Setting Up

Unpack the carton

Carefully unpack your speakers and save all packing materials for possible future use. Do not attempt to use your speaker system if any part of it appears damaged. Notify Bose® Corporation or your authorized Bose dealer immediately. Check that your system contains the parts identified in Figure 1. For shipping, the mounting flange is packed inside its speaker grille. Separate these components before installation.

Notes: Please remove the perforated drilling and cutting template from the inner carton containing the grille and mounting flange. Also remove the perforated speaker cone shields from the inner cartons containing the enclosures. You will need the template and shields during installation.

Now is a good time to record each speaker serial number on page 2 of this guide and on your warranty card.

CAUTION: The 131TM marine speakers are not intended to be installed in automobiles.

Setting Up

Select the locations for your speakers

In selecting locations for your speakers, understand that there are two possible mounting options. It is easiest to mount the speakers from behind the mounting surface. However, if you cannot reach behind the mounting surface, you may cut a larger hole that allows you to insert the speaker enclosure from the front of the mounting surface. See Figure 2. With this in mind, find a location that:

Allows sufficient room to snap on the grille. Use the template to be sure there is enough area around the holes you will cut in the bulkhead.

Allows sufficient room for the speaker enclosure behind the bulkhead. During installation, the enclosure requires 412 inches (11 cm) of mounting depth. However, once installed the enclosure requires only 312 inches (9 cm) of mounting depth and 12 inches (31 cm) of extension. The enclosure may be rotated in a complete circle, but attaches to the mounting flange in only one position.

Accommodates the speaker wire provided. Lay out lengths of wire that comfortably reach from the receiver to each speaker. Be sure the wires are secure and protected from being pinched, pulled, or damaged in any way.

Is not close enough to adversely affect any compass.

Note: The magnets in the speakers will affect a boat compass. Avoid mounting the speakers closer than three feet from the compass. If necessary, a marine installer can help correct any deviation.

Installing Your Speakers

Test the speakers

It is a good idea to test your system before installation. With the power turned off, connect the receiver to the speakers.

The provided speaker cord consists of two insulated wires; one is marked or ribbed, and is always positive (+). The plain wire is always negative (–).The wires correspond to the red (+) and black(–)terminals on the back of the speaker, receiver, or amplifier. Place the stripped end of the positive (+) right channel receiver wire together with the stripped end of the positive (+) right speaker wire. Then place the stripped end of the negative right channel receiver wire together with the stripped end of the negative right speaker wire. Repeat this procedure for the left speaker.

Be sure to connect each wire to the proper terminal (positive to positive, negative to negative). For this test, just twist the wire ends together. You will use the supplied wire nuts for the permanent connections.

When you are satisfied that everything works, disconnect the speakers and continue with the installation.

Mounting the speakers

CAUTION: Be sure to mount your 131TM marine speakers on a bulkhead only. Do not cut holes in the hull. We recommend you consult a marine installer before drilling or cutting any holes. Choose a safe spot for drilling. Do not mount the speakers on surfaces with concealed hazards, such as electrical conduits or plumbing.

The cutting and drilling template

Locate the cutting and drilling template. It is perforated into the inner carton that contained your grilles and mounting flanges. The template has four functions.

1.It helps you position the speaker enclosure by showing how much room to provide for the extension of the enclosure behind the bulkhead.

2.It shows you how much room to allow for the snap on grille.

3.It assists you in cutting the appropriate hole size in the bulkhead wall.

4.It helps you drill the mounting screw holes in the bulkhead.

The template has two punch-outhole diameters. Use the smaller size for installation from behind the bulkhead. Use the larger for installation from the front. See Figures 2 & 3.

Installing Your Speakers From The Rear Of The Bulkhead

A Installation from the rear of the bulkhead

Choose the 538 inch (13.6 cm) diameter hole size if you can comfortably hold the speaker enclosure from behind the wall while installing screws from the front. This is the preferred mounting method. If the hole you cut is not perfect, any slight overcut will be hidden by the grille.

A 1 Determine that there is enough room by reaching into the mounting area and

sweeping with your hand. Determine where you will drill the hole for the

speaker. You should also experiment by placing the speaker enclosure behind

the bulkhead before making your final selection. Any orientation of the speaker enclosure is acceptable.

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.

A 2 The round outer edge of the template shows how much room to allow for the grille. The long end is used to plan for room for the enclosure behind the bulkhead. There are two perforated circles in the template. Snap out the smaller one.

A 3

A 4

Place the template over the area where the speaker is to be located and mark the 538 inch (13.6 cm) hole with a metal scribing tool or pencil.

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.

Using the sabre saw, cut the hole for the speaker, carefully following the line. Take your time; you want a smooth-edgedcircular hole.

Use a half-roundfile or wood rasp to smooth out any roughness in the hole you have cut.

Hold the speaker enclosure up to the hole from behind the bulkhead and find the best position for the extended portion of the enclosure. Be sure the enclosure is hidden behind the bulkhead. If the enclosure does not fit, use the file or rasp to enlarge the hole.

Place the mounting flange so that it interlocks with the enclosure and is flush with the mounting surface.

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 18 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, or18 inch (.32 cm) drill bit.

CAUTION: Acoustic performance is reduced if the hole is larger than18 inch (.32 cm) in diameter.

Installing Your Speakers From The Rear Of The Bulkhead

A 13 Connect the speakers. Be sure the receiver or amplifier is turned OFF. If possible, disconnect the power source. Use the suppliedsilicone-filledwire 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.

A 14

A 15

Tie a knot in each joined wire pair to protect the connection from being pulled apart.

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.

Note: For added protection against water entering the bulkhead, you can apply a generic silicone sealant between the flange and the mounting surface.

A 16 Replace the enclosure behind the bulk head and place the mounting flange so that it interlocks with the enclosure and lines up with the drilled holes. Attach the flange to the mounting surface using six screws.

Next, install six screws through the flange into the matching holes in the enclosure.

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 inchpounds or 135.84N-cmof torque). If the screw does not seat properly, finish installing the screw at the next highest torque setting, or by hand.
