Most consumers are not fanatics. This means that you’re probably looking for a product that gets you by with value, quality, and performance. You may not necessarily require your product to be the best of the best or the highest performing one on the market. If you’re a car audio fan but not necessarily an enthusiast, you probably want a subwoofer that could produce bass, enough to make your car rumble or enhance the deep low level frequencies of your sound system.
If this is you, then the JL Audio 8W0-4 is your subwoofer of choice. It’s an 8″ subwoofer that packs quite a punch. It is capable of putting out 150 watts of maximum power and 75 watts of RMS continuous power. At first sight, the 8″ may not be the most intimidating subwoofer cosmetically, however, it could indeed produce excellent quality bass outputs thanks to its design.
The woofer is composed of a polypropylene cone with a sealed polypropylene dust cap, a standard car subwoofer and speaker cone composition that ensures rigidity as well as consistency in any ambient environment. The cone is surrounded by a large foam edge that allows the subwoofer to maintain excellent centering while performing at high excursions. Underneath the cone lies the wide progressive roll flat spider that allows the 8W0-4 to ensure a superior mechanical control and placement.
For structural integrity support, the JL Audio 8W0-4 features a vented reinforcement collar, or VRC which acts like a pillar under a bridge acting as support while absorbing performance-related energy. The last feature that must be pointed out is the 6-layer voice coil wiring on a former that is known in the car industry world as Kapton. The result of this feature is the ability for the subwoofer to handle massive thermal energy without losing performance or damaging itself during the energy transfer.
Another nice thing about the 8W0-4 is the fact that its compact size does not typically require a sealed box volume larger than 0.375 cubic feet or a ported box volume larger than 0.75 cubic feet. This means that the JL Car Audio8W0-4 is excellent for small space installations like compact cars or hatchbacks.
With features like this and its incredibly affordable low price at less than $40, how could any car audio beginners pass up a car subwoofer deal like this?
This will be my first product review. This is my first hands-on test with Massive Audio speakers and they are installed in my personal vehicle, not in a demo board. The car has no extra sound dampening and the only other upgrade is an Alpine CD player. On with the review.

What you get in the box is an instruction manual, warranty registration card, a pack of screws and matching sheet metal clips, speaker grills, and the speakers themselves. The grills look classy and complement the stylish smooth dark looks of the speakers. A couple of notes about the speaker design. As the title of this article states, these are slim speakers. At just 1.6″ inches they can fit in any door, which seems to be necessary for some European cars. For comparison this is hardly thicker than your closed laptop computer. Another notable design highlight is the “point source” driver configuration. This is evident in the placement of the tweeter flush with the center of the woofer cone. The benefit of this is the midrange and treble notes start on the same linear plane, meaning there is no delay like you normally get in coaxial speakers. It’s not something an ordinary listener is ever going to notice compared to a traditional post mounted tweeter, but it shows Massive Audio’s focus on serious sound quality at an affordable price.
These speakers are CEA Certified, meaning you can compare these head-to-head with other CEA certified speakers for their rated thermal power handling. I have them powered by one of the older Alpine V-Power head units, which has an extra beefy internal amplifier rated at 27 W x 4 RMS. It’s plenty of juice to get the SX6 cones thumping hard. I would imagine these would do quite well on a 50×2 amplifier.
I have only about one hour of listening time with these little beauties, but I’ve been very impressed. The tweeters are exceptionally musical and detailed for a low cost speaker. I have had them playing right in front of my face, which normally is a bad idea as most tweeters I’ve heard are not the most pleasant on axis. I’ve not yet found any music that causes these speakers to feel fatiguing at high volume. I was very pleased to find I could distinctly hear different cymbals in a loud passage of an Anberlin track off their latest album. The new level of detail is exactly what I wanted and these speakers deliver detail in spades. The midrange performance is also excellent. They can dig deep with synthesized instruments, as heard on Radiohead’s Kid A. On a very percussion heavy album, The Hammering Process by Living Sacrifice, featuring two drummers, every instrument was distinct.
I do have plans to replace these speakers and move them to the rear deck, but they definitely will have a place in my car for a long time to come. They sell for $99.95. I will conclude this review with a list of pros and cons.
- Great size, slim enough to fit any application
- Amazing clarity for the money
- Attractive – too bad they’re usually hidden behind a panel
- No wire leads included
- More affected by legs blocking sound than the factory speakers
For some, a factory-built car stereo is just not enough to fulfill their pleasure of music entertainment on the road; therefore, some adhere to upgrade the piece with extra amplifier. Just like its name, a car audio amplifier will magnify low level signal from its source unit and change it into a high level signal for driving the loudspeakers. Thus more quality will be brought.
