Installing Your Speakers From The Rear Of The Bulkhead
A 9
A 10
Mark six screw holes. Use the smallest hole pattern that fits.
Remove the enclosure from behind the bulkhead.
CAUTION: Be sure the enclosure is not in place behind the bulkhead while drilling.
A 11
A 12
Drill the marked holes using a 1⁄8 inch
(.32 cm) bit. Use a center punch to make a slight indentation for your drill bit. This will keep the drill bit from “walking” away from the mark you have made.
You need to open one of the five marked drain holes because water can enter your 131TM marine speaker through the ports on the front of the enclosure.
Holding the enclosure in the mounting position you chose in Step 7, find the drain hole that will be at the lowest point when the speaker is mounted and break through the surface using a center punch, awl, or 1⁄8 inch (.32 cm) drill bit.
CAUTION: Acoustic performance is reduced if the hole is larger than 1⁄8 inch (.32 cm) in diameter.
