other in parallel, a 0.5-Ohm monaural output would result (See Fig. 2). On the other hand, if your amplifier is rated for 2-Ohm operation in bridged or one-channel operation, series-connect the woofer voice coils (See Fig. 3). If the amplifier is rated for 4 Ohms, interconnect the voice coils of the woofer in series as shown to obtain an 4-Ohm mon- aural output (See Fig. 4).

SERIES/PARALLEL STEREO CONNECTION

Series wiring of each of two, dual voice-coil 2 Ohm woofers will result in a total impedance load of 4 Ohms at each channel of the amplifier (See Fig. 5). Otherwise, connect one woofer to each channel for 2 Ohm stereo operation (See Fig. 6), or two parallel-wired woofers (one-per-channel) for 1-Ohm stereo operation (See Fig.7).
