Audiovox PSW-12DC, PSW-10DC manual Series/Parallel Stereo Connection, Mono

two dual-voice coil 4-Ohm woofers are connected in parallel and then wired to 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 8-Ohm monaural output (See Fig. 4).

SERIES/PARALLEL STEREO CONNECTION

Series 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).
