with superior sound quality to deliver a superb listening experience. We
have dedicated ourselves for years in order to offer the best possible
quality level and reliability in Car Audio.
It is highly recommended that a Kaption Audio authorized dealer installs
your amplifier in order to ensure the best quality sound.
Kaption Audio amplifiers can reproduce high sound pressure levels that
can cause permanent damage to the human ears. BE CAUTIOUS and
enjoy for many years.

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 area such as beneath a seat.
Please be sure to locate this unit in area with reasonable air circulation
and protection from unusual hazards. When deciding on a 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 preventing 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.

1. Protection Indicate LED
• Lights red when the short protection operates
2. Power Indicate LED
• Lights blue when the power turns on.
8. Gain control
• This control is used to match the input sensitivity of the
amplifier to the particular source unit that you are using.
9. Line In (RCA) Jacks
• These RCA input jacks are for use with source units with Low
line level outputs. A source unit with a minimum output of
250mV is required for proper operation. However, this will
accept levels up to 6Vrms.

12. 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 audiocomponents (Radio, Amplifier, Equalizer etc.) in one common
place of the vehicle’s chassis.
13. 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 different switched +12V
source.
14. Battery+ (Power Input Connection)
• This terminal is the main power input for the amplifier and
must be connected to the positive (+) terminal of the car battery.
15. Fuse
• Used to protect the amplifier. If replacement is necessary, use
the same type. Never use a fuse with a different rating as
serious damage can occur.
17. Speaker Connection Terminal
• Used to connect the amplifier to the speakers. Minimum
recommended speaker cable size is 16 gauge.
18. X-Over Switch for FULL/HP/LP
• Activates the built in electronic crossover network. This works
in conjunction with the variable X-over control.
19. By-Pass (RCA) Jacks
• RCA style output jacks allow for a signal to be sent to other
amplifier.
20. EQ Bass Control
• This equalization circuit is used to enhance the low frequency
response of the vehicle’s interior. With up to 18dB of boost
centered at 40Hz, the bass EQ can be adjusted to meet your
own personal taste.
5
21. X-over Control
• A variable X-over control having a range from 40Hz to 250Hz.
This is used in conjunction with the X-over switch in the Low
Pass or High Pass position.

Fig 3.Power Input 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.
6
Connect the amplifier’s positive (+) power lead via an external fuse
directly to the battery; the fuse must be 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.) are 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 as 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 at the battery for protection against possible damage. If
need 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
Maintaining proper impedance is critical when wiring the Class AB model amplifiers.
Improper wiring can cause server damage to both the speaker and the amplifier. Wiring
diagrams are supplied with the amplifer. If you are not sure on how to connect your
amplifer, Please contact an authorized Kaption Audio dealer before you attempt to wire
the amplifier.
