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.
Avoid running any cables near engine components or heater cores. An in line 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 in
line 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
“Auto Turn-On” switch must be set 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.
