If you want to listen to great music in your car, you need a top-rated subwoofer. Car speakers have a difficult time producing low-frequency sounds because of their small size. Without these lower sounds, any type of music is not going to sound as good as it could otherwise. Even classical music has some pretty deep bass. The best, high-quality subwoofers are more than another speaker. They’re your ticket to deep, rich music on the go. To help you pick the best subwoofer for your car, we put together this complete buying guide complete with car subwoofer reviews.

Benefits of a Subwoofer for Car

  • Improve your car’s sound system. The main benefit of a subwoofer is its ability to produce low-frequency sounds. Your usual, small car speakers often have difficulty making these sounds. No matter what kind of music you listen to, choosing a top of the line subwoofer can take your listening experience up a notch. 
  • Take it anywhere. Unlike other additions to your car’s sound system, a subwoofer can go practically anywhere. You can put one in your trunk, under your seat, or even just in the back seat. They don’t have the same space constraints as other sound components. 

Types of Subwoofers for Cars

Component Subwoofers 

Component subwoofers only come with the speaker itself. All other components must be bought separately. This is good for those who want to personalize their subwoofer and build it from the ground up. Many component subwoofers vary quite a bit from model to model. You can pretty much find whatever you’re looking for in this category. You will need to choose and buy other equipment for them to work properly. 

Enclosed Subwoofer 

An enclosed car subwoofer is simply a speaker that comes already put into a box. With these subwoofers, you don’t have to worry about selecting an enclosure separately. But, you might find yourself with fewer options than if you had chosen to build your system from the ground up. You will also still need an external amplifier to power the whole thing. 

Active Subwoofers 

Also called powered subwoofers, these are just like enclosed subwoofers but with an amp built right into the box. These work wonderfully in tight spaces and don’t require any extra work on your part. They are also simpler and easier to install since everything you need is included in one piece. You don’t have to worry about installing an amplifier separately. However, they are usually smaller and more compact. This can make them unable to deliver high-quality sounds. These systems work best for those who just want an add on to their stereo or who don’t have enough room for a bigger system.

Subwoofer for Car Pricing

  • Under $100: These car subwoofers usually only include the speaker itself or produce low-quality sound. Typically, you aren’t going to find any high-quality subwoofers in this price range. 
  • $100 – $200: This is where most of the average subwoofers are. Many will come with an enclosure, but you can also find high-quality speakers at this price range without one. 
  • Over $200: Once you pass the $200 mark, you reach the zone of complete car subwoofer kits. Most of these kits come with everything you need to produce a high-quality bass in your car. If you aren’t looking to personalize your system and just want a kit already put together, expect to spend about this much money. 

Key Features


When it comes to subwoofers, size really does matter. The larger the car subwoofer, the deeper the bass it can create. A 10-inch subwoofer is not going to sound as good as a 12-inch subwoofer. Of course, when getting a subwoofer for your car, space constraints are important to consider as well. A subwoofer that can’t fit in your car isn’t going to do you much good. For best results, we recommend purchasing a car subwoofer that is as big as your car can handle. Be sure to take measurements before you go shopping. 

Root Mean Square Wattage

The watts RMS of a subwoofer describes how much power it can handle on a continuous basis. The more power a subwoofer can handle, the better quality sound it is going to produce. 

Sound Pressure Level 

The sound pressure level is how much power a subwoofer needs to produce a given volume. The higher the SPL number is, the less power that subwoofer needs. Those with a low SPL number need more power to produce loud sounds. 


The enclosure, or subwoofer box, is exactly what it sounds like: the box the subwoofer sits in. The design of the enclosure affects the final sound quality more than you probably think it does. If you want a bass that is exceptionally deep, you should buy a subwoofer with a sealed enclosure. These produce a very deep sound, don’t produce a huge amount of vibration, and are very accurate. 

Voice Coils

There are two main types of voice coils: single and dual. In most cases, a dual voice coil is a way to go. This type of voice coil increases the range of amplifiers you can buy and helps maximize the power from that amplifier. You’ll also have more choices later on if you decide to make changes to your system.

Other Considerations

  • Car Size: Subwoofers take up extra room in your car. Because of this, it is important to consider your car’s size when purchasing one. A huge subwoofer is going to be hard to put in a small car. We recommend taking measurements of the space where you plan on putting your subwoofer before you begin shopping. Don’t forget about the enclosure and amplifier as well. 
  • Placement: Some subwoofers only work when placed in certain locations. For example, some subwoofers must be placed in enclosed trunk space. Be sure to keep this in mind when shopping.

  • If you want to make the installation as easy as possible, we recommend choosing a powered subwoofer. With one of these, you won’t have to worry about installing an amplifier as well. 
  • If you’re looking for a very specific setup, we recommend choosing an amplifier, enclosure, and speaker separately. 
  • Make sure any amplifier you get is compatible with your subwoofer. 
  • Choose a place for your subwoofer and measure it before you start shopping. Then, you’ll know exactly how much room you have. 
  • Remember, if a subwoofer doesn’t come with an enclosure, you’ll still have to buy one. This can increase the price quite a bit. You’ll also need an amplifier to power the system. It is very difficult to find a complete system that produces quality sound at this price point. In general, you get what you pay for. 


Q: How much does it cost to put a subwoofer in your car?

A: You should plan on spending at least $200 on a high-quality, average-sized subwoofer. This includes the subwoofer enclosure, speaker, and amplifier. It is possible to find small, compact subwoofers for less. These will not sound as good as the larger subwoofers, though, but they often work better for smaller cars. Depending on what you’re looking for, you might have to spend more money on a subwoofer, especially if you want one with lots of power or a unique sound. 

Q: How do I upgrade my car audio?

A: One if the easiest and most straightforward ways to upgrade your car’s stereo is with a car subwoofer. Because car speakers are small, they have a hard time producing low-frequency sounds. A car subwoofer is designed to produce these sounds. Even if you don’t necessarily listen to music with a lot of bass, a subwoofer can help produce those low-frequency sounds your car is probably missing. 

Q: What subwoofer size should I get?

A: On average, bigger car subwoofers produce better sound. Of course, this isn’t always the case. The exact sound produced also depends a lot on the quality of the subwoofer enclosure. Still, it is usually a good idea to purchase as big of a car subwoofer as your car can handle. It is impossible for a small subwoofer with a quality enclosure to produce the same sound as a big car subwoofer with a quality subwoofer enclosure.
