Installation Cause
Be sure to carefully read and understand the instructions before attempting
to install the Amplifier.
1. Mounting Location
The mouting location and position of your amplifier will have a great effect on its ability to dissipate
the heat generated during normal operation. The design of our aluminum heatsink serves to
easily dissipate the heat generated over a wide range of operationg conditions. However, to
maximize the performance of your amplifier, care should be taken to ensure adequate ventilation.
2. Unit Installation
This section focuses on some of the vehicle considerations for installing your new amplifier.
Checking your battery and present sound system as well as pre-planning your system layout and
best wiring routes will save installation time. When deciding how to lay out your new system, be
sure that each component will be easily accessible for making adjustments.
Before beginning any installation, be sure to follow these simple rules :
1) Be sure to carefully read and underatand the instruction before attempting to install the
amplifier.
2) For safety, disconnect the negative lead from the battery prior to beginning the installation.
3) For easier assembly, we suggest you run all wires prior to mounting your amplifier in place.
4) Route all of the RCA cables close together and away from any high current wires.
5) Use high quality connectors for a reliable installation and to minimize signal or power loss.
6) Think before you drill! Be careful not to cut or drill into gas tanks, fuel lines, brake or
hydraulic lines, vacuum lines or electrical wiring when working on any vehicle.
7) Never run wires underneath the vehicle. Running the wires inside the vehicle provides the
best protection.
8) Avoid running wires over or through sharp edges. Use rubber or plastic gromments to protect
any wires routed through metal, especially the firewall.
9) ALWAYS protect the battery and electrical system from damage with proper fusing. Install
the appropriate fuseholder and fuse on the +12V power wire within 18" (45.7cm) of the
battery terminal.
10) When grounding to the chassis of the vehicle, scrape all paint from the metal to ensure a
good, clean ground connection. Grounding connections should be as short as possible and
always be connected to metal that is welded to the main body, or chassis, of the vehicle.

(2) HIGH LEVEL INPUT : This allow connection to any head unit that has no RCA output via the use of the high level speaker wires.
In the picture to the left you will see an enlarged drawing of the high level input connector. When connecting a head unit to the amplifier ensure
that you connect the GND wire to the chassis of the vehicle and connect the head units speaker connections to the appropriate connection.
(3) BASS BOOST : This is a variable control to increase the bass boost at 45Hz, adjust to suit.
This output is a selectable by the Crossover Selector switch
(4) HIGH PASS : Set the crossover switch (7) to high pass and turn this control to 65Hz when using speaker's smaller than 6 x 9".
NOTE : Failure to do so could result in speaker damage.
(5) LOW PASS : Set the crossover switch (7) to low pass when a subwoofer is connected. Ensure th crossover frequency is set at 100Hz or
below. NOTE : Failure to do so could result in speaker damage.
(6) LEVEL : This allows level adjustment of the input signal. Use this control to correctly match the head unit to the amplifier.
To set this control correctoly, turn the amplifier level to MIN and the head unit to 3/4 volume, with the BASS and TREBLE on zero, then slowly
turn up the amplifier level control (6) towards the MAX end of the control. NOTE : If the sound becomes distorted, turn this control down.
(7) CROSSOVER SELECTOR : Set the apporpriate mode of operation. The 3 positions available are FLAT, HIGH PASS and LOW PASS.
(8) POWER LED : When illuminated the amplifier is turned on.
(9) PROTECTION LED : When illuminated it indicates a fault has occurred. Check installation.
(10) FUSE : Please ensure correct type of fuse if fitted, as specified in this manual.
(11) +12V : This must be connected directly to the vehicle batterie's positive(+) terminal via an inline fuse at the battery end. NOTE : This is
to be the last wire to hook up during installation as damage could result.
(12) REMOTE : This terminal is for turning the amplifier on and off. This requires a requires a switched positive (+12V) to power "on" the
amplifier, this can be found on the rear of the head unit in the form of a electric antenna output, or a remote on output. Of not available you
can wire to the ACC position on the key.
(13) GROUND : Connect directly to the vehicle's chassis.
NOTE : This is to be the first wire to hook up during installation as damage sould result.

The above chart shows cable gauges to be used, if no less than a 0.5 volt drop is acceptable. If aluminum wire or tinned wire is used, the gauges
sould be of an even larger size to compensate. Cable gauge size calculation takes into account terminal connection resistance. 1 Metre = 3.28 Feet
