Features

1. Fuse: Do not use a fuse with a different value than the one provided.
2. +12V, Remote, and Ground terminals.
3. Low-Level RCA Inputs: Low-level inputs are the recommended way to introduce an audio signal to the subwoofer if RCA outputs are present on your head unit or another signal source (such as a sound processor).
4. Auto Power-on: The auto power-on function is for high level (speaker level) connections (see no. 6). When the switch is in the “ON” position, the subwoofer will turn on when there is a signal input. If there is no signal input, the subwoofer will automatically turn off. If you prefer to use the remote turn-on function, leave the switch in the “OFF” position.
5. Phase Shift: Use this button to help compensate for time alignment problems. Such problems usually result from having the subwoofer positioned at a different distance from the listener than the other speakers in the system.
6. High-Level Input: These inputs, also referred to as speaker level inputs, allow you to connect to the factory speaker wires. They are called High Level inputs because they convert the high voltage running through factory speaker wires to one the amplifier can handle. These inputs will provide the end user with clean, well defined sound for optimal musical enjoyment. Use the supplied cable and wire harness and connect the outputs properly as shown in the connection diagram in this manual.
7. Low Pass Filter: This control permits you to define the frequency range you want the subwoofer amplifier to receive. The subwoofer will reproduce sounds below the frequency you set.
8. Remote Level Control Port: Plug in the included remote level control to adjust the volume level of the subwoofer independently.
9. Bass Boost: This control will increase the sound level of the bass frequencies.
10. Input Gain Control: After you’ve installed your system, turn this control to minimum. Turn the head unit on (subwoofer will turn on via the remote connection) and set the volume to 2/3 full level. Slowly turn up the subwoofer input gain control until you hear a small amount of distortion. Now reduce the level until the distortion is completely gone. The input gain control is now set.
11. Power/Protect LEDs: The 2 LED’s located on the side of the amplifier panel provide indication of the unit’s status, the Power LED will light when the unit is receiving proper power, ground and remote voltages. The second LED will light when the unit goes into protection mode.
12. Thermal Protection: When the unit reaches an unsafe operating temperature of 80 degrees Celsius, the unit will turn off. Once the unit cools down to a safe temperature, it will automatically turn on again. If you live in a hot climate, we suggest installing additional cooling fans to exhaust the hot air which can build up in the trunk. This will help keep the ambient temperature in the trunk as low as possible so that your unit works flawlessly and without any musical interruption.
13. Input Overload Protection: This circuit will either shut down the unit completely or make the unit spurt on and off indicating that it is in a diagnostic condition. Turn the system off and reduce the gain on the unit or volume from your head unit. This should result in a corrected condition.
    DC Offset Protection: Should any DC voltage try to enter the unit via the speaker terminals it will cause the unit to shut down and not operate until this condition is remedied. This circuit will also protect damaging high DC voltages from reaching your speakers should your unit ever malfunction.
    PLEASE NOTE: You must reset the unit by turning it OFF and then ON again after correcting a diagnostic condition (turn your radio off and then on again). If the unit stays in protection after a reset, it is most likely faulty.

Wiring

Low Level Input
Low-level (RCA) input wiring is preferred for best audio performance. Most trunk and underseat installations will require a 6 – 12 foot RCA cable. For best audio performance be sure to use high-quality RCA cables. Be sure to run the RCA cables on the side of the vehicle opposite to the side used to carry the power and ground leads of the amplifier.

Power/Ground Wiring for Low-Level Input Configuration

1. Use an 8 gauge (or heavier) wire to connect the + 12V terminal of the amp to the positive (+) terminal of the vehicle’s battery.
2. Use a 16 gauge (or heavier) wire to connect the amp’s remote terminal to the remote output of the head unit. The unit will not turn-on if this cable is not connected. Make sure the AUTO ON button is set to the OFF position.
3. Use an 8 gauge (or heavier) wire to connect the GND terminal of the amp to the closest metal part of the vehicle’s chassis.

