Installing In-Wall Powered Subwoofer: Step3

Step 3

Insert wood mounting bracket through the hole, with the curved portion facing toward the center of the hole. The wood bracket should sit against the back side of the drywall and against the stud. Center the bracket up/down so it is centered vertically in the side of the hole. Screw the two pre-threaded screws into the stud. This will hold the bracket securely in place. (Repeat process for second bracket on opposite side of the hole.)
