SPEAKER LOAD
Keep in mind FUSION PowerPlant Amplifier series are high power amplifiers and not high
current amplifiers. In other words, they require a minimum impedance of 2 ohms STEREO and
4 ohms bridged MONO to operate trouble free. Too low of impedance could send your FUSION
amplifier into protection mode and/or damage the amplifier.
SPEAKER WIRING
Choose the correct speaker wire for your application. Most applications will require a minimum
of 16 gauge. Route the speaker wire taking the same precautions you took when you ran the
power cables. Terminate these wires at the speaker end by using insulated speaker terminals
(not supplied) or by soldering the connection. Make sure the speaker connections are positive to
positive and negative to negative. At the amplifier end, use a Hex type screwdriver to loosen the
speaker terminals on the amplifier. Connect the speaker wires and tighten the screws securely.
Check to make sure you’ve maintained proper polarity and balance.
SPEAKER TERMINAL BLOCK
REMOTE TURN-ON
This terminal must be connected to a switched +12V source. Typically, remote turn-on leads
are provided at the headunit which will turn the amplifier on and off in correspondence with the
source. If the head unit does not have a remote turn-on lead, then a power antenna wire can be
used. If neither of these leads are present on the head unit then a switched +12V supply must
be used, like the ACC +12V.
Run a minimum of 18 gauge wire from the amplifier location to the source of the switched +12V
lead. If possible, route this wire on the same side of the vehicle as your power cable. Connect the
source remote output to the wire. Go back to the amplifier and cut the wire to length. Loosen the
screw terminal marked REM on the amplifier using a Hex Phillips type screwdriver. Slip the wire
into the connector and tighten the screw securely.
