DOUBLE THE BASS IN YOUR MINI, IN ABOUT AN HOUR.

SWAP YOUR FACTORY UNDERSEAT WOOFERS WITH OUR PLUG & PLAY UPGRADE KIT, AND GET INCREDIBLY POWERFUL, TIGHT BASS.

TIGHTER, PUNCHIER BASS

More bass without clarity is just noise. Our woofers are not only louder, they're cleaner and clearer.

INCLUDES EVERYTHING YOU NEED EXCEPT TOOLS

No expensive, complex additional amplifiers, wiring, hardware, or equipment required. Required tools sold separately.

DO-IT-YOURSELF, PLUG & PLAY, EASY INSTALL

Do-it-yourself installation in about an hour, even for a novice. You don't even have to remove your seats!

MORE SPACE = MORE FUN

Unlike other subwoofer solutions, upgrading your factory woofers takes up no extra space.

<p>DON'T JUST LISTEN TO YOUR MUSIC. <strong>FEEL IT.</strong></p>

DON'T JUST LISTEN TO YOUR MUSIC. FEEL IT.

This frequency response graph shows the significantly higher, more balanced output of our subs (yellow) vs. factory Harman Kardon subs (white).  Higher and "flatter" is better.  (NOTE: Your Mini shares the same woofers as BMWs, which is why you see them referenced in the graph)

2X THE BASS - Our woofers are 10 dB+ louder from 20Hz to 60Hz vs factory woofers, resulting in twice the loudness in this critical “sub-bass” range (and over 8x the sonic energy). You won’t just hear the bass; you’ll feel it.

NEARLY FLAT FREQUENCY RESPONSE FOR EXCEPTIONAL LINEARITY in the key sub / mid-bass frequency range from 40Hz to 200Hz (+ or - 3 dB). Which means "clean" and balanced bass.

100 DAY IN-CAR TRIAL, FREE RETURNS

Install, audition, and fully experience your new audio gear -- if you don't love it, we'll cover return shipping and give you a full refund (U.S. Customers only).

100% PLUG & PLAY

Install and fit just like your factory MINI woofers, right down to the bolts and factory style plug. 

SIMPLE, DO-IT-YOURSELF INSTALLATION

Can you put together IKEA furniture?  Then you can install these subs.

It takes less than 90 minutes and only our subwoofer installation tool kit, even for a total novice.

Simply unbolt your front seats, remove the woofer covers, unbolt your factory woofers, and install ours. That's it!

USE YOUR FACTORY AMPLIFIER AND GET EXCEPTIONAL BASS RESPONSE

We utilize your factory amplifier to generate amazing bass response in your MINI.

To do so, we've designed our woofers using technologies like oversized neodymium magnets and lightweight poly cone to maximize every watt of power they generate and translate that into raw output.

That means amazing bass response without having to replace your amplifier.

SUPER TIGHT, PUNCHY MIDBASS

Your factory underseat woofers aren't just subwoofers; they're midbass drivers. That means they play not just the lowest frequencies, but also "punchy" midbass frequencies like snare drums and high bass guitar notes.

Our woofers are designed to outperform the factory woofers for both subwoofer and midbass frequencies

But other underseat subwoofer upgrades on the market are only capable of playing sub frequencies, not midbass, so you miss a huge portion of the frequency range.

FACTORY MATCHED IMPEDANCE

Depending on your audio system, your factory MINI woofers come in 2, or 4 Ohm impedance.  Using the wrong impedance results in poor performance or risks damage to your amp.

Our woofers are matched to the impedance of your factory woofers (we have different versions for each) to maximize performance and ensure the longevity of your factory amplifier.

UPGRADEABLE DESIGN WITH 160W RMS / 320W PEAK POWER HANDLING PER WOOFER

Even though our woofers are designed to be extremely efficient to maximize the output of your factory amplifier, they're also built for upgradability.

You can power them with an aftermarket amplifier of your choice, up to 160W per channel.

Translation? If you'd like to melt your face off with absurd quantities of bass, you can -- just add an amp.

THE PERFECT MATCH TO OUR LEGENDARY SPEAKER AND AMPLIFIER UPGRADES

Amazing bass response can transform your listening experience, but if you want the absolute best, overall sound quality and clarity matters too.

That's why we engineered the Ghost Underseat Subwoofer Upgrade System to perfectly and seamless match our legendary Stage One Speaker Upgrade Kit.

4 YEAR WARRANTY. OUR PRODUCTS ARE BULLETPROOF. SO IS OUR WARRANTY.

Everything we sell has been engineered for durability and longevity, and we know what we sell will last. And last. And last.

That’s why our speaker upgrades and subwoofer systems are backed with our industry leading 4 year limited warranty.

So if something breaks, send it back. We’ll replace it at no charge, and cover shipping both ways.
