1. Low level input
For connection to any source (head unit) with a low level output. This is your RCA output from the source (headunit)
2. Slave input / output
RCA input and output Connections used for amplifier strapping
3. High level input
To be used when no RCA's are available. Use the provided loom and connect to the closest speaker. The loom connector will only fit one
way around. Once plugged in you should connect the wires as below:
Left Positive – L+ white Right Positive - R+ Grey
Left Negative - L- white / Black Right Negative - R- Grey / Black
