10. Input Gain Control
Adjust the input level of the subwoofer in order to match the output level from your 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 the subwoofer, turn the input gain control to minimum.
b. On the head 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.
11. Low-Level Input (RCA Input)
Connect to the RCA outputs on your head unit. Low level input is recommended to input audio signal to the
subwoofer if RCA outputs are present on your head unit or signal processor.
12. 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 high-level input connection.
13. Remote Level Control Port
Connect to the supplied remote subwoofer level control. Use the control to adjust volume level of the
subwoofer independently.
Subwoofer Setup Procedure
1. Secure the subwoofer in your vehicle. See the section “Mounting” on page 6).
2. Disconnect the negative terminal on the vehicle battery to prevent a short circuit.
3. Connect audio 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 the 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 (GAIN) to the minimum position.
7. Reconnect the negative terminal on the vehicle battery.
8. Turn on the head unit, then the subwoofer automatically turns on.
9. Set the head unit volume to about 3/4 full level, then adjust the subwoofer’s input gain control (GAIN) to just
below the level of distortion.
10. Fine tune the various controls on the subwoofer to obtain best results.
Important notes on input level control
• The input gain control (GAIN) is designed only to adjust the input level of the subwoofer in order to match
the output level of your head 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.
