Buying Guide For subwoofer that fits under seats

Buying Guide For An Under Seat Subwoofer

Many people decide to upgrade their car audio system at some point because the system no longer performs adequately or they just desire an improvement. This process should not be rushed, since there are so many different factors to take into consideration. The under-seat subwoofer is the major component of an audio speaker, so it is crucial to choose carefully. This component is the best and only way to improve the performance and sound of your car audio system. Below, you will discover more information and what to look for when buying a new under-seat subwoofer.

Different Types

A component sub is basically a speaker without all the extras. When buying a component sub offers more flexibility, since you will purchase the other components that make up the audio system separately. Most people will buy a component sub so they can customize their audio system as they see fit.

An enclosed sub is another option, which offers little flexibility. You will either need to invest in an expensive enclosed sub that includes all expensive components, leaving you little room to make any alterations. However, many people will choose to go this route, because it offers much more convenience since the unit includes a subwoofer and prefabricated enclosure. Now, you will need to invest in a separate amplifier for this setup.

RMS Power

The specifications will be the determining factor of how well the subwoofer will perform and the quality of sound. The RMS power is actually the total amount of continuous power a subwoofer can handle. In fact, the RMS is the most accurate measurement of the subwoofer’s power. As the RMS power handling increases, so will the loudness capability. It is important to note that it’s better to overpower than under-power any type of speaker.

Sensitivity Level

Sensitivity is associated with the low-frequency output capability. As the sensitivity level increases the amount of power needed to reproduce the same level of sound will decrease.

Frequency Range

Another very important specification is the frequency range, which basically describes the lowest level of sound frequency a subwoofer, is capable of producing. However, the sound frequency can be altered by the enclosure, so be sure to choose a high-quality enclosure that is designed specifically for a particular brand subwoofer.

Voice Coils

When choosing a new subwoofer, you will need to do some research on the type and number of voice coils it offers. For a car audio system, your best bet will be a subwoofer with two embedded voice coils or dual voice coils, because these are much easier to wire. However, most subwoofers are only embedded with one voice coil unless you are willing to pay extra.

Subwoofer Size Options

If you are looking for louder sounds, then you will need to choose a large subwoofer. A small subwoofer will not produce a loud sound, plus the enclosure type and design of the subwoofer can alter the sound effect and performance. Your best option will be a large subwoofer, especially if you are into playing your music at the maximum volume.

Under Seat Subwoofer

The under-seat subwoofer is listed under the “vehicle-specific subwoofer” classification because they offer space-saving benefits. These subwoofers are perfect for compact vehicles that have limited space for additional equipment. If you are looking for a drumming bass, the under-seat subwoofer is an idea.

Powered Subwoofer

The powered subwoofer is similar to the enclosed subwoofer. Except that it includes an amplifier along with the subwoofer, which is stored inside of an enclosure. These typically do not take up very much space, but most people tend to install them in the trunk or on the floor behind the driver’s seat.
