Firstly, make sure that the speakers will fit in your chosen location. This may involve
the removal of the standard vehicle speakers. Please use the mounting depth and hole
cut dimensions as detailed in this manual for guidance.
• If necessary cut any material away to allow the speaker to sit correctly.
• Cut out the mounting hole and pre-drill any other fixing holes.
• If required, the protective grill can be removed from the gasket and omitted from the speaker
fitting.
• If the grill is to be fitted, screw through both gasket and speaker using the screw provided until
the speaker is securely fastened.
