Installation in Greenhouses

The speakers are installed in the greenhouse behind the sticker that is attached on the roof. The speakers are secured by the wire ropes. The wire ropes are supposed to be attached to the speakers. If not, loop the wire rope through the hole in the corner of the speaker. Put the wire rope between the glass and the metal structure at the tip of the greenhouse and secure it at the outside of the house (hole where the lock goes).
Secure the wire rope with wirestop sleeves.
