The Best 12 Inch Subwoofers Buying Guide

Subwoofers are literally all about that bass. They are a type of loudspeakers which are designed to produce audio of low-pitched frequencies. Although they are usually seen at events such as concerts, consumer-grade models are sold for home and vehicle use.

Car subwoofers, as the name implies, are a smaller range of subwoofers made specifically to fit inside cars and other vehicles. According to Nick, they are generally made up of about eight parts, with the voice coil and the diaphragm being the most vital ones. The voice coil is the part which creates the pulsating vibrations by picking up an electrical charge from wires. These vibrations produced by the voice coil then goes into the diaphragm and churned out as the sound waves I hear from the subwoofer. The diaphragm also helps in making the sound the subwoofer produces to be louder.

Subwoofers come in a wide array of varieties depending on factors like size, power range, frequency range and enclosure type among others.

Car subwoofers usually come in three types.

Passive subwoofers. This is the most basic type of subwoofer. It is a subwoofer housed in an enclosure and which needs an external amplifier to work properly. They can be further modified to fit the needs of the user as they come in various sizes with different features.

Powered subwoofers. If you’re looking for a subwoofer that can produce great sounds at mid-range frequencies, Nick recommends you go for powered subwoofers. This is also a good choice for those wanting to save on space in their cars as powered subwoofers are set up with their amplifiers inside their enclosures.

Vehicle-specific subwoofers. This type is another great choice if you want to save on space as these subwoofers are made to cater to specific types of vehicles. You’ll surely find a setup that will work for the vehicle you have. A downside of these however is that they aren’t that powerful when it comes to sound.

Aside from type, here are other factors you should consider when looking for the best 12 inch car subwoofer.


This refers to the ability of a subwoofer to handle the power that runs through it. Experts believe that RMS or root-mean-square is a better gauge than peak wattage when determining an audio equipment’s power. Thus, a car subwoofer with a high RMS will produce more bass.

Frequency range

This determines the range of sounds that a subwoofer can produce. Since you’ll want good bass sounds, Nick recommends you choose a subwoofer with a frequency range beginning from as low as 20 Hz up to 80 Hz.


This is another important factor you need to consider as a subwoofer’s sensitivity works together with the power to produce high outputs. Nick says that going for a subwoofer with a high sensitivity rating will require less power to produce a similar sound as a subwoofer with a lower sensitivity rating. Sensitivity is measured in decibels (dB) with 89 to 95 dB being the recommended range.


Valued in ohms, impedance is the measure of load value that your subwoofer will present to the amplifier. According to Nick, 4 ohms is the most common impedance among car subwoofers although 2-ohm and 8-ohm subwoofers can also be bought. Impedance, along with power, will determine what type of amplifier will be a great match for the subwoofer you’ll eventually choose.

Type of enclosure

Enclosures are usually sold separately from subwoofers. They are a sort of sealed box which houses subwoofers and greatly affect the quality of sound they’ll produce. Nick recommends getting ported or bandpass enclosures as they produce more volume. To learn more about the different types of enclosures, check out this guide.

A number of voice coils.

Subwoofers can either have dual voice coils (DVC) or a single voice coil (SVC). Although, SVCs are common, DVCs might be a better choice for those looking for more flexible wiring, Nick says, but in the end, the decision will depend on the number of subwoofers and type of amplifiers you’ll install.

You can do this by starting with choosing the best car 12 inch subwoofers that will fit your car space, personal preference and budget. This can get overwhelming, but if you keep these reminders and factors in mind, I am sure that you’ll find the what you’re looking for.
