7. Be sure to run the speaker wire in

through the rear opening before 
reinstalling the baffle assembly.

8. Insert the mounting frame into the

cutout until the clamps snap into
place.

9. Insert the frame alignment tool 

horizontally into the center of the
frame. This tool functions as a
frame spreader, while the clamps
are being tightened, as shown in
Figure 15.

10. Starting from the lower right corner

and working in a diagonal torque
sequence, use a power screwdriver
to tighten each of the clamp screws
(only until almost snug). If needed,
adjust the mounting frame so it is
level and centered in the cutout.

11. Perform a final torque sequence.

Hand-tighten frame screws and
check each screw at least twice to
make sure they are fully tightened
to prevent rattles.

12. Remove the frame alignment tool.

13. Place the included fiberglass insula-

tion in the back of the mounting
frame, as shown in Figure 16. Cut an
“x” into the insulation and thread
the wire(s) through.

14. Make speaker wire connections.

Refer to the Making Connections
section on page 11 for instructions.

15. Slide the baffle into place in the

mounting frame.

NOTE: 

Be sure that the speaker wires

are clear of the woofer basket and not
too close to the woofer cone. Make
sure the wires are not pinched
between the baffle and the mounting
frame. Refer to Figure 16.

16. Use the spacer shim to center the

baffle inside of the frame while
securing with four 10-32 x 2-1/4-inch
screws. Loosely tighten the screws
while using the spacer on the bottom
side. Remove spacer and gauge the
other three sides before starting
final torque sequence. Proper cen-
tering of the baffle is critical to the
grille fitting properly.

17. Use the included 5/32-inch Allen key

to tighten until snug, as shown in
Figure 17.
