Best subwoofer amplifier
The best subwoofer amplifier is always a combination of quality and power! It is necessary for a passive device, since active subwoofers are equipped with it at the factory. However, not every motorist knows exactly how to choose it. After all, the right choice is the key to success. If the amplifier is not of high quality, the speaker system may not sound as desired. Knowing which amplifier is best for a subwoofer is very important for setting up your car's sound system yourself.
How to choose an amplifier for a subwoofer in a car
When choosing a device, you need to take into account a number of basic characteristics, namely:
- output power;
- frequency range;
- distortion factor;
- presence or absence of filters;
- number of power supplies.
There are single-channel, two-channel and four-channel systems. However, the most important parameter is power. The quality of the bass depends on this.
Important . The low-frequency unit often overheats due to lack of power for the channel. It is necessary to select a device when the amplifier power is greater than that of the speaker. If this parameter is equal, then overheating will occur at high volume, as a result of which the device will break.
All these factors must be taken into account in order to select the optimal device that will fully meet the requirements. As for the brand, experts say: if the device works for the first year without any complaints, it will continue to work stably. If there is a breakdown in the first year, even the products of the most reliable manufacturer will periodically fail.

Amplifiers for subwoofers that are installed in cars are powerful electric drives. They can reproduce any necessary music with excellent quality. Among their most important features is the presence of a certificate of compliance with a specific serial number. This certificate is marked on a brass plate. They also have a special protocol where all existing device parameters are confirmed.

As a rule, modern companies produce amplifiers of fairly small sizes that can easily be placed in a car interior, right under the passenger seat. Such broadband amplifiers have excellent sound, quite capable of competing with AB-class.

Note: by the way, such a device can be placed either near the subwoofer or at a short distance from it. In any case, the device will function normally. The only difference is the length of the cables used.

More about AB
AB are monoblocks that have a lot of advantages:
- Excellent sound quality;
- Quite high power;
- Unlimited sound pressure.
That is, in principle, they are recommended for purchase by almost all car enthusiasts, but it would be unfair not to note one rather significant drawback - they are very susceptible to overheating. Therefore, be sure to make sure that in hot weather there is a cool breeze blowing on them.

Note: if this is not possible, you can install an inexpensive air conditioner in your car.
D-class
In addition to AB class, there are others. So, for example, class D (see Class D amplifier for a subwoofer: advantages and differences from others). It also contains good subwoofers: they have all the necessary filters, both low-frequency and sub-tone. Some models can be combined “through a bridge”. This results in even better sound!

Amplifier and why you need it
First, let's look at this issue. Many people want the music to play loudly in their car. Of course, this requires an amplifier that will breathe new life into car audio, regardless of whether the head unit is good enough.
Subwoofer amplifier and how to choose
So, a car amplifier added to a car’s speaker system can provide the following benefits:
- Not only will the sound power increase, but more importantly, the playback quality will increase. The amplifier in this case can be compared to a pure source of energy that controls the speakers and subwoofer, with virtually no effort.
Note. The great thing about an external amplifier added to a system is that it has no limitations. In other words, music will sound good and clear at all volume levels, even the highest ones.
- Often acoustics are purchased after the head unit has been built into the car. In some cases, the car radio may already have been installed by the car manufacturer or by the former owner of the car from whom you bought it. If the speakers and subwoofer you purchase are high quality, they may require more power to perform at peak performance. Unfortunately, standard car radios are not able to provide this. So you have to use an external amplifier;
Which subwoofer amplifier to choose
- A subwoofer (see Kick subwoofer: review of models and secrets of production technology) is a completely different story. These woofers require more power anyway. And a separate amplifier, even if the last of the active ones with a built-in “amplifier”, is a prerequisite.
Standard stereo speaker systems typically provide no more than ten watts of power output per channel. And this despite the fact that the packaging says 4x50 watts. Such systems don’t even have enough power to overcome road noise, so what can we say about high sound quality?
How to choose an amplifier for a subwoofer
Note. An excellent solution for upgrading your existing stereo system is factory integration with the latest amplifier. As a rule, we are talking about standard car radios specifically designed for a specific car.
An easier way is to upgrade the entire speaker system by adding a compact 4-channel amplifier, which will take on the task of increasing the volume of the speakers and subwoofer.
Amplifier types
How to choose the right amplifier for a subwoofer
As you know, there are several types of amplifier:
- Mono amplifiers that are designed for low frequencies;
- 2 channel. This is needed if the car does not use rear speakers, but only front ones. In this case, a 2-channel amplifier is the most economical and practical option, amplifying only one pair of speakers;
- A 3-channel amplifier will be an option if a subwoofer also plays in a car with front speakers;
- A 4-channel amplifier will make it possible to amplify all acoustics, including the rear one, and also the subwoofer.
How to choose an amplifier for a subwoofer
Most often, a subwoofer is installed in a car when its owner is not satisfied with the sound quality of the standard audio equipment, since the car radio, together with the installed speakers, does not allow listening to music in the cabin at a high level. Small full-range speakers cannot reproduce bass frequencies well, and when the volume level is increased, severe distortion occurs. Some people buy an amplifier first and then a subwoofer, others do the opposite. How to choose an amplifier for a subwoofer in a car and not make a mistake when buying. A very important point is the selection criteria for the low-frequency unit.
Which to choose?
The characteristics of the amplifier must match the speakers connected to it. A discrepancy between the power and impedance of the speakers and the capabilities of the amplifier can lead to failure of the amplifier or a noticeable decrease in sound quality. The input impedance of the speakers should never be lower than that supported by the amplifier.
Before moving on to selecting an amplifier based on its characteristics, you should prepare for the fact that the purchase will be expensive: amplifiers belong to those types of equipment in which an expensive model may be bad, but a cheap model cannot be good. Even the total cost of the components alone (high-quality connectors, heavy aluminum radiator, power semiconductor devices) already amounts to a considerable amount. And, in order not to waste your money, it is highly recommended to pay attention to trusted audio equipment manufacturers such as Alpine and Hertz. Or to more budget, but still high-quality models from Swat, JBL, Pioner, Kenwood, Sony, etc.
Why do you need a car audio amplifier?
Today, many cars are equipped with an audio system at the factory. For most car enthusiasts, the capabilities of a standard audio system are quite enough, and if you do not experience discomfort from the sound quality of the standard radio, and you have never had the desire to turn the volume control to maximum, then you do not need an amplifier. But if the quality of the standard sound does not suit you, or if you want to put a subwoofer in your car and rock it at parties and festivals, then you cannot do without a sound amplifier.
How to choose an amplifier for a subwoofer based on power
When choosing, it is important that the output power of the device matches the load power. Which amplifier to choose for a subwoofer. There are three points of view on this problem:
The rated power of ULF and dynamics are somewhat different from each other. For an amplifier, this is the value at which the output distortion coefficient does not exceed a certain value. The loudspeaker's rated power allows it to operate for a long time without permanent damage. The moving speaker system can be destroyed by mechanical or thermal effects. In the first case, this occurs due to the amplitude being too large. In this case, the diffuser or flexible suspension is destroyed. Thermal stress causes excessive heating and burnout of the voice coil.
Choices.
If you want to connect a subwoofer to an existing audio system, the best choice would be to purchase a single-channel amplifier. This will cost you 6,000-15,000 rubles, depending on the manufacturer and the power of the subwoofer.
If you need an inexpensive amplifier to create an audio system with a pair of speakers and an optional subwoofer of not the highest power, pay attention to three- and four-channel AB-class amplifiers priced from 3,000 to 10,000 rubles.
