Bose AM267565 manual Testing the space behind the hole

Steps to Installing

Testing the space behind the hole

You need a tape measure and a sturdy wire (such as a straightened coat hanger) 22 inches (55.9 cm) in length for this step.

1.Bend the wire as shown in Figure 17.

	(36.2 cm)

41/8 inches

(10.5 cm)

43/4 inches

(12 cm)

Tip: For greater accuracy, make the first bend a little long, measure again, and cut off the extra length at that end.

WARNING: If there is a possibility of electrical wiring in the space behind the wallboard, wrap the wire with electrical tape to prevent electric shock.

2.Make a mark 41/8 inches (10.5 cm) from the short end as an indicator of the proper front- to-back depth of the hole.

3.Use the bent wire to test for enough depth, front-to-back:

Insert the short end of the wire into the hole and straight back (Figure 18). Probe to make

sure nothing impedes inserting this end to a depth of 41/8 inches (10.5 cm). This indicates that the space behind the wallboard is deep enough for the front-to-back speaker dimension.

•If the wire goes in without a problem, proceed to step 4, below.

•If you cannot insert the wire to the 41/8-inch (10.5 cm) mark, you need to drill a new pilot hole elsewhere. Then repeat step 3.

4.Use the wire again to test the width, side-to-side:

With the short end still in the hole, reposition it (as shown in Figure 19) and rotate it 360˚ around the hole. This indicates if the wall space is wide enough on each side of the hole for the side-to-side dimension of the speaker.
