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 131M marine speakers are not intended to be installed in automobiles.
You will need the following tools to complete this installation:
•Phillips-head screwdriver.
•An appropriate cutting tool for the surface to be cut. For installation in fiberglass or wood,
we recommend a sabre saw. Use a short blade, and have some extra blades available. A
hole saw may also be used. Large diameter hole saws are available and they allow you to
make circular cuts on a flat surface.
•Drill with the following bits:
- For drilling the screw holes a 3⁄

- For drilling the starter hole, use a 5⁄16 inch (.8 cm) bit.
•Center punch or awl.
•Half-round file or rasp.
•Eye and ear protection; dust mask.
CAUTION:
Failure to follow these instructions voids all warranties on your speakers. If you

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 4
enclosure requires only 31⁄2 inches (9 cm) of mounting depth and 12 inches (31 cm) of
extension. The enclosure may be rotated in a complete cir cle, 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 Y our Speakers
T est 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 corr espond 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:
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.
Be sure to mount your 131TM marine speakers on a bulkhead only. Do not cut

The template
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-out hole diameters. Use the smaller size for installation from
behind the bulkhead. Use the larger for installation from the front. See Figures 2 & 3.
