Low level (RCA) input is preferred for best performance. Most trunk/hatchback installations will require a 15-20 foot RCA cable, while pickup trucks and under-seat mounting will require a 6-12 foot RCA
cable. Connect an RCA cable from your receiver to the RCA input on your amplifier.
High Level Input
High level input should be used when an RCA output is not available from the receiver. Connect the speaker outputs from the receiver to the high level input connector.
Note: Only connect the low (RCA) or high level input, not both at the same time.
Connecting Other Amps
The output signal allows you to conveniently connect other amplifiers to each other.
