1. Power and High Level Audio Input Connector:
This (6)-Pin connector provides battery power, chassis ground and 2 channel
speaker level input to the LS-SUB-75. Follow the enclosed wiring diagrams for
correct connection.
2. RCA Line Inputs:
These (2) RCA type plugs are for the connection of the Left and Right channel
Line-Output provided by the radio system. These connections are preferred and
should be used if the audio source has the line-out feature.
3. Input Sensitivity Control:
This knob is used to adjust the audio input (6-Pin connector input or line level
input) level as needed for best input matching and proper performance.
4. Low-Pass Crossover Frequency Selector:
The selector switch controls the amount of high frequency that will play from the
woofer. The lower settings prevent less high frequency output and "full-pass"
does not block any high frequency. Adjust to best sound quality.
