Correctly setting up and troubleshooting your audio system will allow you to get the highest quality and clearest sound possible. Please note that incorrectly configured speakers, headphones, subwoofer and other elements of the computer audio system will sound unevenly.
Often, the absence of sound, hissing or interruptions in the playback of audio tracks indicate an incorrect functioning of the sound card or old system drivers.
The audio system does not work. Possible causes and solutions to the problem
Before you begin restoring and repairing your audio system, you should understand the cause and nature of the failure. Problems can occur at both the software and hardware levels.
First, check if the speakers are connected correctly. The speaker connection diagram can be found using the image below:
At the first stage of diagnosis, you should try to connect other speakers to the computer; if they work normally, then the problem is that the speakers are broken. If none of your speakers play music tracks, you should check the type of sound video card that is connected to your computer's motherboard. To do this, you need to open the case of the system unit of your personal computer. Then you should find the sound video card on the board and look at its model and version. To check the audio card model, you can also use third-party software, for example, the CPU-Z program, which allows you to view all the technical characteristics of the processor without opening the personal computer case.
After determining the type of sound card, check on the manufacturer's website what types of speakers it supports. There are several types of sound speakers:
- Type 2.1 sound cradle models
- Models of 5.1 type sound cards
- Type 7.1
If the type of connected speaker matches the requirements of the sound card, but there is still no sound, you need to check whether the driver software is installed and configured correctly. A few tips for correctly installing drivers:
- Download all software exclusively from the websites of video card or audio system manufacturers.
- Try to download driver software archives. They always contain all the necessary software that is necessary for the normal functioning of the system.
All of the above options help eliminate the main reasons for the lack of sound from the speakers.

Testing and adjusting sound in speakers
If the speakers are working, but the sound leaves much to be desired, you need to configure it using standard tools of the MS Windows operating system. To start testing and adjusting sound parameters, go to the system control panel using the Start menu.
Go to the sound menu (to speed up the process of finding the desired icon in the control panel, use the instant search in the upper right corner). Select the required speakers from the list of installed sound devices and check in the options whether the drivers are installed correctly (if not, reinstall them) and whether they are connected correctly.
Test the sound at different volumes to check for excessive hiss or other interruptions in the sound.
If your speakers have a built-in microphone, be sure to check the sound recording quality. This can be done using a very ordinary voice recorder. If such a program is not in the list of standard pre-installed software on your OS, you can download third-party software. Good analogues to a standard voice recorder are the programs EasyRecorder, RecordMe, StartRecord. Before launching the program and recording anything, check whether the microphone is enabled in the sound settings (system control panel - sound).
Equalizer settings
High-quality acoustics are of great importance for every user of a personal computer or laptop. A special equalizer can give your favorite music and movie soundtracks a really good sound.
Before you start setting up the equalizer, you should check that the audio system is correctly connected to the sound card. Also check whether all drivers and other pre-installed software required for audio are functioning correctly.
You can use a standard equalizer; it is built into every Windows operating system; however, third-party equalizers, as a rule, have wider functionality and quality of sound correction. Let's look at how to use the built-in equalizer and which third-party programs are worthy of your attention.
The process of setting up the built-in equalizer:
- Go to the Sound menu in the Computer Control Panel (this step is described in more detail in the first paragraph of the article).
- On the menu tab called Playback
- From the list of audio devices that appears, select the speaker. Open the speaker menu.
- In the window that opens, select the properties item - it will open another window.
- In the new window, select the tab called levels. A menu for adjusting various sound parameters of the audio system will open. Setting up sound on a computer involves changing the parameters that appear. In this menu you can configure the sound separately for each of the two connected speakers. Try to set the most pleasant sound level.
- Go to the Improvement tab. In the list of checkboxes that appears, check the equalizer box. After completing this action, you will have access to the sound card equalizer control function. All changes will be automatically saved by the system. You can also return to the original equalizer settings.
The standard settings window for the built-in equalizer in the system looks like this:
The equalizer settings are quite extensive and allow you to customize the sound according to the type of room and personal sound preferences.
Third-party software for setting up your computer's equalizer:
- Equalizer APO. A program with wide and advanced audio equalizer functionality. Suitable for Windows operating systems. The program provides the user with the opportunity to work with a huge number of sound filters and channels. The option to connect to related audio programs is available. The utility does not load the processor, but allows you to quickly adapt the sound level according to the personal preferences of the PC user.
