Which BMW upgrade should I choose?

Start with your sound system: BMWs came with a standard system, a HiFi system (option 676) or Harman Kardon (option 688), and some kits only suit one of them. Front door speakers make the biggest first improvement, and replacing the underseat subs fills in the bass. For the full result, a plug and play DSP amplifier such as the Match UP 8BMW powers and tunes everything without cutting the factory wiring.

BMW Speaker Upgrades FAQs

Q: Will these speakers fit my BMW?

A: Most BMW 1, 2, 3, 4, 5 and X Series models use 4 inch door speakers and 8 inch underseat subwoofers, but fit depends on the model, year and sound system. Use the fit finders on this page or send us your registration and we will confirm.

Q: Do I need to cut any wiring?

A: No. These kits are plug and play: they use the factory mounting points and connectors, so the car can be returned to standard.

Q: Which BMW sound system do I have?

A: BMWs came with a standard system, HiFi (option 676) or Harman Kardon (option 688). Your option codes are on the vehicle order or can be checked from the VIN. Some kits suit only one system.

Q: Do I need an amplifier?

A: Speakers and subs alone are a clear improvement. Adding a plug and play DSP amplifier such as the Match UP 8BMW gives more power and lets the system be tuned to the car.

Q: Can CEN fit my BMW upgrade?

A: Yes. Our Beeston, Nottingham workshop fits BMW speaker, sub and DSP upgrades.
