Amplifier
Outputs

The con nec tion of more than one 

speaker per channel will tend to 
de grade the speaker’s frequency 
response, and may make the ampli

Þ

 er 

run hot. For the best results use one 
speaker per chan nel.

If you do want to con nect more than 

one speak er per channel, there are 
two main ways: Series or Parallel.

Series

For example, if you want to              

series-connect two speak ers to the 
front right channel of the ampli

Þ

 er: 

•    The positive output terminal of 

the right channel con nects to 
the positive input post of the 

Þ

 rst speak er.

•    The negative input post of the 

Þ

 rst speaker connects to the 

positive input post of the sec-
ond speaker.

•    The negative input post of the 

second speaker connects to 
the negative output terminal of 
the right channel.

•    The total impedance of speak-

ers in series is found by adding 
their im ped anc es together. For 
example, two four ohm speak-
ers in series is an eight ohm 
load. 

•    Series connections are easier 

on the ampli

Þ

 er than parallel 

connections as the total imped-
ance is higher than driving a 
single speaker.

Parallel

For example, if you want to parallel-

connect two speak ers to the front right 
chan nel of the ampli

Þ

 er: 

•    The positive output terminal of 

the right channel con nects to 
the positive input post of the 

Þ

 rst speaker and to the positive 

post of the second speaker.

•    The negative output terminal 

of the right channel con nects 
to the negative input post of 
the 

Þ

 rst speaker and to the 

negative post of the second 
speaker.

•    The total impedance of equal 

speak ers in parallel is found 
by dividing the impedance of 
one speaker by the number of 
speakers. For example, two 
eight ohm speakers in parallel 
is a four ohm load (eight ohms 
divided by two), four eight ohm 
speak ers in parallel is a two 
ohm load (eight ohms divided 
by four). 

•    Parallel connections are harder 

on the ampli

Þ

 er than series 

connections, as the total im-
pedance is lower com pared to 
driving a single speaker, and 
the ampli

Þ

 er must produce 

more current to drive them.

•    Ideally, the total average 

impedance should be no less 
than 2 ohms per channel.

•    You must make sure that the 

lower impedance does not 
cause the am pli 

Þ

  er to over-

heat, shut down, blow the line 
fuse, or pop your circuit break-
er. If this hap pens, you should 
reduce the number of speakers 
wired in parallel, rewire them in 
series, or use more than one 
power ampli

Þ

 er.
