Filter out high frequency from 40Hz to 220 Hz that the woofer can`t play. Adjust this
knob to match the woofer`s frequency response.
The +12 Volt power cable must be connected with a fuse in line near the
terminal. Please see table 1 in page 7 to select cable and fuse.
Connect your speakers correctly which means plus to plus and minus to minus. Never
connect speaker cables with chassis ground directly. It may destroy your amplifier. We
recommend AWG 8-10# speaker cable. The two plus units and two minus units are
connected inside amplifier. The detailed connection method is shown in page 7~8.
Chassis ground terminal. The chassis ground cable must be connected very tight on a
nearby massive and electric conductive place. Please connect chassis ground near
amplifier with same gauge as power cable.
These RCA audio-inputs connect with your source unit RCA outputs. Please use car audio
RCA cables, otherwise it may be disturbed. Keep these cables as short as possible. To
avoid disturbances from your car electronics, please don`t close the existing car cables
when you install the RCA cables. If your source unit has only speaker outputs, you should
use a HIGH-LOW level adaptor.

When using the remote volume control you can adjust volume in the driver seat
conveniently.
It is the opposite of the LPF. It can filter out unwanted low frequency from 10Hz (OFF) to
50Hz. This function will increase the power handling of your woofers.
Remote terminal. The remote cable must be connected with source unit remote terminal
then amplifier will switch on and off automatically with source unit. If there are two or
more amplifiers connected to this terminal it might be necessary to add an additional
relay.
Gain control regulates the sensitivity of amplifier to match the signal output voltage of your
source unit. The gain control is not a volume adjustment. Use high quality CD music and
increase the volume of your source unit to 75%. Position the gain at the minimum and then
increase gain slowly (clockwise) .Stop at the first sign of distortion, then lower the gain a
little (counter clockwise) to achieve clear undistorted music at the maximum level.
10 BASSBOOST FREQ
11 BASSBOOST
This knob controls the boosted center frequency. The frequency can be adjusted from
30Hz to 80Hz according the specification of your car audio system. (Eg. When you adjust
this knob to 50Hz, amplifier can boost the frequency around 50Hz.) This function should
be adjusted along with
bassboost level and Q control.
This knob adjust the boost level of the bassboost center frequency. It can be adjusted
from 0 to 12dB. Combining with bassboost frequency and Q control, you can accurately
match the amplifier to subwoofer’s response.
