Few folks spare a thought for his or her in-car audio techniques. Whether or not it is the anonymous setup in your base Toyota Corolla or the theatrical, motorized-tweeter association in your Lamborghini Urus—audio techniques are sometimes taken with no consideration, besides by those that really get pleasure from listening to music.
Behind that invisible dependability is one enormous firm making practically all of it: Harman Worldwide. Harman owns Bowers and Wilkins, Infinity, Mark Levinson, Lexicon, Polk, AKG, Harman/Kardon, and JBL, with a couple of extra sprinkled in for good measure. It’s fairly the formidable lineup.
In sensible phrases, Harman makes virtually 50 % of all in-car audio techniques. In america, it’s extra probably than not that your automobile has audio system, an amp, and a head unit made by one in all many corporations in Harman’s nebula of audio manufacturers.
We needed to see the place all of it comes from. So we took a visit to Harman’s Northridge headquarters—which additionally occurs to be JBL’s foremost campus—to see a little bit little bit of the behemoth behind a lot of automobile audio.

The Firm Behind In-Automotive Audio
Within the San Fernando Valley north of Los Angeles correct, JBL’s outdated manufacturing middle nonetheless exists. Solely now it’s a mix of the Harman Expertise Middle, the place company can witness the breadth of product on provide, and a company campus that homes one in all JBL’s analysis and growth groups.
Oddly, it’s not likely the house of automotive growth, but it surely does make one thing abundantly clear concerning the audio behemoth: It doesn’t simply make most automobile stereos. It makes practically the whole lot.

The expertise was centered largely on JBL, which most individuals will know for both its Flip collection of Bluetooth audio system or because the premium stereo possibility for contemporary Toyota merchandise. JBL can be nonetheless deeply concerned throughout all ranges of the audio market, and regardless of being a part of the bigger Harman conglomerate, it retains its personal R&D workers and services.
JBL’s roots lie in skilled audio; the stuff utilized in music studios, live performance phases, and film theaters. The core enterprise nonetheless exists, with JBL making enormous loudspeakers for live shows, innovating spatial audio experiences for consumer-grade stuff, and in addition holding sturdy on skilled studio displays.
All of that have, the corporate says, results in automotive growth. A lot of Harman’s experience in live performance audio and audio imaging appears to come back from JBL.
How Your Automotive’s Audio System Is Made
It wouldn’t seem to be it, however all of these abilities trickle into Harman’s automotive aspect. It’s an enormous firm, to make sure, and I don’t assume it’s as clear as “professional audio leads instantly into automotive,” however classes will be realized. The reality is that automotive audio is exponentially trickier than the conventional stuff.
When requested about automotive, a JBL consultant mentioned, “It’s the toughest a part of the enterprise. Not solely are value targets extremely tight, however so are weight and sturdiness necessities.” He paused, then added, “It’d be a nightmare if the problem wasn’t so participating.”
Vehicles are presumably the roughest atmosphere for a delicate digital speaker. Not solely do automobiles vibrate, however in addition they sit within the solar, must survive scorching triple-digit temperatures, work in sub-zero situations, and take care of all of the conditions your common day by day drive creates. Hell, automotive audio system could even must be spill-resistant.
‘It’s the toughest a part of the enterprise. Not solely are value targets extremely tight, however so are weight and sturdiness necessities.’
The acoustics of a automobile are additionally extremely advanced and much from best. In the event you have a look at pro-level studios, each floor is fastidiously angled or sound-insulated to offer an ideal tone the place the audio engineer will sit. A automobile has extremely reflective glass surfaces, countless aspects and folds, and in addition has to deal with highway noise and engine noise.
A lot of that problem is overcome utilizing imaging methods and lively noise cancellation. JBL (and all different automotive audio corporations) fashions the within of the automobile and instances every speaker’s output right down to the hundredths of a second in order that the audio reaches the motive force’s ear cleanly.
Despite the fact that automobiles throughout a number of fashions use the identical audio system, amplifiers, and head models, they’ll all sound extraordinarily completely different based mostly on whether or not the automobile has leather-based or material seats, a distinct headliner materials, or a panoramic sunroof. In a really perfect world, each automobile is tuned to those trivia, and Toyota’s JBL purposes usually are.
That mentioned, a JBL setup nonetheless isn’t as much as the usual (or value) of a Bang & Olufsen stereo—so it’s not absolutely the benchmark. In spite of everything, it’s for a Toyota, not a Bentley. However the mission, regardless, is to offer good audio for the worth level, which JBL does, even when it doesn’t knock your socks off.

Secure And Sound
I had the possibility to strive a Toyota GR Corolla and a Toyota Land Cruiser with JBL techniques. The GR Corolla lacked bass however had total readability, whereas the far more costly Land Cruiser had a fuller, richer sound profile. Within the higher-end stuff, just like the Mark Levinson system that lives in Lexus automobiles, you get knock-your-socks-off audio. As ever, you gotta pay to play.
Level being, the trouble that goes into even probably the most fundamental audio is immense. Getting good audio is dear, and getting distinctive audio is usually the worth of an financial system automobile. And it’s not at all times in higher {hardware}, however typically in higher software program.
So, sure, you’ll be able to toss an enormous subwoofer and a system in a automobile to make it loud. However making the audio have good constancy, a wonderful tonal response? That takes the experience and engineering that only a few can present.
