Connect the speaker terminals of each amplifier to any combination of one or more subwoofers that results in nominal impedance between one and four ohms. Make sure that each amplifier sees the same speaker impedance. W WWA AAR RRN NNI IIN NNG GG: ::The amplifier’s gain control is bypassed completely in SLAVE mode.

Use the following speaker connection diagram when connecting the subwoofers to the amplifiers. Connect the amplifiers speaker terminals to any combination of one or more subwoofers that results in a nominal impedance between 2 and 4 ohms. DO NOT connect loads of less than 2 ohms when connecting to amplifiers in the External Synced Bridged combination. W WWA AAR RRN NNI IIN NNG GG: ::Two wires of 12AWG minimum must be connected between the negative sub out terminals of the master and slave amplifiers.
