Series-Parallel - Four Speakers (dual 4 Ohm voice coils)
Note: Verify and ensure that the woofer wiring is connected as shown with the
negative connection from the first woofer coil connected to the positive connection
of the second woofer coil.
Four dual 4 ohm voice coil woofers should be wired with the voice coils on each
woofer in series and then parallel the four woofers for a resulting a 2 ohm load to the
amplifier.
