The best car subwoofer is much more than just a trunk speaker. The best sound from a subwoofer is based on the balance of power, quality and performance.

1. Rockford Fosgate P300

In its most basic form, a subwoofer is a low-frequency speaker. To get the sound to the subwoofer, you’ll need to send some power to it, unless it comes with a built-in amplifier like the Rockford Fosgate P300 and other models included in this article. The P300 comes in a sealed box, for tight, accurate bass sound.

The built-in 300-Watt amplifier means all you have to do is plug in the power and a sound source and you’re good to go.

The case of this subwoofer is perfect to install under the seats of a truck, or even in small trunks. The cabinet is made of MDF and covered with heat activated industrial vinyl. In addition to being a solidly built all-in-one bass solution, the P300 also has a variety of features to help improve the sound of your car.

2. RockSeries RKS-12D4XS / D2XS / D1XS

All-in-one powered subwoofers excel in convenience, but often lack power. If you want to feel the bass in your bones and wake up the neighbors a few blocks away, you need a product that is completely on another level.

The RKS-12D4XS subwoofers are a product for the SPL and Open Show enthusiast as they easily support 1,500 Watts RMS. You will need a separate speaker box and you will need to power them with a very powerful Class D amplifier; We recommend a 2,000 Watt one. Once configured and connected, this subwoofer can be your own seismic machine. Unless you are an expert in car audio, do not try to install this beast on your own, otherwise you run the risk of Voltage drop. But if you’re looking to win a competition, RockSeries subwoofers may be your ticket. The RKS-12D4XS is a monster that will take your car audio to depths without imagining. You have to be quite serious about using it, as it may be too much for most people.

Great for anyone wanting to enter a car audio competition, but for casual listeners and enthusiasts, it can be overkill. Step lightly and make sure you know what you’re getting into, make sure a qualified professional installs it.

3. MTX Audio Terminator Series TNE212D

Some subwoofer units include speakers and a box, but require separate amplification. As you move down the food chain from all-in-one units, you may want to use a separate amp to dial in your ideal sound. In such a case, the MTX Terminator is a sealed speaker and speaker combo that can handle a ton of power. Each speaker measures 12 inches and is made with a polypropylene cone, with a maximum power of 1200 Watts and a power of 800 Watts RMS.

It will look good in your trunk, but be careful as you could cause that trunk to break into pieces. Like a sealed speaker unit, the sound is deep but not too “boomy”. As with any single speaker setup, the amplifier that matches the subwoofer will be key to your sound.

Another great bass shot, but more restricted than the RockSeries, the Terminator MTX is a great fit for those who want a traditional trunk box design.

4. Treo79SS

The Treo79SS offers the low sound frequencies that will keep your music at full volume.

Like a slim subwoofer, the Treo79SS is designed to slip under a car seat, like the front passenger side. Since it’s only 2.7 inches thick, it will fit almost anywhere. With a built-in 220-Watt RMS amplifier, you can be sure that low frequencies will be present inside your car. Treo has simplified the installation even more, so all you need to do is connect the high input to one of your car’s existing speakers or via RCA, the unit includes signal detection for automatic operation when it detects signal audio.

It is a simple option for those who are space conscious, but it is not for you if you are looking to win a competition against a large box in the trunk. It includes a remote control that adjusts the volume of the low frequencies.

5. JBL GT-BassPro12

It offers all the bells and whistles of an all-in-one subwoofer in a rugged design. With an exposed subwoofer and oversized, industrial-style roll bars, this JBL screams to show off on your ride. The bars are clearly attractive, but they are also quite functional.

The open design and ventilated pole piece keep the motorized speaker motor cool, improving performance and reducing distortion even at the highest levels. Installation is easy, and the unit includes signal detection for automatic operation when it detects an audio signal.

It is not the cheapest option on the market, but it is reasonably priced for its features and performance.

