each other in parallel, a 1-Ohm monaural output would result (See Fig. 2). On the
other hand, if your amplifier is rated for 4-Ohm operation in bridged or one-channel
operation, series-connect the woofer voice coils (See Fig. 3). If the amplifier is rated
for 8 Ohms, interconnect the voice coils of the woofer in series as shown to obtain an
8-Ohm monaural output (See Fig. 4).
The same applies for parallel wiring of a single, dual-voice coil 6-Ohm woofer, in
which a total impedance load of 3 Ohms will be seen at the amplifier.

wiring of each of two, dual voice-coil 4-Ohm woofers will result in a total
impedance load of 8 Ohms at each channel of the amplifier (See Fig. 5). Otherwise,
connect one woofer to each channel for 4-Ohm stereo operation (See Fig. 6), or two
parallel-wired woofers (one-per-channel) for 2-Ohm stereo operation (See Fig.7).
The same applies for series wiring of a single, dual-voice coil 6-Ohm woofer, in which
a total impedance load of 12 Ohms will be seen at the amplifier.
