Installing Your Speakers From The Front Of The Bulkhead

B 6

B 7

Attach the mounting flange to the enclosure using six screws.

Slide this assembly into the 71⁄8 inch (18 cm) hole and rotate the enclosure a full 360° to determine the best mounting position for the extended portion of the speaker enclosure.

When you have determined the best position, take a moment to make careful note of it. Then, remove the speaker enclosure.

You will need to open one of the five marked drain holes B 8 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. Completing this task may require you to temporarily remove the flange from the enclo- sure.

CAUTION: Acoustic performance is reduced if the hole is larger than 1⁄8 inch (.32 cm).

Connect the speakers. Be sure the receiver or amplifier is turned OFF. If possible, disconnect the power source.

Use the supplied silicone-filled wire nuts to secure the ends of each wire pair. Place the stripped end of the positive (+) right channel receiver wire together with the stripped end of the positive (+) right speaker wire. Place the wire nut over the ends of the wires and turn it in a clockwise direction. Turn it with firm pressure until it stops; there should be no uninsulated wire visible. Repeat this procedure for the remaining wire end.

Repeat the above procedure for the left speaker.

Check that all connections are made positive to positive (+ to +) and negative to negative (– to –). Tighten any loose connections before you plug in the receiver or amplifier and turn it on.

Note: Twisting the ends of the wires together is not necessary.
