You can mount the speakers on the front/rear door of your car.

- A hole for mounting may already be cut out of the inner panel of the door(front or rear). If so, you need to modify the board only.
- Ensure that the speaker terminals, frame or magnet do not interfere with any inner parts,
- (such as the window), etc. Also ensure that the speaker grille does not touch any inner
- fittings, such as the window cranks, door handles, arm rests etc.
- Turn off the car ignition key.
- If the power is on, the click noise generated by the connection may damage the speakers.
- Cut out the mounting template from the packing box.