- The program is a sound equalizer that is designed to be placed on the operating system desktop. Allows you to customize the sound according to the type of room and displays sound vibrations directly on your desktop.
Setting up a subwoofer on a computer
A subwoofer is an integral and most powerful element of professional acoustics. The main feature of a subwoofer is that this device can transmit low frequency sound waves. The total frequency range of the subwoofer is from 15 to 200 Hz.
The subwoofer is used in professional audio audio systems, however, an increasing number of users of personal computers and laptops are buying subwoofers for home use. The subwoofer can be connected to speakers. Please note that for the best sound effect, the speakers should have as much power as possible.
First of all, pay attention to the placement of the subwoofer within the room. Incorrect placement of the device may degrade the final sound. The best option for placing a subwoofer is an angle. It is in the corner that the sound will have the most profound effect. Install the subwoofer at least one meter away from the speakers.
After connecting all the subwoofer wiring to the computer, you should perform a number of standard actions: install the driver software and, if desired, use a third-party program to configure the sound on the subwoofer.
Software that will help you customize the sound of the subwoofer:
- JBL-SpeakerShop - calculates the most pleasant sound level. It has a built-in filter calculation module.
- Speaker Workshop - allows you to configure all acoustic parameters. It has a pleasant user interface and fast execution speed.
- Perfect Box. A special feature of the program is the DOS-type interface. This may cause some inconvenience to inexperienced users.
- WinSpeakerz - the program has standard functionality and a well-thought-out user interface.
Adjusting the sound of headphones connected to the audio system
Headphones are also an element of the audio system. Their sound is very easy to tune even for an inexperienced user. To start setting up headphones connected to your computer, follow the instructions below:
- Go to your operating system desktop.
- On the toolbar, right-click on the speaker icon.
- From the proposed menu, select the tab under the name of the playback device.
- In the window that opens, select the sound playback tab and configure the parameter as you wish, or apply standard settings by checking the “Default” checkbox.

If you are using wireless headphones, make sure that the system recognizes and installs them automatically, otherwise install all the drivers yourself. This can be done by using the installation disk or downloading the necessary software from the website of the manufacturer of your headphones.
Some car owners are not satisfied with the sound of the standard radio. The situation can be corrected by installing an active or passive subwoofer. Installing the device in a car is possible on your own, for which you should select the necessary materials and tools, familiarize yourself with the connection diagram and the step-by-step process algorithm. Then installing the equipment and connecting it will not be difficult.
The main differences between passive and active subwoofers
To answer the question about the distinctive aspects of active and passive subwoofers, you must first understand what each of the designs is individually.
What is a passive subwoofer
A passive sub is a design of one or more low-frequency (LF) dynamic drivers enclosed in a single housing, the material of which can be either plywood or wood. In order for such a device to reproduce sound vibrations, it is necessary to connect to an external audio amplifier through a low-pass filter, which passes only the signal band with low frequencies.
A passive subwoofer is a separate unit of speakers, filters and amplifier. Each of these blocks is purchased separately and connected to each other during installation.
What is active
An active sub is a single ready-made acoustic unit, consisting not only of a speaker and a filter, but also an amplification device. Such equipment is somewhat simpler to connect, and there is also an opinion that the sound quality is superior to the sound from a passive subwoofer. But if you look in more detail, the sound quality directly depends on how the settings are made.
The active subwoofer has a built-in amplifier, which saves space in cars with little free space. To connect to the radio, you only need to supply power and an audio signal.
Difference between them
To decide which design to give preference to, it is worth considering the main points that car owners pay attention to when choosing:
- Price indicator - the cost of an active subwoofer is higher, which is due to the presence of an amplifier and other expensive elements in the device.
- Advantages of installation - passive structures are more difficult to install due to the need to additionally install a filter and amplifier. The presence of an amplifier in the active system saves space, which is especially important for small cars.
- Sound quality - many would argue that the sound of an active system should be better. However, the sound directly depends on the correct setup of the system. Based on practice, with high-quality setup of a passive subwoofer, the sound surpasses the performance of the active system.
- Ease of setup - an active speaker system has more advanced setup options, but if a good external amplifier is used, then this feature is nullified.
