Say goodbye to hollow, lifeless, distorted sound in your Jeep. The complete lack of tweeters along with built-to-cost midrange drivers (even in the Alpine system) leaves much to be desired in the Front SoundStage of our Jeeps. Presenting the world's only Jeep-specific 80mm 2-way component speaker system: 80mm aluminum midrange drivers featuring curvilinear cones + inverted santoprene surrounds for optimal acoustical dispersion and elegantly reimagined grilles with integrated 20mm ferrofluid-cooled silk dome tweeters introduce a refined aesthetic to the interior and a detailed nuance to the sound.
Your music comes to life atop the dash with a warm, expansive, balanced image that brings studio-quality fidelity to every adventure you embark upon. There's simply no easier or more effective way to transform the daily driving experience in your Jeep. Scroll down to submerse yourself in technical knowledge - or if you're ready to rock just select your Jeep, factory audio system, accent tweeter ring color, hit the gold button, and prepare to hear your music again for the first time.
Flawless acoustical reproduction. Unparalleled Aesthetic.

Dash speakers, done right.
No more "may not be compatible with" or "slight modification required". We engineered our midrange drivers from the ground up for a perfect fitment using only ultra-premium materials (6061 curvilinear aluminum cones, inverted santoprene surrounds, injection molded baskets) to ensure long-term performance. Whether you rock out to Steve Perry, Winwood, Wonder, or any other kind of Steve - you'll feel like you're sitting in the front row at the show.
Factory look, aftermarket performance.
Music without tweeters is like running stock tires with a lift. The bean counters back in '14 decided you didn't need them, but we know otherwise. These warm, vibrant, 20mm silk tweeters were designed to pair harmoniously with our midrange drivers. The challenge was creating an elegant mounting solution. Enter our reimagined grilles. Drawing inspiration from the polished rings surrounding the gauge cluster, the tweeters are housed in machined 6061 aluminum casings that integrate seamlessly for a factory fit and finish.

To get the best possible listening experience:
For optimal sound quality in any vehicle, we want to be directly connected to the source unit via either USB or USB-C. While Bluetooth streaming is convenient the dynamism simply isn’t there yet in most modern vehicles. Yes, your music will still sound amazing with our upgrade, but if you’re after peak performance you’ll want a direct physical connection to your device.
Part of the upgrade process in every audio environment is setting the tone controls (bass, treble, any sort of EQ or enhancement) to a flat level (in the middle if a visual representation is offered) and making sure that any Loudness controls are turned to OFF. Beyond that, if you’re using your phone to stream music via most of the popular platforms, you’ll want to go into the device’s main settings and turn any Equalization to OFF on both the native music player and then within the streaming platform you’re using to make sure no additional sonic manipulation is activated (bass boost, etc). This is most important as you listen at higher volume levels, as distortion is the enemy of sound quality.
Why we don't offer a rear speaker upgrade:
The most common question we get, by far, is “Why don’t you offer a speaker upgrade for the sound bar?” Well, here’s why: The speakers in the sound bar are obviously already behind us, and given the movement of sound through the cabin and that our ears are tuned to sounds in front us (hence a "front soundstage"), we see little if any reason (which is of course debatable, but after 20 years of designing loudspeakers as well as audio systems of all types we've developed a sense for what really works for most people) in spending money on speakers that aren't effectively improving the actual presence of a soundstage in front of us (think of a band at a concert).
We spent the better part of 18 months dialing in this upgrade, and after extensive modeling and actual prototypes installed in the rear sound bar we just don't see (or hear) a valid reason to add speakers/spend money on speakers behind you. Sure, you can "hear" some additional sound coming from behind you but your ears/brain can't process it in such a way that you'll perceive any improvement in what you're actually hearing. We could’ve easily “designed” some rear speakers (hell, the midrange drivers are identical) and sold it as an upgrade but we’re tired of companies always preaching “more, more, more” when it doesn’t truly benefit the customer.
Measure twice, cut once.

- 80mm midrange driver
- 20mm tweeter
- 6db first order high pass filter on tweeter
- Frequency Response 100Hz-22kHz
- Nominal Impedance - 7 ohms
- Power Handling - 35 watts per channel at 8 ohms
For those of you with aftermarket amplification - For optimal performance, you'll want to select the Alpine version of the speakers as there are no additional filters on the midrange driver itself. Here's how to tune your amplifier for optimal staging and acoustical performance.
- Set the head unit volume to approximately 90% of it's output volume (numerically speaking, if your head unit max volume is at 50, turn the head unit volume to 45.)
- Before tuning the amplifier, turn all output channels (gains) all the way down so you're able to dial in the front output of the Terra Acoustics components.
- On your channels that power the Terra Acoustics components, set your amplifier's output filter to High Pass and adjust the frequency to approximately 180Hz.
- Slowly increase the gain on the channels of the amplifier that power the Terra Acoustics components until you hear them playing as loud as you'll be listening to the music. KEEP YOUR EARS OPEN FOR DISTORTION. While these drivers are capable of very high outputs, since amplifier power and output varies you'll ultimately be responsible for determining the maximum capabilities of the system.
- From there, blend in the remaining channels of the system to bring a balanced listening environment to the Jeep.
- Allow 3 or so hours for the components to properly break in before putting the system through its paces. The glues and materials need to acclimate to the inevitable rock concert that will soon follow.

Alpine vs. Non-Alpine
How can I tell the difference?
Not sure if your Wrangler or Gladiator has the Alpine upgrade from the factory? The easiest way to check is by identifying if a factory subwoofer is present. Use the image and description below that corresponds with your vehicle. If the factory subwoofer is present, order our Alpine System upgrade. If no subwoofer is present, you order our Standard System upgrade.
2018+ Jeep Wrangler 4-Door
4-door Wranglers equipped with the factory Alpine System will have an Alpine subwoofer in the rear storage area (trunk) along the passenger side wall.
2018+ Jeep Wrangler 2-Door
2-door Wranglers equipped with the factory Alpine System will have an Alpine subwoofer in the floor of the rear storage area (trunk).
2020+ Jeep Gladiator
Gladiators equipped with the factory Alpine System will have an Alpine subwoofer behind the rear seat, as shown above.
