• 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 emergency vehicle sirens or road warning
signals (train crossings, etc.) can be dangerous and may result in an accident. Listening at loud
volume levels in a car may also cause hearing damage.
• Do not disassemble or alter.
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. (Check with your seller if you are not sure.)
• 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 allow cables to become entangled in surrounding objects.
Arrange 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 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 precautions 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 bolls or screws out of the reach of children.
Swallowing them may result in serious injury. If swallowed, consult a physician immediately,

• Stop using immediately if a problem occurs.
Failure to do so may result in personal injury or product damage. Return it to the dealer or the nearest
service center for repair.
• It is recommended that you seek assistance in installing and connecting the product to qualified
car audio professionals. The wiring and installation of this device requires special technical skills and
experience. To ensure safety, it is recommended to contact professional car audio experts for
installation and electrical work.
• When wiring, do not allow it to be pinched or crushed by sharp metal edges. Route cables and
wiring away from moving parts (such as seat rails), sharp or pointed edges. This will prevent crimping
and damage to the wiring. If the wire passes through a metal hole, use a rubber grommet to prevent
the metal edge of the hole from damaging the wire insulation.
• Do not install in places with high humidity or dust.
Avoid installing the device in places with high humidity or dust. If moisture or dust gets inside the
device, it may break.
• Do not expose the subwoofer to direct moisture, as this may cause a short circuit or fire.
• When mounting the subwoofer, leave a small amount of free space on all sides.

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.
To prevent external noise from entering the audio system:
Route the wires from the device at least 10 cm (3-15 / 16 inches) away from the vehicle seat belt. Route
power wires as far away from other wires as possible. Connect the ground wire securely to the metal
hole (remove paint or grease if necessary) on the vehicle body.
Qualified car audio professionals know best about interference prevention measures, so please
contact the experts for more information.
Fuse: When replacing a fuse, use only the fuse rating recommended by the manufacturer. Using a
fuse with a higher or lower rating may result in damage to the device, fire, or electric shock.

Be sure to turn off the power of all audio components before connecting. Connect the red wire from
the amplifier directly to the positive (+) post on the vehicle's battery. Do not connect this wire to the
fuse box.

1. Connecting power wires
Correctly select the gauge of the power wires (not included). Recommended power wire gauge are 8
AWG as this will affect the correct operation of the device. Connect positive wire to positive battery
terminal. Connect the battery Fuse Holder 30A fuse closer to the battery (sold separately). Connect
the negative cable to any part of the car chassis and secure with a screw. At the same time, check
that your actions do not violate vehicle construction and components.
2. Connecting the control wire to turn on the amplifier
Control wire (not included) for turning on the subwoofer amplifier. Connect this terminal to the
corresponding wire on the head unit. Another method is to connect the REMOTE wire to the car's
ignition.
3. Interconnect cable connection (RCA, low level input)
Connect an RCA cable (not included) in the following sequence: WHITE - connect to the left channel,
RED - connect to the right.
4. GAIN adjustment (LEVEL)
The GAIN (LEVEL) knob is used to control the sensitivity of the subwoofer amplifier according to the
source (car head unit) output voltage. The sensitivity knob is related to volume control. Play audio
content in CD quality on your car head unit and increase the volume up to 75% of the maximum
possible. Set the GAIN control to minimum and slowly turn the GAIN knob clockwise until the first
sound distortions appear. Then reduce the gain slightly by decreasing GAIN knob counterclockwise
to get the most undistorted sound possible.
5. FREQ adjustment (LPF)
FREQ know is used to cut high frequencies that the subwoofer cannot reproduce. Adjust the filter
according to the frequency range of the subwoofer.
6. Phase switch 0° to 180°
The subwoofer output phase can be set to the standard subwoofer mode - phase 0° (button - Off) or
the subwoofer out-of-phase mode -180° (button - On).
7. Remote Gain Adjustment
Remote Gain Adjustment Knob allows the user to adjust the overall bass level of the subwoofer.
Turning the remote bass level knob towards {+) increases the overall subwoofer r level, while turning
the bass level knob towards {-) decreases the overall subwoofer level.
Note: BA8 can be used without connecting the remote bass level knob. However, overall subwoofer
level cannot be adjusted from the listening position.
