VERTICAL ORIENTATION INSTALLATION STEPS:
(For horizontal orientation installation skip to next page)
1. Cut a hole in the drywall from existing stud to existing stud that is 46 inches
(117cm) high. This allows sufficient clearance to install 2x6s to the side studs
and install top and bottom 2x6 caps.
2. Use 2x6s to create a frame with 38.25" x 11.5" (971.6mm x 292.1mm) internal
dimensions (Figure 15). Secure to existing studs with nails or woodscrews.
3. Install new drywall up to the edge of the new 2x6 frame (post-drywall
installations only). Some spackle and tape work will be required.
4. Connect the signal wires to the terminals on top of the back box as described
on Page 6
5. Orient the back box so that the input terminals are closest to where you want
the horn to be located.
6. Lift the back box into the space defined by the frame.
DO NOT USE THE
MOUNTING BARS TO LIFT THE BACK BOX
; lift the back box by the
cabinet braces.
7. Allow the mounting bars to rest on the drywall to establish the proper back box
depth. In new construction installations, tack a piece of scrap drywall onto the
2x6 frame to establish box depth.
8. Use drywall or wood screws to secure the mounting bars to the frame or studs
under the drywall The mounting bars temporarily hold the back box in position.
9. Install rubber bushings into the top, bottom and middle mounting holes. Place
a metal washer onto each 5" deck screw and insert the screws through the
rubber bushings into the adjoining 2x6 frame. Tighten the screws enough to
expand the isolator mounts (bushings), but do not tighten beyond this point.
10. Make sure the back box is securely attached to the frame and then remove the
mounting bars completely. Discard.
11. Repeat step 8 with the remaining mounting holes
