AM188201_02_V.pdf October 30, 2001 1 1 Snap the grille in place on the mounting flange. No hardware is needed to secure this part. You are now finished with the assembly. Enjoy your music system! Place the template over the area where the speaker is to be located. The round outer edge shows how much room to allow for the grille. The long end is used to judge the room needed behind the bulkhead. There are two perforated circles in the template. Snap out the larger one and mark the 7 1⁄8 inch (18 cm) hole with a metal scribing tool or pencil. Installing Your Speakers From The Front Of The Bulkhead If you cannot reach the mounting area from behind the bulkhead, you will have to mount the speaker enclosure by inserting it through the front. To do this you will need a 7 1⁄8 inch (18 cm) hole, the larger of the two perforated sections on your template. CAUTION: Determine whether any obstacles exist behind the mounting surface. To be certain, contact your boat manufacturer or dealer. Also, be certain that the enclosure will fit within the mounting area before drilling any holes. Remove the speaker cone shield from the enclosure.A 17 Installation from the front of the bulkhead A 18 B 1 B B
12 October 30, 2001 AM188201_02_V.pdf Use a half-round file or wood rasp to smooth out any roughness in the speaker hole you have cut. Using the sabre saw, cut the hole for the speaker, carefully staying just inside the line. Take your time; you want a smooth edged circular hole.B 4 Installing Your Speakers From The Front Of The Bulkhead Drill a starter hole that is large enough for your sabre saw blade. Be sure to drill inside and close to the line you have marked. Mark six screw holes from the largest hole pattern on the template, but do not drill yet. You may need to mark and drill a different set of holes along the same circle before finally attaching the flange. Note: These markings are important to help keep the saw blade inside the line you have just drawn. CAUTION: Be sure to stay inside the line you have marked, and in particular, be sure to stay well inside the hole pattern you have marked. The marked holes, or others along the same circle, will be used to secure the speaker and must not be too close to the speaker hole. It is also important to stay inside the line because any error you make could be visible after the speaker grille is installed. B 2 B 3 B 5
AM188201_02_V.pdf October 30, 2001 1 3 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. Installing Your Speakers From The Front Of The Bulkhead You will 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. Completing this task may require you to temporarily remove the flange from the enclo- sure. 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. B 8 B 9 Attach the mounting flange to the enclosure using six screws.B 6 B 7 Note: Twisting the ends of the wires together is not necessary. CAUTION: Acoustic performance is reduced if the hole is larger than 1⁄8 inch (.32 cm).
14 October 30, 2001 AM188201_02_V.pdf Remove the speaker enclosure. Tie a knot in each joined wire pair to protect the connection from being pulled apart. Installing Your Speakers From The Front Of The Bulkhead B 10 Reinsert the speaker enclosure. Note: For added protection against water enter- ing the bulkhead, you can apply a generic silicone sealant between the flange and the mounting surface. B 14 Drill six 1⁄8 inch (.32 cm) holes.B 13 B 12 Reinsert the enclosure into the wall in the position you determined in Step 7. If the outside circle of holes in the mounting flange line up with the ones you originally marked, remove the enclosure and drill at these marks. If they do not, make new markings that you can differentiate from your original set of markings.B 11 CAUTION: Do not drill while the speaker enclosure is in place.
AM188201_02_V.pdf October 30, 2001 1 5 Finally, snap on the grille to the mounting flange. No hardware is needed to secure this part. You are now finished with the assembly. Enjoy your music system! Install six screws, if possible. You need at least three screws installed and equally spaced. Remove the perforated speaker cone shields from the enclosure cartons. Insert the tabs of the shields into the speaker ports. This helps protect the speaker cone from potential damage during the installation process. Installing Your Speakers From The Front Of The Bulkhead B 15 B 16 B 18 Remove the speaker cone shield from the enclosure.B 17 Note: If you plan to use a screw gun to install the screws, you should first set the gun to its lowest torque setting (do not exceed 12 inch-pounds or 135.84 N-cm of torque). If the screw does not seat properly, finish installing the screw at the next highest torque setting, or by hand.
16 October 30, 2001 AM188201_02_V.pdf Problem What to do • Make sure the boat’s receiver is turned ON. • Make sure the power supply of the boat is connected and adequately charged. • Make sure the receiver is not set to MUTE. • Refer to the owner’s guide that came with your receiver. • Check connections to both the speakers and the receiver. Refer to “Test the speakers” on page 6. Correct any connection errors. • Disconnect the working speaker from the receiver. • Switch the cord of the “faulty” speaker from its original receiver connections to the other set of connections (the working speaker was originally attached to those connections). – If the speaker now works, the problem is in your receiver. – If the speaker does not work, continue below. • Remove the cord from the working speaker and connect it to the “faulty” speaker and either set of receiver connections. – If the speaker now works, the problem is in the original speaker cord. – If the speaker does not work, the problem is in the speaker. • Follow the same procedure for the problem of no sound from one speaker, as outlined above. • Adjust the bass and treble controls on the receiver. • Check the connections to make sure they are correctly in phase (+ to + and – to –). Refer to “Test the speakers” on page 6. Maintaining Your Speakers Cleaning the speakers Wipe the grilles using a soft cloth dampened with a mild detergent, such as dish soap. When cleaning near the speakers with a hose, be careful to avoid forcing water behind the grille, onto the driver, or into the acoustic ports. No other regular maintenance is required.
