1. First, drill a Φ330mm hole in the ceiling (consider the ceiling's load-bearing capacity; if reinforcement is needed, it is recommended to place a 20mm thick plywood above the ceiling. The plywood should be secured to the joist with explosion-proof bolts wrapped with钢丝绳, and the plywood should also have a Φ330mm hole for the speaker installation.)

2. Speaker input wiring: IN+ and IN-, and then connect the next speaker's wiring LOOP+ and LOOP-.

3. Install the product onto the ceiling by aligning with pre-drilled holes and tighten the screws.

4. After the product is securely fastened, insert the grill grommet into the slot and clip the grill in place.