Pros and cons of systems
The positive aspects of a passive subwoofer include its relatively low cost due to the lack of a built-in amplifier. In addition to this point, the use of passive systems allows you to assemble an acoustic device with exactly the requirements that will correspond to high-quality sound as you understand it. In order to get a subwoofer with optimal sound quality, you will need to select an amplifier, frequency filters, and a set of dynamic drivers in boxes. Compared to active ones, different types of enclosures are used for passive designs: bandpass, bass reflex, and standard boxes. As for active devices, it is difficult to use different types of housings due to the need to accommodate additional electronics.
The main advantage of active is the presence of a built-in amplifier and filter, which allows you to connect the system to a car radio without additional devices. This positive feature is also a disadvantage. Due to the fact that both the speaker and electronics are located in one case, something has to be sacrificed. The main nuance is the insufficient power of the amplifier.
How to install a subwoofer in a car and connect it to the radio
To install a subwoofer, in addition to the device itself, you will need the following tools and materials:
- wiring (power, “tulips” and positive wire to the amplifier and car radio);
- fuse;
- capacitor;
- pliers and wire cutters;
- insulating tape;
- screed;
- a set of wrenches and an adjustable wrench.
Where to install
Installing a sub can be a real challenge, depending on the car model. And it’s not just a matter of connecting the device, but also choosing a place for its installation. As the owner of a minivan or hatchback, the issue of space does not raise any questions, since the trunk is large. With sedans the situation is somewhat different and, as a rule, the sub is mounted in the armrests or on the rear parcel shelf. The most inconvenient body type is considered to be a convertible, since such cars have a small trunk volume. However, if you really want to, you can install the device in question in such cars.
Connecting a passive
Let's consider a sequential algorithm for installing a device. The installation will take about 1–3 hours, depending on the experience and model of the machine. One of the difficult steps is laying the power cable to the amplifier. Since the subwoofer is mounted in the trunk, all wires must be routed through the cabin to the power source. Before starting work on the battery, remove the terminals, which will eliminate the possibility of a short circuit.
- The first thing that is necessary is to find a technological hole, which is closed with a special plug. On domestic cars it may be missing, as well as the hole itself. Therefore, you will have to drill it and, after pulling the cable, seal it with sealant. It is best to insert a piece of hose into the hole to prevent chafing of the wire.
- The wiring in the engine compartment can be located in the standard harness and led out into the cabin. You first need to decide where and how the power cable will be laid. For wires in some places you will need to remove the trim, as well as the sill trims. Avoid kinking or pinching the wiring. After installation, all facing elements are installed in their places.
- In the luggage compartment, the wires to the amplifier are also routed through a hole in the body. Power is connected to the device in compliance with polarity.
- After connecting power to the amplifier, it must be connected to the radio. In this case, you will need wires of the “tulip” type, as well as a wire that allows you to control the power of the amplifier. To dismantle the radio, special keys are used, but you can carefully use a knife or a screwdriver of a suitable size.
- We connect the “tulips” according to the colors of the connectors. If it is necessary for the subwoofer and the radio to be turned on simultaneously, then use the corresponding positive wire.
- Then we pass the wires together with the power cable through the interior. We connect the “tulips” to the amplifier.
- If a power wire was connected to the radio, it should also be supplied to the amplifier so that the devices turn on simultaneously. We look for the terminal and connect it to the power cable of the radio.
- All that remains is to connect the subwoofer to the amplifier. When installing a two-channel amplifier, for power distribution, both channels are connected to the device in question.
The high-level adapter is used for radios without line-out connectors. The device converts the signal from the radio output into a linear signal
Connecting a subwoofer from a computer to a radio
Sometimes the quality of standard music in a car is not satisfactory and various ideas arise to improve the sound. One of the issues is connecting a computer subwoofer to the radio. In fact, the device can be connected in two ways: by supplying power through a 12/220V inverter or by finding the necessary contacts (+12V) on the amplifier board for the subwoofer. To do this, you need to arm yourself with a tester and have some experience in radio electronics. Having sorted out the power supply, we apply an audio signal to the subwoofer input, taking it from the linear output of the radio, using a shielded cable of the required length.
Crossover connection
Before considering connecting a subwoofer via a crossover, you need to understand what this device is. Crossover allows you to separate frequencies into ranges, i.e. plays the role of a filter. For example, there are speakers called “tweeters”. If you did not apply a frequency filter, then a signal from the entire frequency range would be supplied to the dynamic heads - from low frequencies to high frequencies. Without signal separation, the detail of the music will be worse. Crossovers come in active and passive types, as well as one- and two-way.
