Love Of Sound
Exceptional Audio Fidelity
We took your factory speakers and re-engineered our upgrade for one thing: clarity. So you can simply swap your original speakers for ours without changing anything else in your audio system, and the result is smooth, natural, yet unbelievably detailed reproduction of your favorite music.

Easy OEM Swap
Same Dimensions, Higher Quality Throughout.
We engineer our speakers with the same unique size, shape, connectors, impedance, and efficiency as your factory speakers. That means installation is as simple as unbolting your factory speakers and bolting ours in, and it's totally reversible, too. No one will ever know you've upgraded your audio system except you. Unless, of course, they hear it.

2 Hour Install
No Expensive Install Process
Ever put together IKEA furniture? Then you can install the Stage One. Includes step-by-step instructions, and is designed to be easy enough that anyone can install it in just a few hours.

Music As Intended
Enjoy music as the artist intended.
We engineered speakers to produce higher quality sound: a wider range and more balanced reproduction of the bass and treble you are currently missing. That's because, unlike your car's factory speakers, we use proven audio technology: woven fiberglass cones, butyl rubber surrounds, and silk composite tweeters.

# How to Install Your Bavsound Ghost Underseat Subwoofers
Is Your Car Audio Upgrade Just a Placebo? Let's Find Out!
I remember the day I finally splurged on that premium amplifier I'd been eyeing for months. After hours of installation, sweating under my dashboard and pinching my fingers more times than I care to admit, the moment of truth arrived. I turned the key, cranked up my favorite track, and... wasn't immediately blown away.
"Did I just waste $600?" I wondered, panic setting in. But two weeks later, when my buddy Jake hopped in for a ride, he immediately noticed: "Whoa, when did your car start sounding like a concert hall?"
That's when it hit me – the improvements were real, but my ears needed time to recognize them.
The Strange World of Sound Perception
Most of us think we know what "better sound" means – it's louder, right? Not exactly. If you've recently upgraded your car's audio system or you're considering it, you might be surprised to learn that volume isn't the best indicator of quality.
During my decade working at custom car audio shops, I've seen countless confused faces when customers first hear their upgraded systems. "It doesn't sound much louder," they'd say, disappointment evident in their voices.
Here's the kicker – that's often a good sign!

Car already sounded good but gotta say happy about the improvement definitely considering doing the other upgrades for the rest of the speakers


Great Upgrade
I have a 2016 BMW 328i xdrive for a winter car and used to love it, however, I stopped driving much because I lost the joy of listening to music due to the stock speaker degradation over the past 4 years of ownership. The stock hi-fi speakers just had a nasty rasp in certain treble tones or vocals. I pulled the trigger and purchased the stage 1 kit. Worth every penny. Easy install and they are crisp and clear yet they have a distinct smooth bass. Very happy with them so far.

The bases sounds real good

The Ghost(s) in the Machine
The Ghosts in the Machine – Bringing My X3 to Life Upgrading my X3's sound system with Bavsound Ghost Subwoofers has been one of the best decisions I’ve made for my car. I listen mostly to jazz and classic rock, and the factory HiFi system just wasn’t cutting it. After adding the Ghost Subs along with the Bavsound speakers, the improvement has been incredible. The bass is deep and punchy without being overbearing. Jazz bass lines sound full and natural, and classic rock tracks have that powerful low-end kick they’ve always needed. The overall sound is richer, clearer, and much more dynamic. It feels like a proper sound system now, not just “good for a car.” Installation was fairly easy, though I did cheat a little and bought a pair of enclosures on ebay rather than taking mine apart with a hammer. Even so, everything fit perfectly, just like they promised. I’ve had no issues with distortion, even when turning up the volume for my favorite tracks. If you’re thinking about upgrading your BMW’s sound system, I highly recommend Bavsound Ghost Subwoofers. They’ve completely changed the way I experience music on the road, no extra amp required.

Huge improvement over the 20 year old speakers

Happy customer
I recently purchased the under the seat ghost subwoofers for my 2021 BMW 2 series and I have to say I was instantly highly impressed with the simplicity of the install and the upgraded sound quality. It is night and day difference and I am so happy with the outcome!! Next purchase will be the Stage One speaker upgrade. Great job!!

Sounds great

Great quality

Great quality

So so pleased!
Just ordered the stage one speak upgrade. The speakers came within days. The install was fairly simple. The video for the BMW X3 was easy to follow. The rear door install a little more tricky than the front. I wish the install video had showed the rear door, as I am person who appreciates a lot of detailed guidance. Either way, I figured it out. I noticed an immediate difference in the sound quality. The factory speakers were so disappointing and I actually found them annoying to listen to. The Bavsound speakers made an immediate, clear difference! I am back to enjoying music in my car. I had emailed back and forth during my initial order about getting the installation kit. The rep responded promptly and was so helpful. All items came at the same time, nicely packaged. The kit made the install a process one I was confident I could complete. Money well spent! I highly recommend the stage one upgrade. Has made me so, so pleased! Bavsound is the bomb! ☺️

A not so minor upgrade
This is by far the best investment I made! The sound quality is a definite difference even before the breakin period.
