UNDERSEAT ACTIVE SLIM SUBWOOFER SL1779

Introduction

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 support@recoilaudio.com.

• 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

This symbol means important instructions.

Failure to heed them can result in injury or property damages.

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.

Failure to do so may result in fire or electric shock.

4. Input/Power Wire Harness

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.

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.)
