Common sizes include 10 or 12 inch subwoofers with each delivering hard hitting bass. Most car audio enthusiasts stick to the bigger brands such as JL Audio but there are many cheaper alternatives that offer similar performance.

How We Rated The Car Subwoofers

As well as installing many different types of subwoofer from multiple brands in our own cars, we also based our recommendations on a number of factors. The factors that were considered for this article included their performance, build quality, sizes available, ease of installation and value for money.

Car Subwoofer Buying Guide

The market for car subwoofers is very saturated. However, this means that every brand is competing to be the best, which results in a range of new features and competitive pricing. Deciding on the best option for your car can be difficult but this is where our comprehensive guide comes very useful.

In order to achieve quality bass, you will need to find the best rated car amplifier for your specific subwoofer. Failing to give the subwoofer the correct signals can result in poor sound quality to both the subwoofer and any car speakers.

To help you make an informed buying decision, we have produced the below guide regarding car subwoofers.

Subwoofer Box Size

The subwoofer size is dependent upon the space you have available for mounting. Some cars have plenty of space in the trunk which is the best option for custom audio installs.

Methods in which car enthusiasts are installing subwoofers into their cars is truly remarkable. Through various car shows, I have seen car audio enthusiasts removing their spare wheel compartment and installing large subwoofers.

The way in which you install your subwoofer is up to you but you will want to ensure that you take measurements before purchasing an expensive subwoofer.

Type of Enclosures

Some subwoofers will have an enclosure that’s mounted, which has a huge effect on the type of audio that will be derived from it. Generally speaking, sealed boxes will provide you with the deepest, most accurate acoustics compared with those that are ported in a bandpass enclosure. This will be able to be used to derive more volume.

If the space where you are installing the subwoofer is small, don’t try and squeeze a large 12 inch subwoofer into the space. This will compromise the performance and be hard to install correctly.


The power and sensitivity of the subwoofer work intricately with each other in order to deliver a high output. Subwoofers with a higher level of sensitivity will require less power to produce the same amount of quality sound as a subwoofer that has a lower sensitivity rate.

Subwoofer Power

When looking for the most powerful subwoofer, you will want to analyze the RMS rating as opposed to the peak power ratings. The RMS rating measures the continuous power handling or output. This is a significantly more realistic measure to determine the power supply compared to peak power.

Subwoofer Speaker Size

If your ultimate goal is to create a sound system that has the ability to play your music loud and at low frequencies, then you can simply go for the largest sized subwoofer.

However, just because a subwoofer may be small, it can still make enough power to match with the larger units. Technology is making electronics smaller and more powerful but this usually costs more.


Impedance can be defined as resistance to the flow of electricity, which changes depending upon the frequency the subwoofer is generating. The majority of subwoofers have an impedance rating of 4 ohms. However, those with measurements of 2-ohm, 8-ohm, as well as dual voice coil subwoofers are becoming more popular.

The majority of car amplifiers will require certain resistance to function to the best of it’s abilities. This is because as the subwoofer moves, so does the resistance values, which means mismatching amplifiers will cause performance issues to the sound quality.


Types of Subwoofers

To make choosing a subwoofer even more tasking, there are three main types of subwoofer to choose from. Each subwoofer type has their own Pro’s and Con’s and they are as followed.

Subwoofer Driver

This is the subwoofer unit that’s most popular and is often referred to as a passive subwoofer. They are mounted inside the enclosure of the subwoofer for them to operate properly. They require the power from an external amplifier, and can range from 8 inches to 15 inches in size.

Powered Subwoofer

These types are a combination of an amplifier and subwoofer situated within the enclosure. Powered subwoofers don’t require a lot of space in your vehicle but they have limitations with regards to the amount of bass they deliver.

Vehicle Specific Subwoofers

These types of subwoofers are specifically designed in order to fit in the small spaces of a compact size cars, trucks, and SUVs.

How to Match Subwoofers and Amplifiers

To get your subwoofer working to its optimal performance, you will need an amplifier. A subwoofers impedance is measured in ohms and an amplifier will output varying power dependent upon the impedance load of the subwoofer.

To get the perfect match you need to achieve the following:

  • Subwoofer OHMS that can handle the Amplifiers watts RMS
  • Amplifier Watts RMS into the Subwoofers OHMS.

You will also want to ensure that the amplifier you select is capable of supplying between 75% to 150% of the subwoofer’s total rating for the system. If possible, we advise matching the brand unless you need more power that the brand doesn’t offer.


Introducing a car subwoofer with hard hitting bass can make a huge difference to your car’s in-car audio experience. Many cars lack bass and this can be fairly frustrating if you like to listen to music with deep bass. Most car owners will install either a 10 or 12 inch subwoofer to their car but the placement differs depending on the space available.

Our car subwoofer recommendations cover everything from maximum power output, shallow mount and powered subwoofers. Therefore you should be able to find the best car subwoofer that fits your requirements.
