Safety information

  • Secure enclosure and driver firmly in the boot. An unsecured enclosure becomes a projectile under full braking or in an accident.
  • Spare-wheel subwoofers: access to the spare wheel, tool kit, warning triangle and first-aid kit must be kept. Do not install if the boot has no emergency release.
  • Observe the vehicle's permissible gross weight and payload. Additional mass at the rear changes the handling.
  • Check the area behind the drilling point before drilling. Do not drill into load-bearing parts or tank, brake or cable areas.
  • Magnetic field: keep a distance from implanted medical devices such as pacemakers.
  • Installation by qualified persons only. Disconnect the battery as specified by the vehicle manufacturer before starting work.
  • Do not mount in airbag deployment zones, in the driver's field of view or above the footwell or pedals.
  • Do not work on high-voltage systems of hybrid and electric vehicles. Do not touch orange cables.
  • For dry interiors of road vehicles only. Not for marine, trailer, outdoor or wet-area use.
  • High volume can permanently damage your hearing and mask warning signals, sirens and announcements.
