WIRING

LOW LEVEL INPUT WIRING

Low-level (RCA) input wiring is preferred for best audio performance. Most trunk and under-seat 
installations will require a 6-12 feet RCA cable. Always use a high quality cable.

POWER CONNECTIONS

Connect the ground terminal to the closest point on the chassis of the vehicle. Use 8 gauge (or 
heavier) wire to connect the ground cable.

Connect the remote terminal to the remote output of head unit using 16 gauge ( or heavier ) 
wire.

Connect an empty fuse holder within 16" (40 cm) of the car battery, and run 8 gauge (or heavier) 
cable from this fuse to the amplifier location. Then connect the fuse holder to the "BATT+" (+12V) 
connection on the subwoofer rear panel.

NOTE: Do not connect both the high level and low level inputs from your receiver to your amplifier 
at the same time!
