Here at John Kleis Audio we have considerable experience with BMWs and upgrading the inadequate audio systems in them. It’s such a popular manufacturer here for audio upgrades that we have obtained both a BMW 4 Series & a BMW 1 Series to showcase a few of the options we can offer people. You own a great car that deserves a great system to match it.

They are here almost every day the shop is open and is worth a listen to open your eyes (or ears!) to what can be achieved in these cars without actually seeing anything. Please call first to make sure the vehicle you want to listen to is at our premises.

Most BMWs, i.e. 1, 2, 3, 4, 5, 6, 7, X1, X3, X4, X5, X6, Z4, I3, I8 & Mini’s all share nearly identical set ups. This is a 4” speaker in the front (sometimes not even tweeters are installed), 6” mid-bass drivers under each front seat (so quiet we’ve given them the nickname, the ‘ghost woofer’) and a set of 4” speakers in the rear.

If you own any of the cars above get in touch and enquire about either of the set packages below or we can tailor something that is more specific to your requirements.

=============================================================================================================================

BMW Audio Upgrade Package 1

This consists of upgrading the front door speakers to the Bespoke BMW Audison Components & adding a powerful matching Audison 4 Channel Amplifier.

First, we soundproof as much as possible inside the door and also on the door card itself. This is using a mixture of Skinz Pro 2mm & 6mm Skinz Thermo acoustic liner to give the speaker an improved environment to work in and reduce resonance. This also helps with reducing road noise coming through the front doors. We then replace the basic 4” speakers with the Perfect Fit Audison Prima 2 Way Component System. This kit consists of 4” Speakers plus separate tweeters. We can either flush mount the tweeters in your factory mouldings or for the more original look (and an extra cost*) we can order in factory tweeter housings directly from BMW. All speakers plug directly into factory wiring so there’s no need to cut any cables. This keeps your manufacturer’s warranty completely intact.

The Audison amplifier gives the new front speakers more control and more power than the very limited BMW built in amplifier. In turn, meaning audio quality is improved even further at all volume levels and should you wish to, you will have a far more powerful & louder listening experience.
The Amplifier also powers the factory under seat woofers to make them more defined and controlled with more output meaning enhanced bass.
The Audison SR Amplifier we use redefines Class D amplification. With new hyper-efficient chassis design, the compact case size belies the brutish power available inside. Balanced high-level inputs ensure noise is kept to a minimum. This four-channel specimen can be run in four, three or two-channel mode and is 2 Ohm stable. Bypass, Hi pass and Lo Pass filters are all included.

The Audison SR4.500 runs the original under seat mid woofers in Stereo to reproduce the mid bass the way the Artist intended.
We also use an official Audison BMW harness that utilises the original plugs meaning no modification is carried out upon installation either. Great for keeping that vehicle as original as possible and not affecting any manufacturer warranty.
This package is £1599* supplied and fitted. As we are part of the Four Master Network you will have a 5 Year warranty on the system whilst the vehicle is in your possession.

BMW Audio Upgrade Package 2

As featured in our BMW M135i Demo Car this is our most popular package. This consists of fitting our package 1 above, plus replacing the factory 6” under seat speakers with the far superior Audison 8” Bespoke BMW woofers available in either 2ohm or 4ohm impedance for improved system composition versatility. We then power all these new upgraded speakers with the Audison SR4.500 Amplifier mentioned in Package 1. These Audison Under seat woofers are the best around and we have auditioned most, if not all of the options!

This Audison SR4.500 also runs the formidable Audison underseat 8” mid woofers in Stereo to reproduce the mid bass the way the Artist intended.

We also use an official Audison BMW harness that utilises the original plugs meaning no modification is carried out upon installation either. Great for keeping that vehicle as original as possible and not affecting any manufacturer warranty.

This system needs to be heard to be believed, which can be listened to via appointment in our own 2020 BMW M135i.
This package is £2200.00* supplied & fitted. As we are part of the Four Master Network you will have a 5 Year warranty on the system whilst the vehicle is in your possession.

BMW Audio Upgrade Package 3

For the audiophile listeners we offer the following.

High End Speakers, high end componentry, digital signal processing, custom EQ & tuning plus a top-notch installation all covered under a 5 year nationwide warranty.

 

The products we choose for this tried & tested package is the following…

 

Hertz Mille Legend Tweeters in front doors
Hertz Mille Legend Mid Range in front doors
Audison 8” Under Seat Drivers
Audison Prima Rear Coaxials
Audison AFM12.14 Amplifier with Built in DSP.

The front Hertz Legend speakers would be wired actively meaning each speaker has its own channel on the amplifier, in turn allowing us to create a more bespoke final tune & also to time correct the speakers individually instead of being restricted by an inline crossover.

We also use a bespoke BMW harness that utilises the original plugs meaning no modification is carried out upon installation either. Great for keeping your vehicle as original as possible and not affecting any manufacturer warranty.

This package comes to a total of £4,795.00

This is just the start of what we can offer for the audiophiles out there. We have a BMW 4 Series F32 Demo car that showcases the extremely high end Audison These Components plus Audison VOCE Amplification & lots more.

Feel free to book a demo of this vehicle to be blown away with what is possible!

All the above packages are not inclusive of the factory tweeter mounts if required. 

When installing the Bit DMI, depending on the specification of the car, it may require coding if a MOST amplifier is not factory provided with the car. If coding is not performed the DMI will not work. Contact us to find out more.

*”5 Years” means the period for which a vehicle is subject to retained ownership by the original customer.

 

All the above packages are what we recommend based on our extensive experience with BMW’s. They produce awesome results and will not disappoint. However, if you want something tailored for you please call us on 01189 866 224 or email us at info@johnkleis.com and we will talk you through options.
