12Install woofer wiring harness as shown. You can move the tower to the preferred listening position by shifting the unit from side to side and “walking” it.
13When you are confident the sub tower is correctly positioned, mark the floor with masking tape at each corner. Install the spikes by using a safe dolly to tip the sub tower back, remove the glides, and then screw the spikes into place. Make sure you thread the large black rubber washer onto the spike post before installing in the tower. Place the tower in a vertical position, and level front to back by tilting the tower back (at least 3 people are required) and adjusting the spikes.
