Connecting Multiple Speakers or Subwoofers In Parallel
You can connect multiple speakers or subwoofers with the same impedance rating, model number, and type them 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).
NOTICE
You must not connect a series of speakers with an impedance less than 2 Ohm to a single channel on the amplifier. Do not connect more than two speakers in parallel per zone
output.
1. Connect the speaker wire to 1 the positive terminal for channel or zone on the amplifier.
2. Connect the speaker wire to the positive terminal on each speaker.
3. Connect the wires from the positive terminals on both speakers in the channel or zone to the wire connected to the positive terminal on the amplifier.
4. Repeat this procedure for the negative terminal on amplifier 2 and both 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.
NOTICE
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.
¹Fusion speaker cable is sold in various lengths. See your FUSION® dealer for more information.
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 the speaker wire to the amplifier’s positive terminal of the left channel for zone 1.
2. Connect the other end of the speaker wire to the positive terminal on the speaker or subwoofer 2.
NOTE: The bridged terminals for a zone are connected with a line and labeled BRIDGED for easy identification.
3. Connect the speaker wire to the negative terminal of the right channel for zone 3.
4. Connect the other end of the speaker wire to the negative terminal on the speaker or subwoofer 4.
5. Connect the split ends of an RCA splitter to the left RCA ports for both bridged zones on amplifier 5.
6. Connect the single end of the RCA splitter to the left RCA stereo output 6.
7. Connect the split ends of an RCA splitter to the right RCA ports for both bridged zones on amplifier 7.
8. Connect the single end of the RCA splitter to the right RCA stereo output 8.
