ZDSKB1 3-Way Speaker Kit for BMW
The ZDSKB1 is designed to drop directly into the same locations as the factory OEM speakers, with no modifications or complex wiring needed. Vehicle-specific connectors are included for a straightforward plug and play install.
The kit is compatible with BMW vehicles equipped with the HiFi Sound System (676) or Harman Kardon Sound System. It delivers a 3-way component setup — an 8″ (200mm) subwoofer, 4″ (100mm) midrange, and 1″ (25mm) silk tweeter — covering deep bass through to clear, detailed high frequencies.
The speakers fit the OEM locations precisely, ensuring a clean finish that integrates with the BMW interior without alteration. The vehicle-specific crossover operates at 12dB and connects via the supplied plug and play loom.
The 3-way configuration handles a wide dynamic range, with the subwoofer covering 37Hz – 3000Hz and the midrange/tweeter covering 100Hz – 20kHz. This allows the system to reproduce bass, midrange and treble with accuracy across a broad range of music genres.
The ZDSKB1 is built to maintain clarity at high volume levels. The 4 inch speakers are rated at 60W RMS / 120W max and the 8 inch subwoofer at 75W RMS / 150W max, so the system holds composure whether you are on the motorway or in slow traffic.
Installation is straightforward thanks to the plug and play design and vehicle-specific connectors, making it accessible even without extensive technical experience. The kit is engineered specifically for BMW audio system compatibility, removing the guesswork from fitment.
In summary, the ZDSKB1 is a direct-fit, 3-way speaker upgrade for BMW vehicles with the HiFi (676) or Harman Kardon sound system. It delivers improved bass, midrange and treble performance over the factory speakers with a simple, no-modification installation.

Who it suits
BMW owners who want a complete front upgrade, including the underseat bass, without cutting or rewiring. The speakers drop into the OEM locations. Check the vehicle application list, and see the ZDSKB1S if your car has a different factory system.
Our tech experts advise
BMW systems vary by model, year and audio option, so confirm the factory system before ordering. The kit runs from the factory amplifier, though an amplifier adds headroom. Installation is priced per vehicle, so get in touch with your make, model and year.

Frequently Asked Questions
Q: Will these speakers fit my car?
A: Most car speakers are standard sizes, but mounting depth and fitting rings vary by vehicle. Check the size in the Specification tab against your vehicle, or contact CEN with your registration and we will confirm fitment and any adapters or fitting kits you need.
Q: Do I need an amplifier to run these speakers?
A: Not always. Most speakers will run from a standard head unit, but a dedicated amplifier lets them perform at their best, particularly for component sets and higher power handling models. The RMS figure in the Specification tab is the guide to how much clean power they can use.
Q: What is the difference between coaxial and component speakers?
A: Coaxial speakers combine the tweeter and woofer in one unit for a simple like-for-like upgrade. Component sets separate the tweeter and woofer with a crossover for better imaging and detail, and suit installs where sound quality is the priority.
Q: Do these come as a pair?
A: Unless stated otherwise, car speakers are sold in pairs. Check the product title and What's Included tab, which lists exactly what is in the box.
Q: Can CEN fit these speakers for me?
A: Yes. CEN offers professional installation from our Nottingham premises. Contact us to book an installation slot or ask for a fitting quote.
Q: Which BMW sound systems is the ZDSKB1 for?
A: The ZDSKB1 is for BMW vehicles with the HiFi Sound System (676) or Harman Kardon Sound System. Check the Specification tab for the full vehicle application list, or contact CEN with your registration and we will confirm fitment.
Q: What speakers are in the ZDSKB1 kit?
A: It is a 3-way system combining an 8 inch (200mm) subwoofer, a 4 inch (100mm) midrange and a 1 inch (25mm) silk tweeter, with vehicle-specific crossovers.
Q: What is the difference between the ZDSKB1 and ZDSKB1S?
A: Both are 3-way BMW kits with the same driver line-up. The ZDSKB1 vehicle list covers HiFi (676) and Harman Kardon systems, while the ZDSKB1S list covers Basic, HiFi and Harman Kardon systems.
