Message from Founder of NVX

"I felt that I needed to own a vehicle that embodies technology and represents forward thinking.  The Tesla Model S satisfies those aspects and so far has brought me great pleasure. Being the owner and founder of NVX, it was absolutely imperative that my vehicle have additional bass to further the premium sound.  With this premise I challenged our engineers and technicians to devise a subwoofer upgrade for my Model S that did not sacrifice space. At this point, we feel that we have created the best solution to satisfy any Model S owner's desire for a more premium sound." - Nathaniel J Victor, Founder NVX

An amazing car deserves an equally amazing sound system, and the Tesla Model S is certainly no exception.  That's why NVX has developed the NVX B.O.O.S.T Series Bass Package. This Tesla-specific audio enhancement features a powerful 10" VC series subwoofer in an enclosure designed exclusively for the Model S, a BDA7501 monoblock amplifier, a XKIT42 amp kit and an Audio Control LC2i premium line-out converter to bring your system to life. Don’t leave yourself with only the factory 'standard' or 'premium' sound systems when you can improve the sound with this package.




Loaded Enclosure

Painstakingly designed by the in-house engineers at NVX, the loaded enclosure is made from hand-laid fiberglass to create a lightweight, durable enclosure that corresponds beautifully to the driver-side trunk recess in your Model S. It also features a Terminal Cup with spring loaded, chrome-plated binding posts for optimal connection and ease of installation. Built-in to the enclosure is the NVX high-technology VCW 104 subwoofer driver. The B.O.O.S.T. bass enclosure tucks into the driver-side trunk recess without taking up valuable cargo space. The VCW 104's long excursion capability and power handling allow it to deliver acoustically accurate and extended low frequency output at any listening level.

XKIT42: 4 Gauge Amplifier Kit With 2-Channel RCA

Everyone needs a good sidekick, and your amplifier is no exception. To give your amplifier the power and support it needs, three goals remain paramount – durability, usability, and performance. To achieve these goals, the NVX B.O.O.S.T Series Bass Package uses:

Tough, Rugged Wire
 - NVX amp kits are built using materials that are not only of the highest quality, but also specifically engineered to provide optimal performance in the harsh vehicle environment. The durable EnvyFlex jacket offers superior flexibility and routing options, all while keeping the wire properly insulated. For added protection against chafing, the wire is terminated with 6 feet of nylon braided jacketing. 

Maximum Power Transfer
 - The power and ground wire in your NVX amp kit is constructed with Silver-Tinned 100% Oxygen-Free Copper. By using these pure, highly conductive materials, we ensure that our amp kits can transfer massive amounts of power from the battery to your amplifier without overheating. 

Solid Connections 
- The fuse holder and distribution blocks are made of satin chrome-plated brass, which easily tolerates the heat and vibration in the engine bay without corroding. The wires are held tightly by strong hex-head set screws, while durable ABS cover insulates the terminals and prevents short-circuits. All spade terminals and set screws are nickel-plated for maximum power transfer.

NVX was founded in 2011 by a team of industry veterans with decades of collective experience in engineering, product research and development, retail sales and distribution. NVX has a unique combination of vision, passion and experience that sets it apart from the competition, as it is not driven by profits and countless models, but rather by a desire to educate the consumer about quality audio and our commitment to innovation. Every product produced by NVX undergoes an arduous engineering and testing process with a complete devotion to quality throughout the entire process. NVX adheres to strict attention to detail and stringent quality control measures to ensure that its products always meet or exceed listed specifications. 




"In evaluating vendors, we liked NVX’s amps as they are some of the smallest, highly efficient class D amplifiers available.  It also helps that NVX understand the Model S, as the company’s president also has a Model S as I discovered after selecting the NVX amplifier. The audio clearly sounds better with a full deep range that you hear parts of music that I never heard in the car before. A regular passenger when [she] heard it for the first time commented 'This is 100% better', and she’s a drummer!  Now this seems a bit extreme... but I can agree it is better and worth the effort." - Frank van Gilluwe, Teslatap

 NVX Wiring Diagram




Is this a DIY project? Can I do this myself?   

