Amazing

I admit that I was skeptical that new speakers could live up to the claims of increased volume and sound quality, but I was blown away. Prior to the complete Bavsound speaker changeout, my 2011 328i basic stereo could not fill the car with sound, even at full volume with the windows closed. Now the thing positively bumps, even with the windows open. I did the installation myself and ran into a self induced problem, but a quick call to Bavsound got me in touch with Jeremy who told me where to look for the trouble. Jeremy nailed it and my problem was no problem. I'm very pleased with the service, prompt delivery, packaging, and most of all the SOUND.

If I were any happier I'd be twin Bavsound subs.

For starters, as I am in sales, I have to commend Bavsound on their great marketing and promotional offers, finding their way to BMWCCA publications, Bimmerpost, etc. When I submitted my info to receive a promo offer for a free toolkit, the communications I received were really offering the value of the product. They clearly stated the advantages of their product. When the 0% financing option came along, I couldn't wait and decided to improve my bass. The install video was clear and even entertaining. The speakers were an obvious improvement over my h/k stock subs. Also, upon install and adjusting to the recommended EQ settings from Bavsound, I was enthralled to discover overall output, clarity and full spectrum response was improved. Being able to replace my subs without modifying my car and having the ability to swap back out before I sell or trade was well worth the few hundred bucks it cost. The only problem I had was a minor issue. I had wanted the free toolkit promo but it was somehow deleted from my order before checkout when I signed up for the 0% financing. I called customer service, almost three months later to express my frustration and admit that it was my fault that I didn't scrutinize the order before final submission. Without hesitation the gentleman I spoke with in customer service told me it would be no problem to ship me the toolkit. The customer service is as great as the speakers themselves. I would recommend Bavsound products to anyone that has a BMW and ears.

These work wonderfully

I think my speakers sound better than the HK system in my E90. The Ghost Underseat subwoofer is phenomenal. I love them!!

Extremely impressed

I've had the 8-ohm ghost subwoofers in my F30 335i for a little over a month now and I'm extremely impressed. I've got the HK system and while I was relatively happy with overall sound quality the low end was really lacking. Now that they've opened up they have really filled in the lower frequencies. I was considering adding a subwoofer in the trunk but I'm not convinced that it's needed anyone. I am very pleased with these the ghost subwoofers and high recommend them.

Frequently asked questions

Unfortunately, no.  Our Ghost Subwoofer Systems are designed to work together as a unit, with each component perfectly matched to the rest of the system and optimized for your exact BMW.  We also manufacture and warehouse the kits as complete units, so the individual components simply aren't available for sale outside of the entire kit.  
If you can put together IKEA furniture, you can install our Ghost Subwoofer System in your BMW. Here’s why it’s so easy to install: 

  • The Ghost Sub System is designed from the ground up to be easy to install. Installation doesn’t involve complex modifications to your BMW. Your new subwoofer enclosure will simply bolt right in.  Then, make a few wiring connections right in the trunk, and you're all set! (Some applications require slightly more work, but it’s always easy stuff!)


  • Every Ghost Sub System comes with extremely detailed installation instructions with photos, or a step-by-step video install guide, or both, so you’ll know exactly what to do.
Installation is so easy that we virtually never answer a phone call or email regarding the installation of a Ghost Sub System. To see how the Ghost installs in your BMW, click on the “Installation” tab and enter your vehicle information. You’ll be able to download installation instructions and view the video guides available for your BMW.
We have authorized Bavsound dealers all over the world. If there isn't a dealer near you, many of our customers use this list of local independent BMW mechanics throughout the U.S. and Canada and have reported great results.

If you can't find an installer that's convenient to you on that list, the great news is that because our products are incredibly easy to install, virtually any place that works on cars can perform the installation. You could take the car to your local mechanic, the BMW dealer, or even any well-regarded local car audio shop -- it’s your choice.

Our Ghost Underseat Subwoofers are the perfect upgrade to dramatically improve bass response in your BMW. Our subs pick up right where our midranges roll off, covering the full mid-bass to sub-bass spectrum. This gives your fuller, richer music, and eliminates any gap in your music between the midrange and sub-bass.

Our subs give you much tighter, louder, punchier bass, and drastically transform your music. They are engineered for efficiency, and maximize every watt of power generated by your amplifier to yield far more bass output than your factory subwoofers.


Regardless of impedance, all of our Ghost Subwoofer Upgrades are exactly the same in every way.  The only difference is just that -- the impedance.

Why do we have different impedance subwoofers?  Because our subwoofers are specifically impedance matched to your exact BMW’s audio system. We’ve done all the research and know what impedance your vehicle requires -- you simply need to buy, install, and enjoy!




Installation typically takes around 60 - 90 minutes.
We recommend to listen at medium - medium / high volumes for 10 hours to break in the rubber and adhesive in the subwoofers. You will notice a significant impact right when you install the subwoofers, but after the 10 hours of break in time, the subwoofers will reach their full potential.

Absolutely.  Our upgrades are all designed to sound phenomenal together, but are also engineered to sound incredible by themselves as well.

Each product compliments one another, with our Stage One speakers will bringing you incredible clarity, accuracy, and balanced sound quality, and our Bimmertech amplifier driving more power into your speakers and subwoofers to really take your system to the next level.


Because our subwoofers are completely plug and play, we are not able to add them to chassis that do not have factory underseat subwoofers. Our subwoofers plug directly into the factory wiring and use the factory enclosures.

That said, MANY customers don’t realize they actually already have factory underseat subwoofers.  So, even if you think you don’t, if our site says you do, you do (we promise, we’ve been doing this a LONG time!)


Place the details of your BMW into our vehicle configurator (year / model /  body style / audio system), and if it shows the subwoofers as available, then you ABSOLUTELY have the factory enclosures and wiring needed to add our subwoofer upgrades.

They’re easy to miss (and hard to hear), but we promise they’re there.  The subwoofer enclosures are dark, and the tops can only be seen when the seat is unbolted and pushed back. You will not be able to see the subwoofers by simply moving the seat back.
