Speaker connection diagrams
– Below are three diagrams that illustrate how to connect speakers
and/or subwoofers to the amplifier in different combinations. The speakers named “left” or ”right” can be
full range speakers or component speakers. In the event of component speakers being connected, it is
the crossover that the + and – of the channel connect to. These are illustrated on the output
connections of a 4-channel model.
Two 4 ohm subwoofers can be connected to the subwoofer channel on the 5-channel model, c
on both subwoofers to the + on the subwoofer channel, and connect – on both subwoofers to the –
subwoofer channel.
In the event that two extremely high power component speakers are to be connected to the amplifier
(either 4-channel or 5-channel models) that require the amplifier to operate in dual bridge 2-channel
stereo mode (one left output and one right output), specific connections must be made, as detailed
below.

The input from the source unit must come in the form of an RCA pair (one
left and one right). The left RCA plug is connected to the input socket of one
of the supplied adaptors. The plugs on the adaptor are then placed onto the
“Channel-A” input sockets. It may be a tight fit, but the adaptor will be
securely held when pushed into place. This means that “Channel-A” is now
the left input/output side of the amplifier. The right RCA plug is connected to
the input socket of the other supplied adaptor. The plugs on the adaptor are
then placed onto the “Channel-B” input sockets. This means that “Channel-
B” is now the right input/output side of the amplifier. This is illustrated in
the diagram above this text.
Ensure that the 2ch/4ch switch is set to 4-ch (not pressed in).
The crossover connecting the left speakers connects to the Channel A bridge
output, and the crossover connecting the right speakers connects to the
Channel B bridge output. This is illustrated in the diagram to the right of this
text.

Power connection/RCA connection diagrams -
Below is a diagram of the basic completed installation
of the power cables and RCA leads on the amplifier. The speaker connection diagrams follow on the next
page.
There are no RCA/phono outputs on the 4-channel or 5-channel models. RCA outputs on an amplifier enable
a phono lead to be used to connect the RCA output on one amplifier to the RCA input
on another amplifier. This can be useful in situations where only one
RCA output from the source unit is available.
Two phono splitter leads (or “Y” leads) have been included with the
amplifier to allow another amplifier to share the same RCA output
from the source unit if required. The leads convert one RCA socket
on the “L” input of the amplifier, into two RCA sockets, and convert
one RCA socket on the “R” input of the amplifier into two RCA
sockets, as illustrated in the diagram to the right of this text.
Installation
OWNER’S MANUAL
Mounting Instructions
Before mounting, please read the “Installation” section. The best place to mount the amplifier is
somewhere where it will not get damaged, eg. by items in the boot of the vehicle. The amplifier
dissipates heat using its heat sink; somewhere with sufficient space and air would be fine. Therefore
placing the amplifier in between items, placing items on top of it, or mounting it upside down is not
advisable. This amplifier must be installed horizontally (flat – facing the sky) with plenty of air around it,
or the amplifier may be in serious risk of damage. Examples of surfaces to mount on are the floor of the
boot or fake floor of boot (MDF). Never mount the amplifier on its side. Never mount the amplifier onto
a subwoofer box as this can damage the amplifier. Never mount the amplifier outside of the car, in the
engine bay or anywhere where it has a risk of getting wet. Normally it is best to attach the amplifier to a
board, and then attach the board to the car body. This is good practice to avoid noise problems.
Before mounting, make sure that the surface is suitable and free from any obstructions. Use the
amplifier as a template and mark where the holes are to be drilled with a pencil or pen. Drill the pilot
holes with a drill bit of diameter smaller than that of the screws. Then place the amplifier on the surface
and tighten the screws until they are holding the amplifier securely in place.
