Using the Pre-Out jacks
Before connection: Set the POWER switches of the amplifier and Subwoofer to OFF. If they are connected with the
POWER switch(es) left ON, one or both components may be damaged.
When connecting the Subwoofer to the amplifier, be sure to always connect the "+" terminals to "+" terminals and the "–"
terminals to "–" terminals. If terminals are connected incorrectly, the amplifier may be damaged.
