BMW M4 Bavsound Ghost Subwoofer Upgrade! GET DOUBLE THE BASS!!!
[dfads params='groups=239&limit=1&orderby=random']

GET DOUBLE THE BASS IN YOUR BMW OR MINI IN ABOUT AN HOUR.
Simply 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.

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.
HOW DO WE DELIVER BASS THAT'S LOUDER, CLEANER, AND TIGHTER WITHOUT CHANGING THE FACTORY AMP?
In a word, efficiency. Every watt of power generated by your amplifier yields about 2x the bass output with our woofers vs factory woofers.

If you're not familiar with the concept of "efficiency" in audio, just use this analogy: with your factory woofers, your amplifier is like a 200hp motor in a 4,000lb Camry.

With ours, it’s like the same 200hp motor in a 2,000lb Lotus Elise - twice the performance with the same power.

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
Installs and fits just like your factory BMW woofers, right down to the bolts and factory style plug. (NOTE: 2018+ X3 models and vehicles with “Base” audio systems require slight modification to factory enclosure and may necessitate additional tools)
