1. Status Indicators

Green LED: the subwoofer is powered on and operational.

Red LED: the subwoofer is in protection mode and not operational. This problem is caused by input

overload, short circuit or extremely high temperature.

2. Input Gain Control

Adjust the input level of this subwoofer in order to match the output level from your source unit (head unit).

Important! Do not adjust the input level to maximum unless your input level requires it.

Follow the steps below to set your input level correctly.

a. On this subwoofer, turn the input gain control to minimum.

b. On your source unit, turn the volume to about 3/4 full level.

c. Slowly turn up the input gain control until you hear a small amount of distortion. Then turn down the gain

control until the distortion is completely gone. Leave the gain control at this setting.

3. Phase Control

Press to improve bass response (no or little bass sound) caused by time alignment problem in the audio

system. This problem usually results from having this subwoofer at a different distance from the listener

than the other speakers in the audio system.

4. Low Pass Filter (LPF)

Use this control to dene the frequency range you want the subwoofer to receive. The subwoofer will only

receive the frequencies below the one you set to reproduce sound.

Tip: If the other speakers of your audio systems are weak on the mid frequencies, set the LPF control

relatively high. If the midrange is well covered by the other speakers of your audio system, set the LPF

control relatively low to only receive lower frequency signal.

5. Bass Boost Control

Use this control to increase sound output level of the bass frequencies.

- 5 -

6. Low-Level Input (RCA Input)

Connect to the RCA outputs on your head unit. For best audio performance, low-level input is recommended

to input audio signal to this subwoofer if RCA outputs are present on your head unit or signal processor.

7. High-Level Input (Speaker Level Input)

Connect to the speaker wires on your head unit. If your head unit does not have RCA outputs, use the

speaker wires on the head unit for audio signal input from your head unit.

volume level of the subwoofer.

9. Power Terminals

: Connect to the closest point on the chassis of your vehicle.

REM: Connect to the remote output wire of your head unit for power on/off control on this subwoofer. No

need to make the remote connection if you use high-level input connection. High-level input connection auto

detects DC voltage to activate on/off control.

:Connect to the positive terminal of the 12V vehicle battery.

10. Fuse Holder

Insert a 15A blade type fuse (ATO) to provide protection of the circuitry. Do not use a fuse with a different

rating. Never replace the fuse with a wire or coin.

Subwoofer Setup Procedure

1. Secure this subwoofer in your vehicle. See the section “Placement” on page 6.

2. Disconnect the negative terminal of the vehicle battery to prevent a short circuit.

3. Establish audio signal input (low-level or high-level inputs). See the section “Low Level Input Wiring” or

“High Level Input Wiring” on page 7.

4. Make power connection on this subwoofer. See the section “ Power Connection” on page 8.

5. Recheck all connections to ensure correct and secure power/signal inputs.

6. Set the input gain control (INPUT LEVEL) to the minimum position.

7. Reconnect the negative battery terminal.

8. Turn on your source unit, then this subwoofer automatically turns on.

9. Set the source unit volume to about 3/4 full level, then adjust this subwoofer’s input gain control (INPUT

LEVEL) to just below the level of distortion.

10. Fine tune the various controls on this subwoofer to obtain best results.

Important notes on input level control

• The input gain control (INPUT LEVEL) is designed only to adjust the input level of the subwoofer in order to

match the output level of your source unit. It is not a volume control!

• Never adjust the input level to maximum unless your input level requires it.

• Failure to notice these instructions will result in an input overload to the subwoofer and excessive audio

distortion. It can also trigger protection mode, or may cause damage to the subwoofer or your speakers.

Protection Mode

When protection mode triggers, the red LED on the subwoofer turns on and the subwoofer shuts down.

One of the following reasons can trigger protection mode: input overload, short circuit and extremely high

temperature.

When the red LED turns on, take the following measures.

• Check the audio system carefully to determine what has caused the protection mode to trigger.

• Reset the subwoofer. Turn off the subwoofer (by turning off the head unit or other audio source which feeds

the subwoofer) and turn it on again.

• If the shutdown was due to either an input overload or a short circuit, correct the conditions which cause the

overload or short circuit then turn on the subwoofer again.

Placement

• Find a suitable location in the vehicle to place the subwoofer. A common location is in the trunk of a car or

behind the seat of a truck, as shown below.

• Make sure there is sufcient air circulation around the subwoofer.

• Place the subwoofer in the location away from moisture, and where connection cables are not pinched or

damaged by sharp objects.

Wiring

See the section “Installation Precautions” on page 3.

For safety, disconnect the negative terminal of the vehicle battery prior to wiring.

Use only high quality wires for reliable installation to minimize signal or power loss.

Make sure wires are not squeezed or damaged by sharp edges. Use rubber bushings for

penetrations.

Make sure all the cables are securely connected and bare wires are properly insulated.

Reconnect the negative terminal of the vehicle only when all wire connections are correctly and

securely made.

Low-Level Input Wiring

The subwoofer offers you two wiring alternatives for audio signal input from your source unit (head unit). Low-

level input wiring is preferred for waudio input. It provides an exceptional clean sound from the source unit.

Important! Do not connect both the high-level and low-level inputs from your source unit to the subwoofer at

the same time.

To the RCA audio outputs

of your head unit

• Using RCA cables (not included), connect two RCA jacks (LINE INPUT L/R) on the subwoofer to the RCA

audio outputs on your head unit. Make sure the left and right channels are correctly matched.

• To reduce the possibility of noise entering the signal chain, use high-quality, well insulated RCA cables. Run

the RCA cables away from large cable loops, electric fan and power cables.

High-Level Input Wiring

The subwoofer offers you two wiring alternatives for audio signal input from your source unit (head unit). Use

high-level input wiring for audio input from the source unit only when RCA audio outputs are not present on

the source unit.

Important! Do not connect both the high-level and low-level inputs from your source unit to the subwoofer at

the same time.

Battery

1. Using an 8 gauge (or heavier) wire, connect the terminal on the subwoofer to the metal frame of your

vehicle. Keep the ground wire less than 39” (100 cm) in length.

Scrape away any paint, rust or dirt from the ground point to provide a clean contact. Fasten the ground wire

on the ground point with a screw or bolt.

2. Using a 16 gauge (or heavier) wire, connect the REM terminal on the subwoofer to the remote output wire

of your head unit.

The REM terminal connection is used for power control. The subwoofer automatically turns on or off every

time the connected head unit is turned on or off.

If high-level input connection is made, you do not need to make the REM terminal connection. High-level

input connection auto detects DC voltage to activate on/off control.

If your head unit does not have the remote output wire, connect the REM terminal on the subwoofer to the

ignition switch wire of your vehicle for power on/off control. In this case, make sure your head unit is also

turned on or off with the operation of the ignition switch to avoid noise occurrence.

3. Using an 8 gauge (or heavier) wire, connect the terminal on the subwoofer to the positive terminal of the

12V vehicle battery through a correct fuse (not included). Keep the fuse within 18” (45 cm) of the vehicle

battery. It is important to connect the power supply through a fuse for protection of short circuits.
