Car speakers are a hot topic in the automotive audio community.

The thrill of riding around town and listening to your favorite songs is unbeatable.

The most common problem with factory-installed car speakers is that they either do not last long or sound poorly.

A speaker should be capable of delivering more than just audio. According to you, what is the best car speaker you can buy?

There doesn’t seem to be a hard or universal answer to that question since it would depend largely on your own individual preferences.

JBL and JL audio devices are both high-end brands. Today, you’ll get a detailed review of both companies. So, let’s get straight to the point.

JBL Audio

Harman International, which itself is now a part of Samsung, owns JBL. Speakers and electronics from JBL are available for residential, commercial, and professional use.

While JBL and JL Audio claim to manufacture for the prosumer market, JBL is an internationally recognized brand, while JL Audio focuses solely on the US market.

The company specializes in large PA systems but has also developed speakers for car audio – initially subwoofers, then smaller speakers and components. In addition to consumer audio products, they also manufacture some professional products.

A major component of JBL’s business is creating, recording, and performing at the world’s top venues. A studio (where music is created and accuracy is paramount) and an IMAX theater (where clear, loud sound is impressive). Everything from main concerts to Oscars and Grammys. 

Defining how music should sound is JBL’s specialty. It would be impossible to separate Woodstock, Beatles Abbey Road studios & JBL if you want a piece of history.

They are the largest Speaker company in the world for a reason. Almost every Ferrari car comes with a JBL sound system. It’s there if you want to know.

Those who are looking for exotic speakers at the top of the chain (and very expensive) will find the JBL Everest Speakers and K2 Lines impressive.

JBL produced some genius products, but there were also some absolute garbage products. The sound quality of high-end professional speakers is generally excellent. There is a wide range of quality when it comes to low-end consumer goods.

Benefits of JBL Car Speakers

The outstanding value for the price is one of the major advantages of JBL car speakers. Most of the JBL products are affordable and available to the average consumer. A big difference is that the quality does not suffer due to this affordability.

According to reviews and tests, even the least expensive JBL car audio equipment lines perform well. Low cost and high quality make JBL car speakers a great choice.

The sound quality and performance of JBL car speakers are outstanding. They provide thumping bass and excellent balance. No matter what genre of music you listen to, this quality remains the same.

You will be able to hear great audio no matter what you listen to, be it classical or rap music. Good car audio relies heavily on sound quality, and JBL car speakers provide exceptional sound quality.

JBL car speakers are also easy to install. Make sure to check whether or not your car requires mounting brackets before purchasing JBL car speakers.

If you purchase your car audio from a retailer, they should be able to order them for you. You can save a large amount of money by installing JBL equipment yourself and increasing its value.

Drawbacks of JBL Car Speakers

Despite their excellent performance, JBL car speakers have one drawback: their look. According to some, the grill design looks dated and needs to be updated. For those looking for a custom look without much effort, this can be a drawback. An older look can lead to a purchaser spending more to customize the speakers. This may be a drawback if the overall appearance of the car’s audio equipment is important to you.

Additionally, JBL car speakers are more expensive. The JBL line can seem expensive compared to JL Audio and Polk audio. The cost of JBL, however, makes sense when compared to its quality and durability. Purchasing JBL car speakers can be expensive at first.

Before purchasing car audio equipment, comparing the benefits and drawbacks is important. JBL car speakers offer far more benefits than drawbacks, making them an excellent choice for car audio.

Recommended JBL Subwoofers

JBL GTO629 Premium Coaxial

Known for years for their home audio products, JBL’s GTO629 Premium Coaxial speakers prove they’re equally capable of competing in the automotive space. 

Their combined dual output is 180 watts, plus they use the brand’s patented Plus One woofer cone, which effectively increases output. A plus-one woofer technology and crossover filters are included. The downside is that they’re still a bit expensive despite being a mid-range pick.

JBL GTO609C Car Speaker System

There is nothing better than the JBL GTO609C when it comes to a complete component speaker set for cars. This speaker produces a wide spectrum of frequencies – crystal clear highs, sharp midranges, and punchy bass. They will not disappoint you as they will be the perfect replacement speakers for your OEM car speakers.

The speakers have a 3-ohm impedance rating, which is really low. By doing this, you can make the most of the watts that your car stereo system is capable of delivering, despite the undersized wires commonly found in many cars.

We recommend amplifying these speakers if you would like greater sound quality and louder volume.

The sound quality of these speakers is excellent.

The JBL GTO609Cs provide some of the best sound quality and volume we’ve ever heard in a car audio system. They are a good pick for cars requiring more volume and bass.

JL Audio Company

The company’s name is derived from the first initials of its founders, James Birch and Lucio Proni, who founded JL Audio in 1975.

It started out as a home speaker system kit maker but eventually evolved into one of the leading high-end car audio companies.

Throughout the history of high-end car audio equipment, they have been known for their subwoofers that produce deep bass.

As a part of the company’s expansion, Birch and Proni opened a retail store called Speaker Warehouse with Stephen Seidl, a third partner.

In addition to maintaining their JL Audio empire, Birch and Pironi’s innovative car audio technology helped the company flourish under Seidl’s management.

Even today, their subwoofers remain some of the best in the industry and top performers.

While some may perceive these subwoofers as “too expensive,” JL Audio subwoofers never fail to meet the company’s commitment to making top-quality subwoofers.

This small company produces speaker systems for automotive and marine applications as well as high-performance powered subwoofers.

Frequently Asked Questions (FAQs)

Is JL Audio the best car audio brand?

JL Audio is a trusted and well-known brand in the world of car audio. It produces high-quality, long-lasting products. Audiophile enthusiasts love their products because they deliver accurate sound reproduction, making them ideal for improving their car audio system’s sound quality.

What does JL Audio stand for?

James Birch and Lucio Proni founded JL Audio in 1975. In order to form a name for their company, they used the first letter from each of their names, so “JL” became their company name. Their first products included home speaker systems, along with home speaker kits.


When it comes to replacing your car’s speakers, there are many factors to consider, but the size is one of the most important. Getting larger speakers than factory ones is possible, but it will cost a lot of money for your installation team or work on your part if you plan to install them yourself.

The next step is to consider whether you will replace your head unit. Regardless of which speakers you choose, you must ensure that the head unit can power them. Otherwise, an amplifier may be needed.

The final step is to decide whether you will be running a coaxial or component setup. The sound quality of component setups is generally better, but they are also more expensive to purchase and more difficult to install.

It is important to remember that simply replacing your car’s speakers won’t make it a concert on wheels. Even if you’re looking to improve your sound quality, you’re better off upgrading your entire sound system if you want to turn heads.

Both the JBL and JL audio companies are good and have something for everyone. You can choose any brand considering the above points. Because, in the end, the decision is based on your personal needs and preferences.