Pros, cons and connecting a passive crossover
A passive filter has no active elements, i.e. it consists of inductors, resistances and capacitors. This leads to a significant disadvantage - loss of signal power. Also among the disadvantages are restrictions on peak load, which leads to rapid failure of the device. To connect a passive crossover, it is placed directly in front of the load, i.e. in front of the dynamic heads. In this case, only one amplifier can be used, which is an advantage. Such filters can be built into the acoustics or form a separate unit.
Pros, cons and connecting an active crossover
An active filter is installed in front of the amplifier, so it is impossible to use one device to amplify the signal. In this case, the speaker is connected to a separate amplifier channel, regardless of the type of frequencies. One of the advantages of an active filter is the ability to fine-tune frequency cuts. It is this factor that determines the higher cost of such a design compared to a passive one.
Security measures
- Any work in the car related to electrical equipment must begin with de-energizing, i.e., disconnecting the terminals from the battery.
- All connections must be reliable and safe, for which seals, electrical tape, clamps, and special corrugation are used.
- Only high-quality wires are used for installation.
- The choice of fuse must be carried out in accordance with the passport data of the connected devices.
- Acoustic equipment in a car must be mounted conveniently and securely.
Video: connecting a passive subwoofer
Installing a subwoofer in a car allows you to get decent sound quality. If a passive design is used, each of the system devices can be selected according to the specified characteristics. For self-installation, it will be enough to purchase the necessary components and familiarize yourself with possible connection diagrams, and you can save on visiting a car service center.
Subwoofers are divided into active and passive. The former are distinguished by the presence of a built-in audio amplifier and can be connected directly to the linear output, without external amplifiers. The subwoofer itself is a device with a large speaker designed to reproduce frequencies that are at the lower limit of human audibility (ranging from 20-40 Hz). They give the sound of the multi-way stereo system in which they are included a special velvety and deep sound. The speaker is mounted in a square housing, which is most often made of MDF or chipboard boards and has a stroke of up to seven centimeters during sound. The larger the diameter of the low-frequency emitter, the better the bass will be played.
An active subwoofer has a built-in so-called crossover, which cuts off high frequencies and transmits them to other speakers. Experts who know how to connect a subwoofer to a computer say that before purchasing it, you must first find out its compatibility with the computer’s sound card. After all, not all audio cards support its connection. In addition, you need to make sure that the number of sound card outputs is equal to the number of speakers. The subwoofer should have a separate output dedicated to it, but if it doesn’t exist and you want to connect it, you can plug the plug from it into the output for another speaker. In this case, it is better to experiment with the sound quality of the entire system to select a pair of speakers that can be turned off. There may be a variant of terminals, then the wires will need to be screwed to the speakers and to the active speaker.
If the audio card does not have a sufficient number of outputs, then you can wire an active subwoofer to a speaker system that will be connected to the computer. In this case, it is better to have on hand detailed instructions for connecting the sound system to the corresponding computer audio device or, if possible, trust the knowledge of a specialist who understands such issues. In the case where the speakers are connected to each other by wires, you need to make sure that they are firmly secured in the terminals, because otherwise noise and clicks will creep into the sound of the system. Install the bass speaker between the front speakers, otherwise the sound will be distorted at a distance from the system towards certain frequencies. As an option, you can place a subwoofer at each of the speakers. The bass reflex tube (tube) should not be close to the wall of the room, otherwise a “booming” effect will be observed.
Independently connecting an acoustic system, if you have detailed instructions for all the equipment necessary in this case and the desire to connect an active subwoofer to a computer, can become a fascinating process that will delight you with its results for a long time. Cards designed for connecting subwoofers to them, including including active ones, in the vast majority of cases an accompanying program is included, which is installed on the computer and allows you to configure work with the connected device in a step-by-step mode. It usually has a simple, intuitive interface that offers many sound options.
There is no standard for programs from different manufacturers, so you need to understand each specific case yourself or you can contact a specialist who is well versed in this area. In any case, the software for the sound card includes an equalizer that allows you to customize the sound for each specific room. If setting up the sound card turns out to be an impossible task, then you should contact the support service of its manufacturer. There they will explain the features of their device and answer many questions. Ideally, this should be done before purchasing an audio card or subwoofer. In this case, there will be no problem of incompatibility between them and the time spent on installation will give the expected results.
