WHAT IS THE GHOST SUBWOOFER SYSTEM?
EXCEPTIONAL BASS RESPONSE AND STEALTH, SPACE
SAVING DESIGN. RARELY SEEN, BUT ALWAYS FELT.
Simply add a Ghost Sub System to your BMW, and experience the real power and emotion of
your music.  Without giving up your trunk.
VEHICLE SPECIFIC DESIGN.
BECAUSE ONE SIZE DOESN'T FIT ALL.

Each Ghost Sub System is uniquely engineered and designed for your exact BMW. This
maximizes performance and trunk space.

ASTONISHING OUTPUT.
BASS THAT
IS NOT ONLY HEARD, BUT FELT.

By combining extremely efficient subwoofer design with stout amplification, and then
tailoring it to your exact BMW, every Ghost system delivers a deep, astounding bass
foundation that extends effortlessly to frequencies most subs never reach. So you can
feel your music, not just hear it.

UNPARALLELED PUNCH & ACCURACY.
POWERFUL SOUND IS NOTHING
WITHOUT CONTROL.

It’s easy to make a subwoofer system loud. It’s much harder to make one that combines
high output with incredible fidelity, capturing the movement of a bass pluck or the
"oomph" of a kick drum.

But we’ve done just that. How?

Our ultra-rigid aluminum cone subwoofer.

Because aluminum is so lightweight, we keep the extra mass for the amplifier to control or drive
to a minimum, yielding exceptional responsiveness and agility from the sub, meaning super-fast
transient response (more defined, detailed bass). And the incredible rigidity of the cone virtually
eliminates flex distortion, so what’s recorded is what’s played.

State-of-the-art amplification.

Every Ghost Subwoofer System includes our proprietary 250W Class G amplifier. With an incredibly low
THD of just 0.05%, a signal to noise ratio greater than 92dB, and a damping factor over 800, your
subwoofer receives an incredibly clean signal and the control it needs to produce tight, punchy bass.

HAVE YOUR CAKE.
AND YOUR TRUNK, TOO.

You use your trunk. And you need every bit of space you can get. That’s why the Ghost
Subwoofer System is designed to take advantage of unused space in your BMW, or in many
cases, the factory subwoofer location(s). So you get revolutionary performance -- and all the
space you need.

HIDDEN FROM VIEW.
BUT ALWAYS FELT.

Because of its space saving design and factory fit, the Ghost Subwoofer System is hidden
from view, keeping your BMW safe. There’s no evidence your audio system has been
upgraded -- until you turn it on.

EVERYTHING YOU NEED.
ANYONE CAN INSTALL IT.
EVEN YOU.

There are no additional parts to buy. Everything you need is in the box — subwoofer(s) +
enclosure (where applicable), wiring, and amp — plus step-by-step instructions with
photos and/or a video installation guide.

An afternoon with your BMW and basic tools is all you’ll need. But if you don’t want to
do it yourself, any car audio shop the world over can install the Ghost Subwoofer System.

See just how easy it is. Check out our installation guides & videos.

A FEATHERWEIGHT,
FIGHTING IN THE
HEAVYWEIGHT CLASS.

Despite its incredible output, every Ghost model adds just 19-38 pounds, depending on
your model. So you get heavyweight bass, but your BMW maintains featherweight handling.

RATTLE BONES.
NOT YOUR BMW.

Every Ghost Subwoofer System model utilizes a direct subwoofer-to-chassis mount,
drastically reducing the chance of rattles. So while no subwoofer system can guarantee
it’s rattle free, with the Ghost, chances are low.
