System Configuration
The RX212S has one 4-ohm voice coil, so no series or parallel voice-coil wiring is required. Connect the subwoofer to the Z3001i as a 4-ohm load. At this impedance, the amplifier supplies 205 watts RMS to the 200-watt RMS subwoofer.
Correct amplifier gain, crossover and bass-boost adjustment is essential for reliable operation. Professional installation is recommended.
