High Level Input Wiring
The high level input(s) should only be used when your head unit lacks RCA outputs. If the RCA outputs are not present, connect the speaker outputs from the receiver to the high level input connector of the amplifier. Be sure to observe polarity to avoid audio phase problems.
NOTE: Do not connect BOTH the high level and low level inputs from your receiver to your amplifier at the same time!
