sub will receive any low-frequency effects signal.

Verify Your Subwoofer’s Specs.

On your subwoofer, look for the input or output connection choices. Again, you may accomplish this by consulting the subwoofer’s handbook or looking up the model on Google. Moreover, look for any outputs and inputs needed to connect your sub to a receiver or amplifier on the rear of your sub. The connection may be on the front or side of your subwoofer as well.

It saves time after you know the parameters. You’ll be aware of what to plug into which input or output. Once you’ve planned and checked your equipment, the setup is pretty simple.

Attach the front and back of the subwoofer using two speaker wires on the left and right audio channels.

A alternate arrangement involves using two speaker cords as opposed to only one. When working with contemporary speakers that have a specific output for amplifiers or receivers, we use one speaker wire. The two speaker cables are mostly used to connect to the front and rear of the subwoofer. This link will be made between the right and left audio channels. the following steps:

  • From the left and right audio channels, connect one of the speaker cables to the front of the subwoofer.
  • Run the additional wire to the sub’s back.
  • To change the bass, use the filter on the subwoofer.

There are occasions when you would rather utilize a speaker connection than the speaker wire. The connector’s primary function will be a high-quality audio connection. Three ends of the connection connect to the receiver, while one end connects to the subwoofer. These are the steps for the alternate connection-establishing method:

  • Check to see if your speaker has the required connector connection types.
  • the receiver with the three wires connected.
  • The left and right audio channels’ two positive ports should receive the wires.
  • The last wire, which may be connected to the left or right audio channel, should be connected to the negative port.

Both approaches will produce a strong audio connection. Until you change the bass level on your subwoofer, it will remain the same.

To make the audio clearer, change the subwoofer’s filter.

It’s time to adapt to the required output once you’ve decided on the subwoofer and receiver connection type. The filter can be changed to improve audio clarity. This implies that in order to have a lot of bass, you must balance the audio and high bass levels. The song sounds best when there is some bass present. You don’t want your music to have any buzzing or scratching. Make sure you find a balance because amplifying your music might also amp up the bass.

To test signal emissions for a more accurate harmony, you can use some specialized instruments and equipment.

Take Use Of Your Subwoofer’s Bass

Because the difficult work has been done, there is no reason to worry right now. You may enjoy the sounds by placing your system in a cool, well-ventilated environment. The sound effects, dialogue, and explosions all have more bass to them if your sound system is used as a home theater! Take pleasure in the sensations, but be sure to keep the volume down.

How To Adjust The Speaker Output Volume

You can independently adjust the volume of your subwoofer and speakers. Although it might not be simple, it is doable. It all boils down to balancing the bass and the music’s loudness. Sound is produced by the system’s components working together. Just adjust the speaker level to create a preset sound for your subwoofer. adjusting the sound while maintaining a steady bass.


You can provide your subwoofer a powerful output signal. It makes no difference if you’re using a new amplifier, an older receiver, and a subwoofer that’s both young and old. One can draw a relationship. You may easily enjoy your music by pressing a button. It has never been so simple to connect a subwoofer and speakers!
