[. . . ] Never connect an amplifier to an impedance load lower than it is rated to handle. SERIES/PARALLEL MONAURAL CONNECTION Parallel wiring for a single, dual-voice coil 4-Ohm woofer in a monaural system will result in a total impedance load of 2 Ohms at the amplifier, (See Fig. 1) if your amplifier is rated to drive 2 Ohms in bridged or one-channel operation. If each of two dual-voice coil 4-Ohm woofers are connected in parallel and then wired to 2 each other in parallel, a 1-Ohm monaural output would result (See Fig. 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. 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. 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. 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. 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).
