The car sub plays a very important role when listening to music. It is used to give depth to your audio system and offer a fuller sound. However, there are certain factors and aspects that you should take into account when purchasing them in the store. Because everything will depend on your needs, requirements, and certain specific characteristics.

Therefore, in this article, we will give you a quick guide to buying car subs. What it is and which type is best for you to install comfortably in your car and, thus, enjoy its benefits.


What is a car subwoofer?

Seen from the outside, the car sub and the installed speakers have almost the same design, but functionally they are very different from each other.

The types of speakers are distinguished according to the sound results. Like the woofer for low sound output, the midrange for medium sound output, and the tweeter for high sound output.

In general, speakers are the means used to produce sound from electrical energy. The bass or subwoofer is a bass speaker system that can have lower frequencies. Its main function is to produce sound from 10 Hz to 200 Hz. A full sound will have good musicality with a typical frequency range of around 20 kHz - 29 kHz. The sub will pick up and produce low tones under the speaker and the resulting sound will be smoother.

Now, there are certain characteristics that you should take into account when purchasing a car sub. Let's take a look at the main ones:

Power: Check your RMS power. When checking, make sure the amplifier can handle that amount of power. All subwoofers require amplifiers.

Sensitivity: Subwoofers have a higher sensitivity rating. They require less energy to produce the same amount of sound.

Enclosure: The type of sound the subwoofer will produce depends on the enclosure or type of box in which it is ported.

Number of voice coils: There are single and double voice coils. Doubles provide more flexibility when wiring sound systems.

Size: If you want the system to play music loud and low and also have enough space, choose the largest subwoofer possible. However, don't underestimate the small one, if installed correctly and with the right type of box then it can perform as well or better than the big ones.
