Already busy building your own system or bringing an old one back to life?

Check out these tips first to make sure nothing stands in the way of enjoying your new speaker system:

  • Always check the whole system, such as cross-over components, of your old speakers. It is possible that a defect cross-over has caused the damage to your drivers, which you would like to prevent in the future.
  • Check out this table for BMW-models to find a match for your speaker model.
  • For stereo set-ups, always replace both drivers. This way, you ensure that they will not sound differently.
  • Check, check, double check your cables, components and other parts that could be lose and cause noise or even permanent damage!
