To ensure a secure and vibration-free installation, follow these steps:

1. Choose the desired location for the speaker, ensuring that there is enough space in the ceiling to accommodate the speaker's dimensions (13 x 11 x 9.8 inches).
2. Use the provided mounting template to mark the cutout area on the ceiling.
3. Carefully cut out the marked area using a drywall saw or other appropriate tool.
4. Run the speaker wire from your amplifier or receiver to the speaker location, leaving enough slack for connection to the speaker terminals.
5. Strip the ends of the speaker wire and connect them to the gold-plated terminals on the speaker, ensuring that the positive (+) and negative (-) terminals on the speaker match the corresponding terminals on the amplifier or receiver.
6. Insert the speaker into the cutout, aligning the mounting tabs with the edge of the hole.
7. Tighten the mounting tabs using a screwdriver, which will secure the speaker to the ceiling. The patented rotating cam system will ensure a snug fit.
