Installing In-Wall Powered Subwoofer: Step5

Step 5

With the gold-plated spring-loaded speaker cable connectors positioned at the TOP of the subwoofer, insert the Subwoofer into the hole in the wall. Push the Subwoofer up against the drywall and hold it with your hand.
Insert your pencil or a long nail through each of the four holes in the front corners of the Subwoofer to mark each hole location on the wood bracket that is now directly behind each hole.
Remove subwoofer from the hole cut in the dry walland set it aside.
