attention should only be performed after coming to a complete stop. Always
stop the vehicle in a safe location before performing these functions. Failure to
do so may result in an accident.
• KEEP THE VOLUME AT A LEVEL WHERE YOU CAN STILL HEAR OUTSIDE NOISES
WHILE DRIVING. Excessive volume levels that obscure sounds such as emergen-
cy vehicle sirens or road warning signals (train crossings, etc.) can be danger-
ous and may result in an accident. LISTENING AT LOUD VOLUME LEVELS IN A
CAR MAY ALSO CAUSE HEARING DAMAGE.
• DO NOT DISASSEMBLE. Doing so may result in an accident, fire or electric
shock.
• USE THIS PRODUCT FOR MOBILE 12V APPLICATIONS. Use for other than its
designed application may result in fire, electric shock or other injury.
• USE THE CORRECT AMPERE RATING WHEN REPLACING FUSES. Failure to do so
may result in fire or electric shock.

CAUTION
• HALT USE IMMEDIATELY IF A PROBLEM APPEARS. Failure to do so may cause
personal injury or damage to the product. Return it to our Service Center for
repairing.
• HAVE THE WIRING AND INSTALLATION DONE BY EXPERTS. The wiring and instal-
lation of this unit requires special technical skill and experience. To ensure
safety, always contact the dealer where you purchased this product to have
the work done.
• USE SPECIFIED ACCESSORY PARTS AND INSTALL THEM SECURELY. Be sure to use
only the specified accessory parts. Use of other than designated parts may
damage this unit internally or may not securely install the unit in place. This may
cause parts to become loose resulting in hazards or product failure.
• ARRANGE THE WIRING SO IT IS NOT CRIMPED OR PINCHED BY A SHARP METAL
EDGE. Route the cables and wiring away from moving parts (like the seat rails)
or sharp or pointed edges. This will prevent crimping and damage to the wiring.
If wiring passes through a hole in metal, use a rubber grommet to prevent
the wire's insulation from being cut by the metal edge of the hole.
• BEFORE WIRING, DISCONNECT THE CABLE FROM THE NEGATIVE BATTERY TERMI-
NAL. Failure to do so may result in electric shock or injury due to electrical
shorts.
• DO NOT ALLOW CABLES TO BECOME ENTANGLED IN SURROUNDING OBJECTS.
Arrange wiring and cables in compliance with the manual to prevent obstruc-
tions when driving. Cables or wiring that obstruct or hang up on places such as
the steering wheel, gear lever, brake pedals, etc. can be extremely hazardous.
• DO NOT SPLICE INTO ELECTRICAL CABLES. Never cut away cable insulation to
supply power to other equipment. Doing so will exceed the current carrying
capacity of the wire and result in fire or electric shock.
• DO NOT DAMAGE PIPE OR WIRING WHEN DRILLING HOLES. When drilling holes
in the chassis for installation, take precautions so as not to contact, damage or
obstruct pipes, fuel lines, tanks or electrical wiring. Failure to take such precau-
tions may result in fire.
•DO NOT USE BOLTS OR NUTS IN THE BRAKE OR STEERING SYSTEMS TO MAKE
GROUND CONNECTIONS. Bolts or nuts used for the brake or steering systems (or
any other safety-related system), or tanks should NEVER be used for installations
or ground connections. Using such parts could disable control of the vehicle
and cause fire etc.
• KEEP SMALL OBJECTS SUCH AS BOLTS OR SCREWS OUT OF THE REACH OF
CHILDREN. Swallowing them may result in serious injury. If swallowed, consult a
physician immediately.

Note: If the Remote Bass Level Knob will be connected in your system, make
sure to rotate the knob fully clockwise (set to +") before making the input gain
adjustment.
Set the SL1779 input gain to the minimum position. Using a dynamic CD as a
source, increase the head unit volume until the output distorts. Then, reduce
the volume 1 step (or until the output is no longer distorted). Now, increase the
amplifier gain until the sound from the speakers becomes distorted. Reduce the
gain slightly so the sound is no longer distorted to achieve the optimum gain
setting.

CONNECTION CHECKLIST (Fig. 5)
Please check your head unit for the conditions listed below: (Fig, 4)
a. The head unit does not have a remote turn-on or power antenna lead.
b. The head unit's power antenna lead is activated only when the radio is on
(turns off in the tape or CD Mode).
c. The head unit's power antenna lead is logic level output (+) 5V, negative
trigger (grounding type), or cannot sustain (+) 12V when connected to other
equipment in addition to the vehicle's power antenna. If any of the above
conditions exist, the remote turn-on lead of your must be connected to a
switched power source (ignition) in the vehicle. Be sure to use a 3A fuse as
close as possible to this ignition tap. Using this connection method, the Q9 will
turn on and stay on as long as the ignition switch is on.
If this is objectionable, a SPST (Single Pole, Single Throw) switch, in addition to
the 3A fuse mentioned above, may be installed in-line on the turn-on lead. This
switch will then be used to turn on (and off) the . Therefore, the switch should
be mounted so that is accessible by the driver.
Make sure the switch is turned off when the vehicle is not running, Otherwise,
the subwoofer will remain on and drain the battery.
