1. Ground Terminal
Connect to the closest point on the chassis of your vehicle.
2. Remote Terminal
Connect to the remote output wire of your head unit. No need to make the remote connection if you use
high-level input connection and auto power on function is activated.
3. Battery Power Terminal
Connect to the positive terminal of the 12V vehicle battery.
4. Fuse Holder
Insert a 20A 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.
5. 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 to input
overload, short circuit or high temperature.
6. Phase Control
Press to adjust bass response (no or little bass sound) caused by time alignment in your 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.
7. Auto Power On
This function works only with high level input connection, and make sure the remote wire is not connected
at the remote terminal on the subwoofer.
Press ON or OFF switch to activate or deactivate the function. If activated, the subwoofer will automatically
power on or off whenever your head unit is turned on or off.
8. Low Pass Filter (LPF)
Use this control to define 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 only to receive lower frequency signal.
9. Bass Boost Control
Use this control to increase sound output level in bass frequencies.
