• The amplifier supports a nominal 4 Ohm speaker load impedance, and a 2 Ohm minimum speaker load
impedance.
• When connecting a subwoofer, you should use 12 AWG (3 through 4 mm
wire.
• You must connect a 1-channel RCA cable from the subwoofer line out port on the stereo to the single-RCA
input port on the amplifier.
