UNDERSEAT ACTIVE SLIM SUBWOOFER SL1779
Introduction
WARNING
WARNING
Please read this OWNER'S MANUAL thoroughly to familiarize yourself with each
control and function. We hope that your new underseat active subwoofer
SL1779 will give you many years of listening enjoyment. In case of problems
when installing your subwoofer, please contact [e-mail].
• DO NOT OPERATE ANY FUNCTION THAT TAKES YOUR ATTENTION AWAY FROM
SAFELY DRIVING YOUR VEHICLE. Any function that requires your prolonged
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.
• DO NOT BLOCK VENTS OR RADIATOR PANELS. Doing so may cause heat to
build up inside and may result in fire.
• MAKE THE CORRECT CONNECTIONS. Failure to make the proper connections
may result in fire or product damage.
• USE ONLY IN VEHICLES WITH A 12 VOLT NEGATIVE GROUND. Failure to do SO
may result in fire, etc.
This symbol means important instructions.
Failure to heed them can result in serious injury or death.

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.

INSTALLATION ( Fig.1) & ( Fig.2)
CAUTION
• Caution on connection terminals/parts
Keep electrically conductive objects away from the unit's terminals/parts
(power terminals, fuses, speaker input terminals, RCA connectors, etc.). Doing
so prevents a possible short circuit and damage to the unit.
MOUNTING
1. Attach the included mounting brackets to the SL1779 with the supplied
screws. (See to Fig. 1)
2. Once the brackets are mounted to the SL1779. Place the subwoofer in the
desired location within the vehicle. Before securing with screws, check to make
sure all screws can affix to a structurally solid surface while avoiding vehicle
wiring, components, etc. (See Fig. 2)
Note: For securing the mounting brackets to the vehicle, it may be necessary to
use longer screws (not included) to accommodate carpet thickness, etc.
NOTE:
To securely connect the ground lead, use an already installed screw on the
metal part of the vehicle (marked this is a good ground by checking continuity
to the battery (-) terminal. As much as possible connect all equipment same
ground point. These procedures will help eliminate noise.

CONNECTIONS (Fig.3)
Before making connections, be sure to turn the power off to all audio compo-
nents. Connect the red battery lead from the amp directly to the positive (+)
terminal of the vehicle's battery. Do not connect this lead to the fuse block.
To prevent external noise from entering the audio system.
• Locate the unit and route the leads at least 10 cm (3- 15/16") away from the
car harness.
• Keep the battery power leads as far away from other leads as possible.
• Connect the ground lead securely to a bare metal spot (remove any paint or
grease if necessary) of the car chassis.
• Your dealer knows best about noise prevention measures so consult your
dealer for further information.

5. Speaker Input Leads
These leads are input leads for use with head units not equipped with preamp
outputs. When not using the RCA Line Input connectors, you should connect
these wires to the speaker output leads of your head unit. The accepts input
from high power or standard power head units.
Note:
• Do not connect speaker leads together or to chassis ground.
• Use either RCA line level or speaker level inputs. Do not connect both at the
same time.
6. Battery Lead (Red)
Connect battery lead directly to BATT + Be sure to add a 30A fuse as close as
possible to the battery's (+) terminal.
7. Remote Turn-On Lead (Blue/White)
Connect this lead to the remote turn-on (positive trigger, (+) 12V only) lead of
your head unit.
Note:
If using speaker input level signal from the head unit, remote turn-on lead
connection is not necessary.
8. Ground Lead (Black)
Connect this lead securely to a clean, bare metal spot on the vehicle's chassis.
Verify this point to be a true ground by checking for continuity between that
point and the negative (-) terminal of the vehicle's battery. Ground all your
audio components to the same point on the chassis to prevent ground loops.

10. Crossover Frequency Adjustment Knob (LP FILTER)
Use this control to adjust the crossover frequency between 50 to 150Hz.
11. Input Gain Adjustment Control
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.
12. Power Indicator
13. Remote Adjustment Knob
Turning the remote bass level knob towards (+) increases the overall subwoofer
level, while turning the bass level knob towards (-) decreases the overall
subwoofer level.
(Note: can be used without connecting the remote bass level knob. However,
overall subwoofer level cannot be adjusted from the listening position.)