6. AudioLabs ADL-SAS68

Like the Rockford model, the AudioLabs ADL-SAS68 is intended for consumers who want to add a little bass without sacrificing all interior and storage space. Although it does add some bass, don’t expect this model to break windows or twist enough to soak up your bones with low frequencies. The built-in amplifier only has a nominal power of 150 Watts but for the vast majority it will be enough.

The AudioLabs ADL-SAS68 shines, however, as a stylish addition to an existing audio system. Like most all-in-one units, installation is easy. AudioLabs also provides a remote control, so adjustments can be made on the fly.

AudioLabs is clearly marketing this product to those who want a quick and easy way to accentuate their existing audio system.

7. Rockford-Fosgate PS-8

 One of the concerns of powered subwoofers is how they take advantage of your car’s electrical system. Some can be connected directly to the battery, while others connect to any of the different power sources in your car. Sometimes either option means you may have a device that is drawing power and is draining the battery or affecting the performance of other systems. Nicknamed the “Punch Single 8”, this is a fully enclosed small subwoofer. It has a 150-Watt Class D amplifier and an 8” subwoofer. As an all-inclusive subwoofer system, all you have to do is connect it to a power source, connect the unit’s ground, and take advantage of an audio signal, and you’ll add some bass depth to your sound system. It is well built and a good choice for those looking to save space, but the small speaker greatly reduces the effect of the bass.

8. Kicker 10TC 104

Let’s say you want a solid subwoofer in a carpeted cabinet that you can match with an amp, but you don’t have room for a giant three cubic foot speaker in your trunk. An enclosure like this is just what you need. Kicker makes well-regarded products, and the 10TC104 lets you add power without sacrificing space. It has a nominal capacity of up to 300 Watts, so be sure to connect it to amplifiers in the range of 300 to 500 Watts RMS. It has a sloping enclosure, approximately 8 “deep at the base and 3.5” deep at the top. It is constructed of .75-inch MDF and is wrapped in rugged rug.

Its high-performance construction ensures it is durable, as long as you pair it with the right amp. Best of all, this unit is fairly easy to install if you have a little car audio experience. Fits perfectly in a pickup truck cab.

9. Polk Audio db1040

If you have a cabinet and just want to add a little performance, using a low-end subwoofer, the Polk Audio db1040 may be a good choice.

This speaker is simple but is designed to withstand the harshest conditions. Ideal for marine applications, but also works well if you’re concerned about moisture.

With this Polk speaker, you can expect deep, precise, and choppy bass. Polk Audio makes some of the best audio components on the market, and the db1040 is no exception. User reviews compare sound to a club-like experience. The sound rumbles, but the clarity and sharpness of other tones are not lost. Combine it with a sealed loudspeaker and you will get high quality bass without distortion.

The marine rating on the db1040 means that your boat can also have good bass, or if you need a waterproof solution for the top of your jeep, durability won’t disappoint. Excellent sound and responsiveness.

10. JL Audio 12W7AE-3

 If you’ve made the jump to high-end car audio, you may be wondering where you can find the apex of bass sound. JL Audio’s 12-inch subwoofer may be the pinnacle of the boom. You can look at it and comment, “It’s just a speaker,” but this seemingly simple element is the key to low frequency. Entry to this sacred sound is not cheap, and you’d better make sure you have the proper setup to take advantage of all the brash, pulsing rhythm that this beast can press.

Let’s get the scary part out of the way first. The JL Audio 12W7AE-3 is incredibly expensive. It has a maximum power of 2,000 Watts, but the optimal range is 400 to 1,000 Watts RMS. It has a solid cast alloy basket, making it a 12kg heavy speaker. This speaker is considered to be the best car subwoofer on the market.

The JL 12W7AE is a good case for quality over quantity. Many reviews from other subwoofers talk about how many years (or months) it was before the subwoofers had to be replaced. With the JL, you pay a lot in advance, but you probably never need to buy a replacement. With its luxurious construction, this speaker exudes a high-level feel as it is made of the highest quality materials.
