NOTE: Do not connect BOTH the high level and low level inputs from your receiver to your
amplifier at the same time.
Low Level Input Wiring
Low-level (RCA) input wiring is prefered for best audio performance. Most trunk or hatchback
installations will require a 15-20 feet RCA cable, while pickup trucks and under seat installations will
require a 6-12 feet RCA cable. Always use a high quality cable.

High Level Input Wiring
Most headunits are pre-installed from the car factory and have no RCA out-put, in this case you can
use the signal from the speaker output. Connect left and right speaker wires coming from the car
stereo to the high level input as shown. Be sure to observe polarity to avoid audio phase problems.
