Important Things You Need To Consider Before Buying A Car Subwoofer

A subwoofer is a type of loud speaker that reproduces low pitched sounds in order to give a distinctive bass sound. There are many things to consider when buying a subwoofer.

First of all, you need to consider how much space you have available for the subwoofer. This will help you determine which size subwoofer will work for you. If you’re also looking at style, you might also want to consider the different shapes available. Features such as type of enclosure, sensitivity, resonant frequency, power handling, excursion, and Xmax should be considered before buying a car subwoofer. You should also take into account the budget you are working with as well as the important factors below:


Subwoofers come in varying sizes ranging from 8 inch to around 21 inch or maybe 6×9 inch, 6.5 inch subs. Before buying a sub, you should ensure that you get the correct measurement of the space that you wish to fit the subwoofer in. This will enable you to select the correct size of subwoofer for your car.



Subwoofers usually come in different shapes such as circle, triangle, rectangle and pentagon. In terms of style, this is a good variation. In terms of sound quality however, the circle ones are said to be the best. The rectangular ones tend to allow more air flow as they provide more surface area.


Enclosure Type

The subwoofer enclosure may be sealed, ported or bandpass. This significantly affects the sound produced. The sealed ones give a more precise and clean sound but require more power to create a high volume like the others. A ported subwoofer creates more boom and is louder; however, it is harder to tune. A bandpass subwoofer is also louder; however, the box is often large so this will not work if you have a small vehicle.



The higher the sensitivity rating of the subwoofer, the less power it will require to create the same volume as one of a lower sensitivity. The sensitivity is usually given in a number in terms of the sound pressure level (SPL). It is best to assess which one fits your needs. If you happen to have a low power amplifier, it is best to get a subwoofer with a high sensitivity.


Power Handling

The continuous power handling is measured in RMS rating, which is what you want to look out for. The more power you have the more sound you will get out of the subwoofer. You should ensure that the power handling of the subwoofer matches the power output of your amplifier.



In addition, your budget is an important thing to consider when purchasing any equipment for your car’s audio system. A subwoofer can be an expensive electronic component for your car. If you get a cheap one, you may end up with one of low quality. To prevent going too cheap and getting something of a low quality, you should first decide on the features of the subs that you desire to have and then seek out a fair price for one that has all the features you want.


Other Things To Consider

You should also consider the frequency range of the subwoofer, as this will tell you how low the sound output of the subwoofer is. The frequency however, may not tell you the actual sound output, as the enclosure type you choose may adjust the sound you hear. The number of voice coils is also important and many car owners prefer dual voice coils for their audio systems as they offer more flexibility in the wiring. The impedance of the subwoofer is also important and you should ensure that the impedance of the subwoofer matches that of your amplifier. The impedance gives the measure of the electrical resistance in ohms.


Final Say

The bottom line is, it is important to consider the features that you seek in a subwoofer before buying one. Once you have decided on the features that you want, including the size and shape, you then need to consider your budget. Ensure that you do not give up quality for a cheap alternative. If you shop around, you can find good prices for good quality equipment. Check the subwoofer that you will purchase to make sure the impedance and power handling are similar to your amplifier. Once you know all the features you want, you should not have a problem in finding the right and perfect subwoofer for your car’s audio system.
