    Buyer’s Guide

    The following are factors that you should consider when looking for the ideal compact subwoofer for your car.

    Size

    Even though compact subwoofers are designed to fit into smaller vehicles, the amount of space available in a car varies among different models. Therefore, you want to ensure that the subwoofer you like can fit into your car.

    It is therefore advisable to measure the dimensions of the available space in your car before buying a subwoofer.

    Power Output

    The amount of power that a subwoofer can produce determines the volume, and even the quality of the sound that it emits. Power output in subwoofers is defined by peak power and RMS power. Peak power is the maximum wattage that a system can handle in short bursts, while RMS is the maximum wattage that a subwoofer can handle for prolonged periods without distorting the sound.

    Therefore, you want a subwoofer with a high RMS rating, as peak power does not mean much because it is not sustainable.

    Frequency Range

    This refers to the range of frequencies that a subwoofer can handle without distorting the sound. A good subwoofer should handle a frequency range of between 20 and 200 Hz.

    Cone Size

    The cone is the feature that produces the bass sound. Generally, larger cones produce deeper and more powerful bass sounds, as they displace more air. Therefore, if you are into deeper bass, you might want to look for a subwoofer with a large cone.

    Enclosure Type

    Subwoofer enclosures can be sealed, ported, or bandpass. Sealed enclosures tend to have deeper and more accurate bass sounds. However, they also use up more power.

    Ported enclosures have a vent that reinforces low bass response, which makes them ideal for forceful bass, such as that found in heavy rock music.

    Bandpass enclosures, on the other hand, have a design that maximizes slam.

    Conclusion

    Compact subwoofers tremendously increase the sound quality and overall music experience in a car. However, you need to find the one that suits your preferences and budget well. Hopefully, our reviews above will help you find a good system for your car.

    With that being said, we believe that the Rockville RW10CA is the best compact subwoofer on the market today, thanks to its superior design, power and performance. But it is the Rockville SS8P that will give you the most value for your money.
