The 10 Best Powered Subwoofer for Cars

If you don’t have a subwoofer attached to your car stereo, then you are missing out on the fun that comes with driving to thumping bass beats. Getting a good stereo for your car is half the battle won, the other half includes choosing the best subwoofer to enhance those low-frequency bass tones in the audio. Now, subwoofers come in various shapes, sizes, and watt power. They are available as passive subwoofers or powered subwoofers. Passive subwoofers are usually dependent on an external source for amplifying their audio signals while powered subwoofers have an in-built amplifier.

For the purpose of installing in the car, powered subwoofers are ideal as they are easy to install and require no external power source. So, if you are looking to buy subwoofers for your car, we recommend going for the powered variety.

Now let us look at some important features which a good subwoofer should have and what we, as a consumer, should gauge before we buy the best-powered subwoofer for our car.

Features to check in a powered subwoofer

The market has a variety of subwoofers for sale, all with different features and sizes. So, which one is the best? The answer to this lies in knowing what features are important in a good subwoofer. To help you with this, we are listing the most important things to look and review in a subwoofer before buying one.


The size of a subwoofer plays an important part when it comes to deciding which one is the best for your car. Because of the limited space available in a car, a smaller subwoofer is preferred over a big one for the ease of installation. But, the power and performance of a subwoofer is proportional to its size. So a smaller subwoofer would not give the same level of performance as compared to a bigger subwoofer. Subwoofers come in four sizes, 8-inch, 10-inch, 12-inch, and 15-inch. If you are looking to fit the subwoofer in your car, it is recommended that you do not opt for anything above 12-Inch as then it would pose difficulties in installation. An 8-inch subwoofer would be much lighter and easy to fit but might not deliver a punch. An alternative option is to install two 8-inch subwoofers to get the required depth. Or else, opting for a 10-inch subwoofer is the best choice. The 10-inch subwoofers provide a great balance between compact fit and bass depth. They deliver a deep and punchy bass while also easily fitting in the car. Most of the subwoofers reviewed above fall in the 8 to 10-inch bracket and thus are ideal for installing under the seat. So, the idea is to buy a compact sized subwoofer for the car and if the small-sized subwoofer does not deliver the bass punch, then you can always install two small subwoofers.


Enclosures are a very important aspect to look at while buying an under seat subwoofer. They not only define the sound that will be produced by the subwoofer but are also responsible for its safety. A good sturdy enclosure will ensure that the subwoofer is immune to slight bumps and scratches. Enclosures are mainly of two types- Sealed Enclosures and Ported Enclosures. Sealed enclosures keep the subwoofers in an airtight compartment which results in great sound clarity but falls back on depth. On the other hand, ported enclosures feature a heavy-duty wall or compartment around the subwoofer and also feature space to allow free air passage. This free air-passage helps in achieving greater bass depth but the sound gets distorted due to background noise. The choice between ported or sealed enclosures for the car is simple. For installing subwoofers in a car, we would look for something which is compact and provides great sound quality, and sealed enclosures fit the bill. As for ported enclosures, they are heavy, difficult to install and are more expensive than the sealed enclosures. Thus, opting for sealed enclosure subwoofers is the smarter choice.


Power refers to the Watts that the subwoofer can deliver. Usually, a higher watt power is associated with better performance. But, when it comes to car subwoofers, it is not ideal to go for subwoofers with high watt power. If possible, we should buy subwoofers with RMS watt of equal or less than 800. RMS watt is the level of power that the subwoofer will deliver on an ongoing basis while peak power is the maximum power that the subwoofer can achieve. So, a subwoofer might have a peak power of 1000 W and RMS watt of 600 W. RMS watt is always less than the peak power watts. Along with watts power, one should also check the frequency response of the subwoofer. Lower the frequency response, better is the subwoofer as it can capture even the lowest bass frequencies and accentuate them. A subwoofer’s main job is to amplify the bass in an audio and frequency response plays a big part in that. Sensitivity rating is another important feature where it tells us the measure of sound or decibel that a listener will hear with the amount of power being generated. This means that a sensitive rating translates into power consumption and an efficient subwoofer. Thus, check the sensitivity rating and frequency response of a subwoofer before buying.


Price of a subwoofer is sometimes the clincher when it comes to buying one. People go for the more affordable one rather than the expensive one. It is important to see if the price for a subwoofer is high only because of some features which you do not need like a stylish look, LED lights, etc. But if the price is high owing to higher watts and better sound quality, then it should be considered. Thus, do not always buy the most-cheapest subwoofer and understand the reason behind the high price of a subwoofer.

Hope these tips help you when you go searching for the best-powered subwoofer for your car. Buying a good car stereo is half the work done and the other half is complete when you compliment it with a powerful subwoofer. There is nothing like feeling the bass beats every time you take the car for a spin.
