A standard speaker system, be it computer speakers or native car speakers, cannot provide high-quality sound. Conventional speakers reproduce sound located mainly in the frequency range that distinguishes the human ear. A subwoofer is necessary for playing a low-frequency audio signal. In order to fully enjoy your favorite music, you should choose the right device and make a competent connection.

The characteristics of the "subs" clearly show how they differ from ordinary speakers:
- the frequency range has artificially established boundaries, usually this value is 40-200 Hz;
- the product is equipped with a large diameter sound emitter - for example, with a device for home use it is from 30 to 50 cm.
Subwoofers have a simple design, but are divided into several types: closed, open, active and passive.
- Passive. Their design is very simple. They have a low-pass filter and a large speaker. To "swing" such a device will need an amplifier. The device is unable to process or convert the signal.
- Active. For their work does not require an additional amplifier. A speaker and circuits for filtering control are mounted in the device case. The product is capable of processing and amplifying the audio signal supplied to it. It has a significant advantage - an active subwoofer is easy to install in an already prepared audio system.
- Closed. They have a robust housing. Most often, closed type passive "subs". Such products provide good sound, do not distort the audio signal, do not cause resonance and reverb. However, they have their own drawback - the larger the diameter of the installed speaker, the greater the power required to “swing” its membrane.
- Open. This option is installed immediately in the prepared car body, most often in the trunk. With this mounting option, the device will use the entire volume of the cabin to form deep and rich bass. The disadvantage of this “sub” is that it is quite difficult to achieve high-quality sound.
ATTENTION! When using filtering, the frequency maximum that an open type product can achieve is 100 Hz.
Can I connect speakers to the subwoofer
Connecting other speakers to the active subwoofer is quite simple. The passive version does not have a standard audio signal amplifier, so you will need to purchase and install it. If this is not possible, then the “sub” can be connected directly to the speakers. However, in this case, the sound quality will be insufficient. To ensure sound filtering, an additional filter can be installed.
ATTENTION! The filter is able to slightly enhance the audio signal supplied to the acoustics, but the sound quality will increase slightly.
Thus, the best way is to use an amplifier. So the load on the speakers is significantly reduced.
How to connect speakers to a subwoofer
If you are connecting regular speakers and a subwoofer, you first need to make sure that you have the appropriate connectors on both devices. The following methods are commonly used:
- Using cables with plugs 3.5. This is the most common connection method, since 3.5 jacks are usually present on all audio devices.
- RCA These wires are divided into a pair of cables that supply sound from the left and right channels.
- Cables with terminals. The cables at the ends have special terminals that need to be latched or screwed. It is important to observe the correct polarity.
Installation of the device in the car is somewhat more difficult. This requires:
- to prepare a place where the "sub" will be mounted - after which wires from the radio are brought to it;
- all cables must be hidden under the car upholstery;
- the cable should be carefully fixed using clamps, and in the place of installation of the subwoofer, you need to lay the material, providing good cushioning;
- the amplifier and “sub” must be located at a sufficient distance from each other and securely fixed;
- both products are connected using wires that need to be inserted into their respective sockets.
ATTENTION! The best option is to install cables on the roof of the car. So the probability of their damage is reduced.
The procedure for connecting speakers and a subwoofer is quite simple. To achieve good sound, it is necessary to comply with all requirements, use high-quality equipment and reliably fix all connections.
