PARALLEL:
When wiring in parallel, the resistance of the speakers decreases. Two 8 ohm speakers wired in (hooked-up) Parallel
results in a 4 ohm load. It's easy to calculate the effect of a resistive load when all the speakers are all the same resistance. It is really
not suggested to wire different resistive load values in Parallel (8 and 4, 16 and 8 etc.) The formula for figuring the total impedance in
Parallel is the multiplication of the two loads divided by the sum of the two loads - i.e. putting two 8 ohm speakers in Parallel results
in a 4 ohm load. Connect the Positive side of Speaker A to the Positive side of Speaker B - Connect the Negative side of Speaker
A to the Negative side of Speaker B.
COMBINATION OF SERIES & PARALLEL:
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.
This is really just two sets of Series wired speakers connected in Parallel. This
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 Neg-
ative side of Speaker D.
4 Eight (8) Ohm speakers wired in Series Parallel = a Total
Load of 8 Ohms.
