HOW TO DETERMINE WHICH AUDIO SYSTEM YOUR VEHICLE IS EQUIPPED WITH
BASE STEREO SOUND SYSTEM
The base level stereo sound is standard on pretty much all Australian delivered models. Specifics vary by vehicle, but this audio system is generally characterized by a lack of an external amplifier, and usually just 6 total speakers (often without tweeters), and generally very poor overall performance. There is no option code for the base stereo system.
HI-FI SOUND SYSTEM - S676A
Hi-Fi Speaker System comes as standard on only a few Australian delivered models. Although exact specifics vary from vehicle to vehicle, this audio system is generally characterized by 10 total speakers and an external amplifier, no user adjustable "DSP" processing or equalizer settings, and "average" overall performance. The option code for this system in a VIN search is S676A.
HARMAN KARDON SOUND SYSTEM - S674A/S688A
If you have "HK" or Harman Kardon labels in your interior, you have this audio system. If you do not have those labels, then you do not have this audio system. The option code for this system in a VIN search is S688A. On some models such as the 1 and 2 Series, option code S674A 'Hi-Fi System Harman Kardon' may be installed. This system is very simlair to the normal Hi-Fi sytem but comes with more speakers and is not as powerful as the premium Harman Kardon system.
TOP HI-FI / LOGIC7 / PROFESSIONAL DSP - S677A
This is BMW's "premium" audio system referred to internally by BMW as "Top Hi-Fi" or "Hi-Fi System Professional DSP." There are a number of different names under which this system may be marketed depending on the year and model of your BMW including Logic7, Premium "DSP" and Professional DSP. If your vehicle is equipped with one of these audio system types listed above or referred to by your dealer or invoice as having option code S677A. If you have an "M" vehicle (M3, M5, etc.) you may have DIRAC or Enhanced Premium Sound (EPS). Please view the descriptions of those audio systems to determine whether you have DIRAC or EPS, or check with your dealer.
DIRAC SOUND SYSTEM - S752A*
Available only on "M" model BMWs such as the M3, M5, M6, and so on, this was BMW's "ultimate" audio system, positioned above the Premium audio system offerings. This offering was later replaced by BMW's "Enhanced Premium Sound" system. Changes from the Top Hi-Fi Premium (S677A) system are different speakers, a more powerful amplifier, additional DSP processing, and better hardware crossovers. DIRAC can be identified by silver trim rings on interior door speaker covers and a silvery metallic speaker cone visible through the front speaker covers.
ENHANCED PREMIUM SOUND - S752A*
Available only on "M" model BMWs such as the M3, M5, M6, and so on, this is BMW's "ultimate" audio system, positioned above the Premium audio system offerings. This offering replaced the earlier "DIRAC" system. If you do not have an "M" car, you do not have this audio system. Changes from the "normal" Premium (e.g. Logic7, Harman Kardon, etc.) system are different speakers, a more powerful amplifier, additional DSP processing, and better hardware crossovers. Enhanced Premium Sound is difficult to identify physically as it has the same number of speakers and locations as the "normal" Premium audio systems.

TELL ME MORE
After years of requests, Bavsound have finally brought these drivers to the E38 space. They're the world's only direct-fit, plug and play E38 specific woofers, (you'll have to add new spade terminals which are included) and take around 20 minutes to replace your old, blown woofers.
These drivers are optimized to perform on the OE DSP amplifier. They are functioning as woofers (not dedicated subwoofers), and due to the size of the drivers you can expect brilliant performance across the spectrum from 50Hz-300Hz.
The UV Treated cones and dust caps protect the speakers from sun exposure and deterioration over time. With Bavsound's industry-leading 4 year warranty, you can expect a lifetime of flawless performance.
To note: These are not your traditional subwoofers; they will not shake the car, and they will not rattle the rearview mirror. These are designed as a direct-fit, impedance and efficiency-optimized improvement of the factory BMW woofers.
Set of 4 subwoofers. Gaskets included separately and to be applied directly to underside of woofer basket before attaching to factory enclosure.

Wiring connections inside of factory enclosure
We tend to see solid green (negative -) and green w/black stripe (positive +) in the majority of the factory enclosures. If you see any variation, refer to your factory speakers for the correct polarity. The larger terminal is positive and the smaller terminal is negative.
New Bavsound Woofers
Crimp new spade terminals to your factory wiring using a pair of wire crimpers. Negative is the smaller terminal on your new speaker. Positive is the larger terminal on your new speaker.
The technical jargon for you audio geeks...
- Black glass fibre reinforced cones offer improved strength over conventional polypropylene or paper cones. This design reduces cone breakup at high volumes and heavy listening demand periods. It also reduces cone resonation and allows for smoother and more dyanmic transitions across complex musical passages.
- The Bifilar wound voice coil designs allow you to put more copper in the gap in a smaller package. The benefit of the smaller footprint allows a more precise overall motor design and improved accuracy in alignment of the moving coil to the speaker motor. Perodical staging of the voice coil with a variety of heating and cooling stages helps the speaker with offgassing typically found in conventional coils, thus preventing instances where thermal conditions of heavy use can lead to premature failure.
- Complete Nomex fibre reinforced spiders give the drivers a broader level of linearity and control across the entire operating sound spectrum. Nomex is extremely stable and offers a broader level of linearity at an extremely wide range of listening levels without the loss of control at the extreme end limits of the speaker's design without a compromise in performance.
- In addition, complete Nomex glass fiber reinforced spiders offer significantly improved longetivity and relibility in a much broader range of environmental conditions.
- Dampened steel baskets use variations in geometric shapes within the basket design to improve the overall strengh and optimize design resonant frequencies outside of the speaker's optimal operating frequencies. As such, dampened designs eliminate the possibilities of material resonance in the operating range which can created unwanted and undesired sounds while listening to music.

Fantastic customer service from the team at Southern BM. Expertly repaired my 2011 323i and did so without the attitude and excessive cost of a dealer. Thank you and I will be back for all future servicing.

My first dealing with Southern BM was a pleasant one. I had some springs and shocks installed and Sean was a delight to deal with. Knowledgeable, helpful and offered solutions when not everything went to plan. I would happily recommend them.

First time at Southern BM today and it won't be my last. Efficient and quality service as I'd expected at a much more reasonable price than a BMW Dealer. The only downside, you'll drop your car off and will end up drooling over the m3s and m4s out front!
