AMPLIFIER INSTALLATION

INSTALLATION WARNINGS

1. Ensure the +12V lead is disconnected from the battery before you connect any new
equipment.

2. Ensure that the amplifier mounting location and holes will not interfere with the gas tank,
brake lines or electrical wiring.

3. Ensure the amplifier is securely fastened to the vehicle to prevent the amplifier moving and
causing damage in the event of an accident.

4. Ensure all wiring is protected from sharp objects and from pinching or crushing which
could result in damage to the audio system.

5. Ensure the mounting location has sufficient air flow around the amplifier. If the amplifier is
mounted in an enclosed space a 3” fan with ducting should be used to assist with cooling.

6. Do not mount any amplifier on a subwoofer enclosure as extended exposure to vibration
may cause damage to the amplifier.

7. Ensure you use the minimum recommended gauge wire/cable or larger for all amplifier
connections.

8. Appropriate mounting is very important for prolonged life expectancy of any amplifier.
Select a location that provides protection from moisture. Keep in mind that an amplifier
should never be mounted upside down. Upside down mounting will compromise heat
dissipation through the heat sink and could engage the thermal protection circuit.

CONNECTION

Ensure the audio system is turned off before making any connections to the amplifier,
speakers or source unit. Failure to do so could result in permanent damage to the audio
system.
Ensure the correct gauge cable is used for all connections; consult the cable calculator
diagram below for the correct gauge cable for your installation.

The above chart shows cable gauges to be used, if no less than a 0.5 volt drop is acceptable.
If aluminium wire is used, the gauges should be of an even larger size to compensate. Cable
gauge size calculation takes into account terminal connection resistance.

AMPLIFIER CONNECTONS

1. +12V POWER

Ensure ALL other cable connections are
completed before connecting this cable to the
battery. FUSION amplifiers should be connected
directly to the 12v battery terminal using the
appropriate gauge cable. Start at the vehicles
battery and run the cable through to the
amplifier. FUSION recommends the use of rubber
grommets when passing any cable through metal
panels to avoid sharp corners or panels that could
cut through the insulation of the cable.

PF-1802 PF-4001D PF-4004

PF-8003D PF-8001D

PF-1802

Avoid running any cables near engine components or heater cores. An inline fuse or circuit
breaker MUST be used within 30cm (12”) of your battery; this will prevent the potential risk of
a fire caused by a short in your power cable (see specifications table for recommended inline
fuse / circuit breaker ratings). Connect the other end of your power cable to the battery, but
remember to leave the fuse out or circuit breaker off until all other cable connections are
made.

2. REMOTE TURN ON

This connection turns the amplifier on and should be connected to the “Remote turn on” wire
from the Head Unit. If one is not available, a switched +12v source must be used, such as a
power antenna wire or ACC +12v.
If you are using high level (speaker) inputs and a remote turn on wire is not available, then the
amplifier “Auto Turn On” feature can be used instead of this wire. Set the “Auto Turn On” switch
to audio.

3. GROUND

Connect the Ground/Earth cable for your amplifier first. Ensure that the location is a good
source of ground (preferably the chassis / floor pan). Investigate the area you wish to use
to ensure it is free from wiring, vacuum lines, brake and fuel lines. Use either a wire brush or
sandpaper to expose bare metal, this will provide a high current contact for your ground
connection. Use the same gauge cable for the ground cable as you did for the power cable.
Secure the ground cable to the ground point with a bolt, star washer and nut. Apply some
neutral cure silicon to the bolt and bare metal to prevent possible water leaks and rust.

Connect the other end of your ground cable to the
amplifier.

4A. SPEAKER OUTPUT CONNECTION

Ensure the correct polarity is observed when
connecting speakers/subwoofers.

2 Ohm minimum speaker impedance for stereo
operation (per channel)

4 Ohm minimum speaker impedance for Bridged
operation.

4B. INTERNALLY LINKED OUTPUT (PF-8003D) ­COILS IN PARALLEL

The PF-8003D amplifier provides dual output connections for
the subwoofer to simplify wiring when using two
subwoofers or a dual voice coil subwoofer. Both positive and
negative subwoofer terminals are internally connected or
linked in parallel. For dual coil (2 x 4 Ohm) or two single coil (4
Ohm) subwoofers, connect each coil to a positive and negative
terminal. For a standard single coil subwoofer connect to
either positive and either negative terminal.

4C. BRIDGED CONNECTION (PF-1802, PF-8003D
AND PF-4004)

By connecting a speaker or subwoofer to the positive terminal
of one channel and the negative of the other channel, you are
combining the output of two channels into one. This gives you
higher output levels as noted in the specifications but you
must observe the minimum load impedance as failure to do so
will result in damage to the amplifier.

PF-8003D

LINK MODE (PF-8001D)

This allows two PF-8001D amplifiers to be bridged to produce double the output power @ 4
Ohms. Do not connect a lower impedance speaker load as this could cause damage to the
amplifier and void the products warranty. The PF-8001D amplifier must be installed and linked
with the supplied Data cable. The amplifier that has the RCA input connected from the source
(head) unit must be set to “Master”. This amplifier has control of all settings and the second
amplifier must be set to “Slave”. The subwoofer must be wired following the diagram below and
the minimum speaker impedance is 4 Ohms.