This is a complex install that requires audio installation experience and a strong knowledge of the component types and wiring requirements. For that reason, professional installation is required in order to eliminate wiring and/or installation errors.

Where can I find a professional installer?

There are many competent aftermarket car audio installation locations in your locale. It may be helpful to locate a professional installer who has had experience with the Tesla Model S and comes recommended by others. We've created extensive installation materials (including a detailed installation video, see 'Video' tab) in order to assist a professional installer with guidance as he/she installs on the NVX B.O.O.S.T Series Bass Package.

How long will it take my professional installer to install the NVX B.O.O.S.T Series Bass Package?

If you check our 'Video" tab, the professional installers who demo the install note that it should likely take between 5 - 6 hours, possibly less if the installers have significant experience working on Teslas.

How much should professional installation cost?

We suggest you get an upfront quote from your professional installer, but, typically prices can range from $60/hr. - $150/hr. depending on your location. As we noted earlier, professional installers estimate the install should take between 5 - 6 hours, possibly less if the installers have significant experience working on Teslas.

Where should my professional installer mount and connect the amplifier?   

Please refer to the detailed instructions in your shipment and installation video (see 'Video' tab). The amp can be mounted in a number of locations. We suggest installing the amplifier in a concealed location within the frunk as shown in the video.

Can I buy individual parts from the NVX B.O.O.S.T Series Bass Package? That is, can I purchase one or two items "piecemeal" as opposed to the whole package?

No, NVX has custom-designed the package to be fully integrated (as described, see 'Overview' tab) for the highest quality, most seamless installation, and best sound system upgrade experience for Tesla Model S owners. Therefore, we do not recommend "swapping out" parts, or, buying individual parts (within this package) as it will likely take away from the high standards of quality designed into this integrated package.

Can this be removed if I sell or terminate my lease?   

The effort required to remove remove the enclosure and amplifier. However, wiring is somewhat more complex and is best performed by a professional installer.

Do I have to modify the vehicle in any way to install this product?   

No, the only thing required would be to drill a few holes to mount the amplifier and one hole to mount the enclosure, all of which are concealed.

Does the NVX B.O.O.S.T Series Bass Package come with a protective speaker grille cover?

Yes the NVX B.O.O.S.T Series Bass Package comes with speaker grille cover. Earlier versions of the product did not have this (which is why some of the photos on the product page don't include the speaker grille cover), however, all new orders include the speaker grille cover. See photo below for reference.

Is the NVX B.O.O.S.T Series Bass Package compatible with RWD and AWD ("D" dual motor) configurations of the Model S?

Yes! Please see 'Install' tab for professional installation videos for both RWD and AWD ("D" dual motor) configurations of the Model S.

Does the NVX B.O.O.S.T Series Bass Package work with both the factory 'Standard' and 'Premium' sound systems?

Yes. The NVX B.O.O.S.T Series Bass Package complements both factory sound systems with richer, deeper bass to enhance your listening pleasure. Please see the 'Install' tab for professional installation videos that review installation differences based on the factory 'Standard' and 'Premium' sound systems.

But, the Tesla Model S volume goes to "11" -- isn't the factory system already up to par?

The Tesla Model S factory sound system is a fine implementation, but, for those Model S owners who want an "upgrade" for richer,  deeper sound, this is a custom, all-in solution to enhance sound quality and achieve deeper bass for in-car music enjoyment.

Can't I just go to an car audio aftermarket shop and have them build a system like this?

You may, but, this system was specifically created, engineered, tested, and appointed for the Tesla Model S vehicle. NVX wanted to create a system that would enhance and complement the unique configuration/set-up inside the Model S. Furthermore, NVX worked hard to create a system that would have a competitive price-point that (in many cases) will outperform competitive systems at a significantly lower price.

What is the warranty?   

NVX offers a full one year warranty on all materials in the kit (see 'Warranty" tab at right).

How do you package the shipment?

Oftentimes, the NVX B.O.O.S.T Series Bass Package will ship in multiple boxes and you may receive one box ahead of another.

