CAUTION
Failure to heed them can result in serious injury or death.
DO NOT DISASSEMBLE OR ALTER. Doing so may result in an accident, fire or electric shock.
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 doctor
immediately.
USE THE CORRECT AMPERE RATING WHEN REPLACING FUSES. Failure to do to may result
in fire or electric shock.
USE ONLY IN CARS WITH A 12 VOLT NEGATIVE GROUND. (Check with your dealer if you are
not sure.) Failure to do so may result in fire, etc.
BEFORE WIRING, DISCONNECT THE CABLE FROM THE NEGATIVE BATTERY TERMINAL.
Failure to do so may result in electric shock or injury due to electrical shorts.
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 ALLOW CABLES TO BECOME ENTANGLED IN SURROUNDING OBJECTS. Arrange
the wiring and cables in compliance with the manual to prevent obstructions 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 DAMAGE PIPES 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 precautions may result in fire.

circumstances, please wait until the temperature drops
to a reasonable level before use.
This product is designed to shut down at high temperature to
prevent damage. If no sound is heard, please turn off the head unit
and then on again once the temperature inside the vehicle has

Only use the extension power cable included.
Also, please ensure to connect this directly to the +ve battery terminal. Should you feed off power from
the standard vehicle loom, the product may not function properly due to insufficient voltage.
The high current draw may also overheat the vehicle loom and create a fire hazard.
EN
It is vital to securely connect the earth lead to a metal part of the vehicle chassis.
Please ensure to connect the earth lead to a metal part of the vehicle chassis with a screw.
If the grounding of the earth lead is insufficient, the product may malfunction.
Any paint or coating on the earth point of the vehicle chassis should be removed with a file to enable a
good connection.
DO NOT EXCEED THE INPUT LEVEL SPECIFIED FOR THIS PRODUCT.
If there is distortion or a popping noise from the subwoofer, the input level is too high. Prolonged
use in this condition will result in the deterioration of performance and may lead to damage..
DAMGE CAUSED BY EXCESSIVE INPUT LEVEL WILL NOT BE COVERED BY WARRANTY.
If reducing the gain to prevent distortion leads to insufficient output, please install the
subwoofer closer to the listener. As a general rule, halving the distance will result in 4
times the volume.
DO NOT USE A MOBILE PHONE NEAR THIS PRODUCT.
Use of a mobile phone may cause interference and noise.

CAUTION - 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 wires insulation
from being cut by the metal edge of the hole.

By switching on the head unit, verify that the subwoofer is working.
Check that all electrical functions of the car are operational. (lights, indicators, horn etc.)
4. ADJUSTMENT
PHASE SELECTOR
LOW PASS FILTER ADJUSTMENT
GAIN ADJUSTMENT
DO NOT EXCEED THE INPUT LEVEL SPECIFIED FOR THIS PRODUCT.
CAUTION
If there is distortion or a popping noise from the subwoofer the input level is too high.
If the subwoofer has prolonged use in this condition, this may result in deterioration of
performance or may cause damage to the subwoofer.
4. ADJUSTMENT
1.
2.
Set the gain to MIN, Phase to NORM, LPF to CENTER before switching on the system.
Set the Bass/Treble adjustment to zero on the head unit. Set the volume to your average
listening level. It may help to use a music source that is familiar.
3.
Next, gradually increase the gain level. Increase the level to the point where the sound of
your system, as a whole, is balanced. If the gain level is set too high, the subwoofer may
begin to distort. Distortion may also occur if the volume is set too high on the head unit.
Check that the other speakers have not begun to distort, before proceeding with the
adjustment. If the entire speaker system in the car is distorting, reduce the volume of the
head unit.
EN
4.
5.
6.
Once the gain has been set, adjust the L.P.F (Low Pass Filter) at a frequency which
compliments your speaker system. (We recommend using CENTER as a starting point.)
Adjusting the L.P.F will change the output volume of the subwoofer. Repeat procedures 3
and 4 until the ideal setting is found.
The final adjustment is the PHASE of the subwoofer. While sitting in the driver’s seat and with
music playing, switch between NORM and REV. Select the setting which sounds better – The
ideal PHASE setting varies from car to car, depending on the location of the subwoofer and
the acoustic characteristics of the vehicle interior.
