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 nega-

tive). 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 131

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-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.
