CONTROL FUNCTIONS
1. SPEAKERS
Connect speakers/subwoofers to these terminals. Be sure to check wire for proper polarity.
Never connect the speaker cables to chassis ground.
2. +12 Volt Power
Connect this terminal through a FUSE or CIRCUIT BREAKER to the posive terminal of the
vehicle baery or the posive terminal of an isolated audio system baery.
Warning: Always protect this power cable by installing a fuse or circuit breaker of the appropriate
size within 18 inches (45cm) of the baery terminal connecon.
3.Remote Turn On
This terminal turns on the amplifier when (+)12 volt is applied to it . Connect it to the remote
turn on lead of the head unit or signal source.
4.GND
Connect this cable directly to the frame of the vehicle. Make sure the metal frame has been
stripped of all paint down to the bare metal. Use the shortest distance possible. It is always a good
idea to replace the factory ground at this me with a larger cable equal to the new amplifier power
cable or larger. CAUTION: Do not connect this terminal directly to the vehicle baery ground
terminal or any other factory ground points.
5. RCA input jacks
These RCA input jacks are for use with source units that have RCA outputs. A source unit with
a minimum level of 200mV is required for proper operaon. The use of high quality twisted pair
cables is recommended to decrease the possibility of radiated noise entering the system.
6. REMOTE
Connect the remote controller to control the subwoofer amplifier volume from the driver
seat locaon, for ease of adjustment during playing.
7. Gain Control
The Gain control will match the amplifiers sensivity to the source units signal voltage. The
Operang range is 5V to 200mV. This is NOT a volume control!
8. Low Pass Filter Control (Mono block)
This control is used to select the desired low pass x-over frequency. The frequency can be
adjusted from 40Hz to 220Hz for all bass mono models.
9. Subsonic Filter Control (Mono block)
This control can filter out unwanted low frequency from 10Hz (OFF) to 50Hz. This funcon
will increase the power handling of your woofers.
10. Bass Boost Level switch (Mono block)
This switch can boost bass level by 0dB, 6dB or 12dB. The boost frequency is centered at
50Hz.

EXCURSION

11. Hi-pass filter (Full range)
This knob controls the frequencies played for the front channels. Low frequencies can be cut
out from OFF to 200Hz. At OFF posion, none low frequency cut out, that means full pass.
12. X-over mode and frequency Control (Full range)
These controls allow control over the frequencies played for the rear channels. There is an
opon for Low Pass, Full Range or High Pass. In LP or HP mode, the crossover frequency can be
tuned from 20Hz to 250Hz by the frequency knob.
13. Power Indicator
This LED will light up when amplifier works properly.
14. Protecon Indicator
The red LED will light up and will be flashing if there is a fault presented to the amplifier.
Please disconnect the amplifier and resolve the fault before reconnecng the amplifier.

INSTALLATION PRECAUTIONS
Before you install the amplifier, invesgate your car's layout very carefully. Take special care
when you work near the gas tank, fuel lines, hydraulic lines and electrical wiring. Before making
or breaking power connecons in your system, disconnect the vehicle baery. Confirm that
your head unit or other equipment is turned off while connecng the input jacks and speaker
terminals. If you need to replace the power fuse, replace it only with a fuse idencal to that
suggested by this manual. Using a fuse of a different type or rang may result in damage to your
audio system or your amplifier which is not covered by warranty .
CONNECTING THE AMPLIFIER
1. Select cable and fuse according to the following table.
2. Connect the amplifiers ground cable to a close, bare metal part of the frame or chassis.
Use a nut and bolt, NOT a screw! The ground cable must be at least the same size as the +12volt
cable.
3. Connect the remote terminal to remote output of the head unit using 16 gauge (or heavier)
wire.
4. Connect the fuse holder within 15”(30cm) of the car baery, and run the selected cable
from this fuse to the amplifier.
5. Connect all the inputs with high-quality cables. Connect Remote Control if necessary.
6. Insert fuse(s) into the baery fuse holder(s).
7. If using the rear channel of the HXA45 for a subwoofer, bridge the channels by using the
Le “+” and the Right “-“ terminals.
