Best Powered Subwoofer for Car and Truck

There was a time when audio equipment like subwoofers could only interest studio experts or highly passionate audio enthusiasts in their home. They were expensive and complex to understand. Today, home audiophile type of performance is now possible in any type of car, truck, suv or van.

One of the best additions or upgrades you can do is to add a subwoofer. I recommend finding a place to mount a subwoofer in an existing location. If you can’t find one, a self-enclosed powered subwoofer may be the next best option.

Important Points About Car Powered Subwoofers

Powered subwoofers can perform several diverse functions, and therefore, it is great to have them in your cars, trucks, etc. The concept of powered subwoofers dates back to the 1980s when manufacturers would pre-install them. In general, the speaker space available in older car models was very compact. So, the buyers didn’t really have any other option. 

While these pre-installed powered woofers worked very well, the only problem was that the bass could not be increased, and the volume was very low. To get rid of this problem and manage the space crunch, people started using powered subwoofers.

Why People Choose Car Powered Subwoofers

Those who are aware of audio equipment must be knowing the difference between subwoofers, amplifiers, and boxes used in cars. Car powered sub movers are a little different than all three.

The main difference is that powered subwoofers can increase the bass component of sound. However, they can be easily installed in the limited space available in cars, something which is difficult when you choose to fix all three separately. 

Modern-day powered subwoofers are designed to give many other benefits too. Most of them have a special-purpose amplifier also.

Besides, they have adjustable controls that can work in tandem with your regular car stereos. Powered subwoofers are very easy to manage because all the crucial connections are present in a single central area. 

The design and features offered by a powered subwoofer help in reducing the costs as well. Since the unit has a compact design that fits snugly in the speaker enclosure and comes with a dedicated amplifier, there is no need to spend money on additional accessories. In all, it is a modular accessory that will help car owners a lot. 

Pros And Cons Of Powered Subwoofers

Till now, we have discussed many high-quality powered subwoofer units that are available in the market. However, these units have their share of problems as well. So that you have realistic expectations from your power subwoofers, here are a few pros and cons you must know. 


We have already discussed several benefits of installing powered subwoofers in the car. Some of the most attractive features of a car subwoofer are its easy installation, affordable price, and the option of detaching the unit whenever you leave the car. 


Even though these subwoofers can derive power from strong car batteries directly, there are limitations regarding the peak power that can be obtained.

If you are someone who wishes to get a very high peak sound intensity and expect that a powered subwoofer can provide volume levels equivalent to a separate amplifier, you will undoubtedly be disappointed.

Although powered subwoofers have an amplifier, it is very small in size and is not as competent as a separate amplifying device. 

Important Factors To Consider

1. Sealed Enclosure

In all the powered subwoofers mentioned in our article, the main circuit is enclosed by a sealed box. While the sealed units are less likely to get damaged, the enclosure is more important for producing better quality bass sounds. 

The other type of powered subwoofer that is available in the market is called the ported subwoofer. While it also provides almost all expected benefits of a subwoofer, the lack of an enclosure prevents it from creating a better bass experience. 

2. Materials Used

The material with which the powered subwoofers are made also determines the quality of sound produced. Generally, four main materials are used in making these units.

These include- Aluminum sheets, Medium Density Fibreboard, Polycarbonate Lexan, and Plywood. If any of these is present in a powered subwoofer unit, it will give you better performance than other subwoofers. 

Best Powered Subwoofers – Conclusion

With this article about the best-powered subwoofers for cars, you are well equipped to choose the one that best suits your purposes. Knowing the materials and the available features is important for finalizing a powerful subwoofer. There are variations in the kind of bass that different materials produce and their prices. 


  1. Are Powered Car Subwoofers Any Good?

    If you find an ideal powered subwoofer unit for your car model, you will not have to look for any other subwoofer, amplifier, box, etc., separately. A good powered subwoofer will take care of all these needs and give a perfect quality sound. It will help modify the sound intensity and bass, thereby giving you a better acoustic experience every time. 

  2. Do Powered Subwoofers Ruin A Car?

    Good powered subwoofer units do not even require much modification for installation in the car interiors. However, the subwoofers can damage a car if they start drawing high amounts of power from the car’s battery. In this case, the battery starts becoming weaker and dies out frequently. Moreover, you should not use a powered subwoofer if you already know that the battery is becoming weak. 

  3. Can I Put A Powered Subwoofer Under The Seat?

    Underseat subwoofers are produced and sold separately by manufacturers. Not all subwoofers can be used for this purpose. You can check with the dealers if the powered subwoofer unit you have bought can be installed underneath a seat. However, in most cases, you will have to buy a separate under-seat subwoofer, as a powered subwoofer may not work well in this case. 

  4. Can I Use A Powered Subwoofer Without An Amplifier?

    As stated before, many powered subwoofer units have their own amplifiers, meant for special purposes. While this amplifier is not as strong as a separate high-quality amplifier, it is more than enough to produce high-volume sound in most cars. So, if you do not require very high-intensity sound output from your stereo, a powered subwoofer can be used without an amplifier. 

  5. Do Powered Subwoofers Need Warming Up?

    All subwoofers respond differently when turned on. Powered subwoofers derive electricity from the car itself. As the car engine takes some time to get warmed up, powered subwoofers, too, require time to work efficiently. Thus, to answer the question, powered subwoofers have a warm-up period.