Absolutely every modern user has heard about a device called a “subwoofer,” but not everyone understands the principles of its operation and why it is needed in general. A subwoofer is a device that is widely used in acoustic audio systems to fully convey the full range of sensations from music. It is engaged in the reproduction of low frequencies that are physically perceived by humans. Wonderful device, right? Purchasing such a device is a great idea, but how to connect a subwoofer to a computer? We'll talk about this today.
Subwoofer
Those who did not have this device have never heard high-quality bass. A distinctive feature of low frequencies is their excellent propagation in confined spaces, which sometimes makes it very difficult to determine the sound source. It is this property that allows you to place the device in any convenient place where it will not disturb anyone. And the most important thing is that the location does not affect the listening experience in any way.
Also, this gadget has large dimensions, which directly affect its power.
Important! If you want to watch movies with complete sound immersion, then be prepared to allocate a separate corner in your apartment to this technology. Over the past decades, these devices have become extremely widespread. They can be used absolutely everywhere: at home, at work, in clubs, in transport and other places.
Classification of subwoofers
Before purchasing such a device, you need to familiarize yourself with the main information about the devices in order not to get into a tricky situation after the purchase. We got acquainted with the definition itself, and now it’s time to find out what types of “buns” exist, how to connect a subwoofer to a computer without an amplifier and with it. Let's start with the fact that devices are active and passive.
Active
Subwoofers of this type are a whole system, which is equipped in one housing with the required dimensions and shape.
Important! Essentially, this option is the most convenient for a novice user who has no idea about frequencies, electronics and school physics.
But you still need to understand that the housing contains not only an amplifier and a speaker, it also contains frequency filters. It is with the help of them that the operation of the “roll” is coordinated with the connected sound sources. Additional control panels also play a significant role, allowing you to configure the device for any occasion. All together is responsible for that wonderful bass that you heard.
Passive
This device is slightly different from the previous one. Here, a powerful speaker is simply located inside a box with certain geometric dimensions and shape.
Connecting an active subwoofer to a computer
How to connect a subwoofer to a computer? In this case there should be no problems. First of all, you need to make sure that the audio card of your personal computer can work with the device. This information can be found in the documentation that comes with the device or from a sales assistant at an electronics store.
The connection itself can be made in different ways. It all depends on the available connectors, outputs and potential capabilities of the amplifier or audio board.
Important! All connectors on the “bunch” have different colors and they must match the colors on the PC sound card. If suddenly there are not enough connectors, then do not despair. Absolutely under each connector there are instructions with a purpose, but if suddenly the number of connectors on the sub and the card does not match, then you will have to experiment with another pairing method - audio input for speakers.
Materials for work
If we have figured out all the intricacies, then let’s get down to our business: how to connect a subwoofer to a computer? To connect via a connector intended for speakers, you will need to acquire an adapter from a 3.5 mm “jack” to the simplest two “tulips”. This wire can be purchased or soldered; there is nothing complicated about it.
Operating procedure:
- If you have all the consumables on hand, then you can safely connect the amplifier and stereo speakers, not forgetting about the polarity.
Important! Do not confuse the polarities if you do not want to prematurely ruin the sound of the audio system.
- Now we need to connect our “tulips” to the output of the amplifier, and the 3.5 mm jack to the output of the audio card.
- The “bulka” is connected to the amplifier through a specific connector. If there is none, then to the speaker terminals.
- Now we turn on the PC, wait for the operating system to fully load and start the amplifying element.
- All that remains is to configure the sound parameters the way you want.
The device is ready to use!
Connecting a passive subwoofer to a computer
The connection can be made using an amplifier, if one is available, of course. But if you still don’t have it, then run to the store for a new purchase. Only after purchasing it can you start connecting it by analogy with an active gadget.
But there are cases when you want to connect a “bunch” without an amplifier.
Important! It is worth understanding that there is a risk of danger when using a subwoofer without an amplifier.
The connection occurs by analogy with ordinary speakers - parallel connection to the circuit. Please also note that additional resistance will adversely affect the volume and sound quality of the system. Yes, the bass quality will not be as good as it was in the previous case.
Connecting an active subwoofer to a computer is somewhat different from installing a conventional sound system; here you can no longer get by with a regular audio adapter, since connecting a subwoofer requires an additional connector.
