Installation
The quality of the installation will affect the system performance and
reliability. If you realize the complexity of the installation, you may wish
to contact your local authorized dealer. The amplifier is generally
mounted in the rear trunk area, but they can be mounted in any other
convenient areas such as beneath a seat.
Please be sure to locate this unit in areas with reasonable air circulation
and protection from unusual hazards. When deciding the mounting
location, it should be considered to minimize the power supply wires and
speaker wires. Minimizing the wires will provide higher audio output
from the system. It is important to ensure that the cooling fins of the
heat sink are not against a panel or surface prevention air circulation.
Mark the locations for the mounting screw holes by using the amplifier
as a template and marking the location of the four mounting holes. Drill
3.5mm diameter holes at the marked locations and install the unit on
the floor or the chassis using the supplied tapping screws.
CAUTION Before drilling or cutting any holes, investigate the layout of
your automobile thoroughly. Use caution when working near the gas
lines or hydraulic lines and electrical wiring. Please mount the amplifer
before using.

Functions
1. Power Connection Terminal
• Battery +
+12V power cable must be connected directly to the positive
terminal of the battery with an in-line protection fuse, not to the
electrical system of the car (i.e., fuse block).
• REM: Remote Turn on
Connect this terminal to the source unit’s power antenna or
remote turn on output. Some source unit’s power antenna
output disengages when a source other than the tuner is
selected. In this case, you must select a source unit’s remote
turn-on output or another switched +12V output.
• GND: Ground
When making a connection to the vehicle chassis, use the
proper size ring terminal to suit the ground cable and fasten it
to the vehicle with a threaded bolt and nut. Good grounding
forms the basis for the audio quality of the entire system. The
best solution is to connect the ground cables of all audio-
components (Radio, Amplifier, Equalizer and/or etc.) in one
common place of the vehicle’s chassis.
2. Fuse
• Used to protect the amplifier. If replacement is necessary, use
the same type. Never use a fuse with a lower or higher rating as
serious damage can occur.
3. Speaker Connection Terminal
• Used to connect the amplifier to speakers. Minimum speaker
cable size is 16 gauge.

4. Bridge Module
• Allows for the two amplifiers to be run in series and achieve
double the output into one load.
5. Power Indicate LED
• Lights blue when the power turns on.
6. Protection Indicate LED
• Lights red when the short protection operates.
7. Low Level Inputs
• These are the Low Level signal inputs and are connected to the
source unit (Radio, Crossover or Equalizer).
8.Bridged Input
• Signal input from the master amplifier in a two amplifier
bridged mode setup.
9. Bridged Output
• Signal output connected to the slave amplifier in a two amplifier
bridged mode setup.
10. Input Level Adjustment
• This input sensitivity adjustment is used to match the output
signal from the radio or source unit to the input of the
amplifier. The input section will handle a wide range of signal
voltages from 250mV to 6V. Please note following explanation:
In the min. Position (max. anticlockwise), the amplifier is the
least sensitive to input voltages, and as a result, requires a
higher input voltage: 6V. In the max. Position (max clockwise),
the opposite applies and the amplifier is the most sensitive at
250mV Therefore, if your radio has a low level signal output of
1V, the input level adjustment would be closer to the max.
position than the min. position. This is because a 1V signal is
low so the amplifier sensitivity must be fairly high. The aim is to
have the input level set to as close to the min. position as
possible, and therefore reduce unwanted noise while
maintaining the correct rated output. It is important to
remember that this adjustment is not a volume control. If the
sensitivity is set needlessly high, it may result system and
engine noise, blown speakers and damage to the amplifier may
result.
11. Bass Boost Adjustment
• Allow for up to 18dB of boost at 45Hz for the speaker outputs
when turned clockwise.
12. Variable Low Pass Filter
• Adjust from 40Hz to 250Hz with a slope of 24dB per octave.
This allows for the adjustment of the upper point of the
frequency bandwidth and the respective subwoofer.

13. Subsonic filter selection switch
• Subsonic filter ON/OFF control switch
14. Phase Switch
• Adjust the speaker phase to either 0 or 180 degrees.
15. Variable Subsonic filter frequency Adjustment
• Adjust from 15Hz to 50Hz with a slope of 24dB per octave. This
allows for the attenuation of frequencies that are mostly
inaudible and cause unnecessary strain on the amplifier.
16. Remote
• Remote Gain control connecter

Power Supply Connections
All power connections are made via a nickel-plated terminal strip at one
end of the amplifier chassis. It is highly recommended that you read the
following precautions and contact you’re nearest authorized dealer if you
are unsure of any details.
Before installations make sure the source unit (i.e., your radio in the
vehicle) power switch is in the OFF position.
Disconnect the negative (-) lead at the battery before making any
electrical connections to avoid short circuits. When making connections,
be sure that each connection is clean and secure. Insulate over your final
connections with electrical tape or shrink tubing. Failure to do so may
damage your equipment.
A secure, clean ground connection is critical to the performance of your
audio amplifier. Use the shortest ground wire possible to minimize
resistance and avoid noise problems.
Connect the amplifier’s positive (+) power lead via an external fuse
directly to the battery, as close as possible to the positive (+) terminal.
Use a rating that equals the total current consumption at full output of
all amplifiers in the system. Adding an external fuse will protect the
electrical system from short circuits that can cause a fire.
Important: Do not connect this wire to the car’s fuse panel.
Caution: Never ground the speakers to the vehicle chassis or body.

Make sure that your vehicle’s electrical system (i.e., alternator, battery,
etc.) Is capable of handling the additional load. If you are planning a
multi-amplifier system, you may need to add a second battery and
possibly upgrade the alternator with a higher output rated model.
Consult your authorized dealer for recommendations.
It is also recommended to add a digital capacitor to supplement the
vehicles battery and assist the amplifier(s)
To avoid possible noise problems, run the amplifier’s positive (+) power
lead along one side of the vehicle to the battery. Run the remote turn-on
wire and RCA audio cables down the center, and route the speaker wires
along the remaining side. If wires must cross, run them perpendicular to
each other.
When creating passage holes for the power wiring, use grommets to
eliminate any sharp edges created during drilling. This will protect the
wire from being nicked and causing a short circuit.
Extra cable can cause signal loss and act an “antenna” for noise. Use
only higher quality RCA cables that are no longer than necessary to
make a direct connection with the source unit or equalizer.
CAUTION
To begin, make +12V wire connection, secondly the ground connection
and finally the remote connection. Furthermore, the +12V wire must
always be fused as the battery and for protection against possible
damage. If you would like to replace the power fuse, replace it with a
same value shown on the surface of the fuse. Using a fuse of a different
type or rating may result a serious hazard.

CAUTION
When wiring 2 amplifiers in bridged mode to 1 speaker, connection (1) linking master
amplifier to slave amplifier must be wired first. Connection (2) must be performed next
between master and slave amplifier. Once connected, the speaker connection can be
made to the master and slave amplifier. This will achieve double the output into one
load. Any other form of connection may cause serious damage to the products or vehicle
and may not be covered under warranty. Please follow all wiring as illustrated or
contact an authorized Kaption Audio dealer.
