BEFORE YOU BEGIN INSTAL L ING
•Turn off the audio system. It isalso advisable
to disconnectyourbattery system whenever
performing installation work.
•Before cutting,drilling or inserting any screw,
check clearanceson both sidesofthe planned
mounting surface. Also check forany potential
obstacles,such aswiring harnesses,fuellines,
hydraulic lines,etc. Check both sides ofthe vessel
before cutting any holes.
•Wear protective eyewear at all timesand adust
mask and gloveswhen drilling orcutting.
Itisabsolutely vitalthatyourcomponent
system isconnected asshown in thismanual.
Failure to connectthe system asshown will
resultin damage to yourspeakerswhich is
NOT covered underwarranty.Do notsubstitute
differentcrossovernetworks!
TWEETER PROTECTION
The crossovernetworksare equipped with
an advanced electronic tweeterprotection
circuitdesigned to minimize the possibility
oftweeterfailure.Thiselectronic device
monitorscurrentgoing to the tweeterand
willdisconnectthe tweeterfrom the signal
when itsensesoverload.Should thisoccur
while listening to the audio system,simply
reduce the volume fora few secondsand the
protection circuitwillresetitselfautomatically.
SPEAKER PL ACEMENT CONSIDERATIONS
A componentsystem givesyou the ability to
place the wooferand tweeterseparately in your
vessel.Asa generalrule,the tweetersshould be
placed relatively close to the woofersforbesttonal
balance and mostcoherentimaging (the closer,the
better). Any separation greaterthan 8 inches(20
cm)islikely to resultin degraded sound quality.
Avoid placing tweeterswhere they willbe
blocked by objects(including seated occupants).
When selecting a mounting location,look atboth
sidesofthe vesselto make sure thatthislocation is
clearon both sides.

TWEETER INSTAL L ATION PROCEDURE
(SURFACE-MOUNT)
1)Choose a flatmounting surface.
2)Drilla 1/4-inch (6 mm)diameterhole atthe
centerofyourdesired mounting location (to
pass the tweeterwires).To preventcracking,
startwith a smallerdrillbitand gradually work
up the targetdiameter.
3)Place the surface mountcup atthe desired
location and orientation.Then mark the
three mounting screw locations with a sharp,
pointed tool.
4)Remove the mounting cup and drillthree
3/32-inch (2.38 mm)diameterpilotholesatthe
locations you justmarked.Itis also advisable
to use a hand-driven countersink toolon each
hole to furtherinhibitgel-coatcracking of
fiberglass panels.Depending on the thickness
ofthe mounting surface,itmay be necessary to
enlarge the screw holes slightly.
5)Place the mounting cup and align itoverthe holes
you justdrilled.Then insertthree ofthe supplied
#6 x3/4-inch philips-head mounting screwsand
tighten gradually with a hand screwdriveruntilthe
cup istightagainstthe surface.
6)Insertthe tweeterwires through the center
hole and then snap the tweeterinto place by
pushing in firmly.
7)Connectthe tweeterwires to the tweeter
outputterminals on the crossover.See Wiring
Diagram on page 4.
INSTAL L ING THE SPEAKERS
Once the mounting locationshave been
established,run speakercablesfrom the amplifier
outputsto the mounting locations.Ifyou are
running cablesthrough bulkheads,drillholesfor
the cable and use a urethane orplastic grommetto
protectthe wire from chafing in the hole.Make sure
thatthe cableswillclearany mechanicaldevices
in the boatand secure them with wire ties. Ifyou
are unsure aboutany partofthisprocess,please
contact your JL AUDIOdealer for installation help.
TWEETER INSTAL L ATION PROCEDURE
(FL USH-MOUNT)
1)Choose a flatmounting surface thathas
sufficientdepth to acceptthe mounting cup.
2)Cuta 1.875-inch (48 mm)diameterhole.
3)Preassemble the spring clip and mounting cup
as shown in Diagram A,using the supplied
machine screw
(Classic Grille Model shown.
Installation isthe same for Sport Grille
Models) .Do nottighten fully.
4)Insertthe cup into the mounting hole so that
the spring clip expands on the inside ofthe
mounting surface.
5)While holding the tweetercup in the desired
orientation,tighten the machine screw (with a
hand screwdriver)untilthe cup istightin the hole.
6)Insertthe tweeterwires through one ofthe
slots in the cup and then snap the tweeterinto
place by pushing in firmly.
7)Connectthe tweeterwires to the tweeter
outputterminals on the crossover.See Wiring
Diagram on page 5. Diagr am B

5)Remove the wooferand drilla pilothole (see
chartbelow)in each ofthe screw locations.Itis
also advisable to use a hand-driven countersink
toolon each hole to furtherinhibitgel-coat
cracking offiberglass panels.
6)Connectthe speakerwires from the amplifier,
the outputwiresto the tweeterand the jumper
wires to the wooferconnections.See Wiring
Diagram on page 5.
7)Place the woofer,with itsgrille,into
the opening.
8)While holding the speakerfirmly in its
mounting location,place the #8 x 1 3/8-inch
pan-head mounting screws (with washers)and
snug in a criss-cross pattern,then tighten with a
hand screwdriverin a criss-cross pattern.
WOOFER INSTAL L ATION PROCEDURE
Diagram C shows the typicalinstallation
procedure into a fiberglass panel,using the
supplied hardware (Classic Grille Model shown.
Installation isthe same for Sport Grille Models).
Always follow propersafety procedures Use eye-
protection atalltimes and a dustmask and gloves
when cutting.
1)Choose a flatmounting surface thathassufficient
depth and airspace behind itto acceptthe
componentwoofer.
2)Cuta 6.25-inch (159 mm)diameterhole.
3)Run the speakercable from the amplifier
outputto the mounting location.
4)Place the wooferin the hole and mark the screw
hole locationsusing a sharp,pointed tool.
