Connecting Multiple Speakers
If you must connect more than one speaker per channel, there are two methods in which to do so: Series or Parallel. Parallel connections are harder on the amplifier than series connections, as the total impedance is lower compared to driving a single speaker, and the amplifier must produce more current to drive them. The following diagrams show “bridged” connections from the amplifier.
