5. Use a suitable cutting tool to remove the marked surface, and drill four holes for the
screws to pass through.
Installation Guide
(NOTE: Confirm you are happy with badge position relative to mounting holes)
6. Connect the wires before mounting the speaker. Be sure to observe the correct
polarity.
7. With the grille removed, mount the speaker using the four stainless steel screws, and
the stainless retainer clips supplied. DO NOT over tighten the screws, especially if the
mounting area is not flat.

Installation Tips
Any speaker will only perform to its best capabilities, when correctly placed in the
listening area. FUSION Engineers recognise that unlike a home or motor vehicle installation,
there are an extremely wide range of marine environments where speakers may be
placed. FUSION Full Range Marine Speakers are optimised to perform in the widest possible
range of mounting locations, but a little thought and care with placement will always be
rewarded with better sound.
Speaker
•
High frequencies are directional. Placing the speakers low down in the boat will lose
some of this information. (To improve dispersion of the high frequencies, the grille on
your FUSION Full Range Speaker has a uniquely designed “phase correction” feature in
the centre, for best performance with the grille on.)

able to hear both speakers in a stereo situation.
Bass is dependant on the area behind the speaker. Too small an area will restrict bass,
too large will compromise bass performance.
Placing a speaker such that it is very close to an open area (where sound from the
back of the loudspeaker has a very short path to compete with sound from the front
of the loudspeaker) produces the least bass.
•
If possible, try and make the area behind a speaker an enclosure.
Where the speaker is directly exposed to the outside environment, it is best if this is
a sealed enclosure. (Especially if the loudspeaker is exposed to “wash down”, as a vent
might allow water to collect in the enclosure.)
1. Check clearance around the mounting area before installation, ensuring the area is
free from obstruction, and there is adequate depth for the speaker.
2. Check that the area chosen for mounting the speaker is flat. If the area is curved, it
may not be possible to fit the speaker without “twisting” the frame.
Where the speaker is not so exposed (an inside cabin for instance), a better bass
performance can be had if the enclosure is a ported or vented type. To help you achieve
the best possible result see the optimum enclosure design recommendations. These are
by volume only, and for the ported option, an optimum vent size/length is given.
3. If the installation area is only slightly curved, use the extra thick closed cell foam
gasket provided.
4. Using the supplied mounting template, mark the correct diameter on the mounting
surface.

Speaker Grille Options
FUSION Marine Speakers (with the exception of MS-FR402) feature a variety of grille op-
tions, allowing you to customise your speakers to match or enhance the appearance of
your craft. Each pair of MS-FR602 and MS-FR702 speakers include a choice of three differ-
ent grilles and three different gel badges.

Standard Grilles
The standard grilles are factory-fitted to the speakers, and are
the most rugged and offer the highest level of protection. FUSION
recommends using the standard grilles in high traffic areas, or
where objects are liable to be moving around or knocking into the
speakers.
Trouble Shooting
Before you contact your FUSION dealer or service centre, FUSION requires that you do some
simple trouble shooting to help diagnose the problem.
If the FUSION speaker has been installed by a professional installation company, then we
recommend that you return to the company so the technician can assess the problem and
advise.
Cloth grilles
The cloth grilles are designed to enhance the internal cabin area.
The cloth insert is removable, via the screws on the inside of the
grille - allowing you to change the cloth to compliment the cabins
decor.
Problem
Solution
Check all connections from the source unit and
amplifier to the speaker terminals are correctly
connected
No sound
Sport grilles
The sport grilles provide a third grille alternative for your speakers.
Check the connections from the source unit/
amplifier to the speaker. Ensure the positive wire from the
source is connected to the positive of the speaker.
System lacks in bass
Ensure the speakers are mounted firmly to the mounting
surface
Check polarity
System lacks in high frequencies
Distorted sound
Check the bass / treble control settings on the source unit
Check all wiring
Check that it is not the surrounding panels of the craft rat-
tling. Check connections from the source to the speaker.