High Level Input
The high level inputs should only be used when your receiver lacks RCA outputs. Splice the high level input leads from the harness directly to your head unit’s speaker-level outputs. Be sure to observe polarity to avoid audio phase problems and make sure the AUTO ON button is set to the ON position.

1. Right Negative (grey/black), Right Positive (grey)
2. Left Negative (white/black), Left Positive (white)

PLEASE NOTE: The Auto Power-On feature is available only when using High Level inputs.

Power/Ground Wiring for High-Level Input Configuration

1. Use an 8 gauge (or heavier) wire to connect the + 12V terminal of the amp to the positive (+) terminal of the vehicle’s battery.
2. Do not wire the amp’s remote terminal to the remote output of the head unit. It is not needed for this configuration. Make sure the AUTO ON button is set to the ON position.
3. Use an 8 gauge (or heavier) wire to connect the GND terminal of the amp to the closest metal part of the vehicle’s chassis.
   ATTENTION Do not connect the high level and low level inputs to the amplifier at the same time!

Bass Remote
Using the included RJ12 cable, install the remote control securely under the dash or in a similar location where using it will not distract the driver.

Troubleshooting

2. Make sure the power terminal is receiving at least 12V.

3. If using RCA inputs, ensure the Remote Turn-On is receiving at least 5VDC.

4. Check the fuse and replace if necessary.

5. Make sure the Protect LED is not illuminated. If it is, turn the amplifier off and then back on.

6.   Check the Remote Turn-On switch. It should be OFF if using the RCA inputs and ON if using the high-level inputs.

Protection LED illuminates when the unit is powered on| 1. Check for short- circuits on high-level leads.

2. Turn down the head unit’s volume to prevent overdriving.

3.  Disconnect the high-level leads and reset the amplifier (turn off and then on). If the Protect LED still illuminates, the amp is faulty and needs servicing.

4. If the signal is too hot, lower the gain level.

5. Make sure the power connections are secure.

No output| 1.  Check the fuse and replace if necessary.

2.  Make sure the unit is properly grounded.

3.  Make sure the Remote Turn-On is receiving at least 5VDC.

4.  Make sure the RCA cables are properly connected.

5.  Check your high-level connections.

6.  If your head unit has a separate subwoofer output, check the settings to make sure it is enabled.

7.   Check the Remote Turn-On switch. It should be OFF if using the RCA inputs and ON if using the high-level inputs.

Low output| 1. Reset the gain control.

2. Check the crossover control settings.

3.  Power and ground cables that are too thin a gauge size for the terminals may cause low sound. Determine the proper cable gauge necessary and replace existing cables.

High hiss sound/ squealing noise is present| 1. Check for improperly grounded RCA interconnects.

2.  Check to see how your wires are run. If your RCA cables and speaker wire are run alongside your power cables, they will pick up feedback. If this is the case, you will need to run the RCA cable on the other side separate from your power cable.

3.  Noise can be picked up due to bad RCA cables. We recommend doing a test with different RCA cables. Replace the RCA cables if needed.

Distorted sound| 1.  Make sure the input level control is set to match the signal level of the head unit. Always try to set the input level as low as possible.

2.  Make sure all crossover frequencies are properly set.

3.  Check for short circuits on the high-level leads.

Amplifier gets very

hot

| 1. Make sure the wiring is correct and you are using the proper wires for your system.

2.  A poor ground cable connection can cause your amp to get very hot. Check your ground connection and make sure that the cable is securely tightened.

3.  Check the location where your amp is mounted. Make sure it is in a spot where it will receive proper ventilation.

Engine noise: static type| 1. Route your RCA cables away from the power cables.

2. Use high-quality RCA cables.

Engine noise: alternator whine| 1. Check that the RCA grounds are not shorted to the vehicle chassis.

2. Check that the head unit is properly grounded.
