Fusion Signature Series Installation Instructions Manual page 3

• You should observe the zone and polarity markings for each channel when
connecting speakers to the amplifier. For example, Z1L indicates the
ZONE 1 left channel, and Z1R indicates the ZONE 1 right channel.
• If you are connecting a combination of speakers and subwoofers to the
amplifier, you should connect the subwoofers to ZONE 2 or ZONE 4 as
illustrated below. These zones have dedicated BASS BOOST controls.
• You can connect a subwoofer to a single channel, but you should connect
it using bridge mode to get the best performance (Connecting a Speaker or
Subwoofer in Bridge Mode, page 4).
In the following example, 4 Ohm subwoofers are connected to the bridged
terminals for ZONE 2 and ZONE 4, and pairs of 4 Ohm speakers are
connected to the right and left channels for the other two zones.
In this example, you must connect the subwoofer low-level outputs from the
stereo to the ZONE 2 and ZONE 4 RCA connectors on the amplifier (using
RCA splitters), you must connect the two zone low-level outputs from the
stereo to the other two zone RCA connectors on the amplifier.
Speaker Wire Gauge Guide
You should use 16 AWG (1.31 mm
wire run is longer than 10–13 ft (3–4 m), you can use this table to determine if
you need to use a larger gauge of wire. This table accounts for terminal
connection resistance.
NOTE: If you are using aluminum or tinned wire, you should use a wire two
gauges larger than the gauge listed below to compensate for a potential
voltage drop due to the wire material.
Distance between the amplifier and
speaker
0–7 ft. (0–2 m)
7–13 ft. (2–4 m)
13–19 ft. (4–6 m)
19–22 ft. (6–7 m)
22–28 ft. (7–9 m)
Connecting Multiple Speakers or Subwoofers In Parallel
You can connect multiple speakers or subwoofers with the same impedance
rating together in parallel. When connecting speakers of the same impedance
rating in parallel, you must calculate the total impedance by dividing the
common impedance rating by the total number of speakers connected in
parallel. For example, if you connect two 4 Ohm speakers in parallel, the
resulting impedance is 2 Ohm (4 ÷ 2 = 2).
You must not connect a series of speakers with an impedance less than
2 Ohm to a single channel on the amplifier. Connecting a speaker or series of
speakers with an impedance less than 2 Ohm to a single channel may
damage the amplifier and voids your warranty.

Connect speaker wire to the positive terminal on each speaker.

Connect the wires from the positive terminals connected to all speakers in
the channel or zone to the wire connected to the negative terminal on the
amplifier .
4
Repeat this procedure for the negative terminal on the amplifier
speakers in the channel or zone.
Connecting a Speaker or Subwoofer in Bridge Mode
Connecting a speaker or subwoofer in bridge mode increases the amount of
power that can be delivered by combining two output channels together. This
is beneficial for large subwoofers that move large volumes of air and for
playing speakers louder without experiencing clipping in the audio.
A speaker connected in bridge mode must be capable of handling the
increased output power. Bridge mode can produce more than double the
output power of a single channel.
You should connect only a 4 Ohm load to the bridged terminals on a zone.
Connecting a 2 Ohm load to the bridged terminals may cause damage to the
amplifier, speaker, or subwoofer.
NOTE: When bridging the channels in a zone, you must use an RCA splitter to
send the same signal to both the left and right channels of the zone.
1
Connect speaker wire to the positive terminal of the left channel for a zone.
2
Connect speaker wire to the negative terminal of the right channel for a
zone.
NOTE: The bridged terminals for a zone are connected with a line and
labeled BRIDGED for easy identification.

Connect the other ends of the speaker wire to the positive and negative
terminals on the speaker or subwoofer.

Completing the Connections
Before you connect the amplifier to the power source, you must complete all
other connections to the amplifier .
1
Make sure all speaker wires are connected to the speakers and the
amplifier.
2
Make sure all RCA cables are connected to the amplifier and the stereo.
3
Make sure the ground cable is connected to the amplifier and the battery
(Connecting to Power, page 3).
4
Make sure the amplifier turn-on wire is connected to the amplifier and to
the amplifier turn-on wire from the stereo or a dedicated switch
(Connecting to Power, page 3).
5
Using the included 3 mm hex key, connect the power wire to the +12V
terminal on the amplifier.