How long does it take to receive my order?  

The EVANNEX NVX B.O.O.S.T usually ships within 24 business hours of receipt of order. Delivery time depends on your location relative to South Florida and is typically within three (3) days for the continental U.S.

Does the NVX B.O.O.S.T Series Bass Package ship to international destinations?

As seen in Teslarati

Review excerpts and photos courtesy of Teslarati.


 "This little beast adds a tremendous boost to the Tesla’s already ‘premium’ but bass deficient stereo system."


First Impression

The sub woofer enclosure was wrapped in poly sheeting and wedged tightly in more of the packing foam. Its position low within the package gave the whole box a very stable stance.

With everything out the wraps it looked and felt like some pretty good quality stuff. This speaker box is topped with a sturdy steel grill in place to protect the speaker from any sort of external damage, and it seems like it could withstand some serious abuse. I considered building my own speaker box to fit in the foot well area but this NVX enclosure is a superb solution. Larger items can still be stored under the rear floor space since the speaker box fits snug into the little storage space in left side of the trunk.

The amplifier’s appearance is rather typical but the power output is impressive for such a compact unit. It displays an NVX logo that glows blue when powered and is supplied with a remote switch so you can adjust the bass while sitting in the drivers seat. There’s not much to the LC2i but one thing stands out to me. I have heard many complaints about the weakness of the rear sound or ‘forward sound stage’ in the Model S stereo. Looking at the LC2i it seems that you could really change the sound dynamics of the Tesla by using the other output to power a 2 channel amp and add some wide range speakers to the rear.

The Subwoofer


The NVX dual voice coil VCW104 Subwoofer fills the enclosure well. Housing a 2-1/2″ aluminum voice coil rated for 750 watts, the 10 inch speaker is capped with a woven fiber pressed paper cone to push the air. The magnet is chunky weighing almost 8 pounds!

Examining the rear of the speaker we see two sets of 4 ohm wire posts connected in parallel to match the output of the amplifier’s 2 ohms. The speaker is constructed very well and compares favorably to other drivers within a similar price range and power output. 



NVX produces this efficient amplifier with a footprint that almost fits within the margins of a sheet of binder paper. The built in circuitry protects the amp from overload or shorting and there are two 40A spade fuses located in one side of it.

Controls on the amp allow a subsonic filter to be tuned somewhere from 10 to 50 Hz to protect your speaker from potentially damaging low frequencies and a low-pass filter for 50-250 Hz to keep the the high notes out of the sub. There is also a bass boost dial capable of increasing output at 50 Hz by up to 18 dB, this boost frequency again is adjustable from 40-100 Hz. If you are planning on adding another powered device beyond this amp they added a set of RCA outputs that will pass the input source on to the next unit.

The amplifier fits deep in the the frunk of a non-AWD Model S and even deeper in the 2012 models. If one doesn’t want to locate the amp in the the frunk there is still a reserved space just beneath the sub-woofer enclosure that it fits nicely.

Wiring Kit


The XKIT42 wiring kit is out-of-this-worldly burly. 100% oxygen-free made of silver-tinned virgin copper, the power and ground wires are four gauge with seamless crimp ring terminals at one end of each and the power wire is partially sheathed in a protective mesh. These are supposedly larger overall than other brands and have 1862 strands of copper!

Final Impression

Sweet. It is so nice have a ‘real’ system now! I’m wondering if it would make sense to remove the factory 8″ sub from the other side of the trunk? The fit of everything in this kit is just perfect. I prefer the storage space under the enclosure compared to the space on top of the Tesla sub on the other side.

The sound output for the size of this kit is wonderful. If you want a really clean install and don’t want to spend a lot of time getting messy by laying your own fiber glass then really consider this kit. If you are looking for a moving violation or some show-car bass, maybe a 12″ or some top of the line 10″ speaker would be better. At $999.99, the NVX Tesla Model S Subwoofer System is probably hard to beat without compromising on form or sound quality. My speaker isn’t fully broken in yet and it seems to be hitting a little harder and louder as it gets used more. It sounds great and receives compliments from everyone who has heard it.
