COMBINATION OF SERIES & PARALLEL
This is really just two sets of Series wired speakers connected in Parallel. This is how you maintain a consistent
load with multiple speakers. The importance of this is more evident when you have more than one cabinet
to connect to your amplifier. This is when you need to figure out the loads and how to wire them up without
applying too low of a resistance on the amplifier.
Simply connect the Positive side of Speaker A to the Positive side of Speaker C.
Connect the Negative side of Speaker A to the Positive side of Speaker B. Next, connect the Negative side of
Speaker C to the Positive side of Speaker D.
And lastly, connect the Negative side of Speaker B to the Negative side of Speaker D.
4 Eight ( 8 ) Ohm speakers wired in Series Parallel = a Total Load of 8 Ohms.
