There are two basic mounting options for your PowerBass Line Output Converter.  One is to mount the unit 
using the supplied brackets as shown in Fig 1.  Once attached, you may use the brackets as a template and 
mark the two screw locations with a felt tip pen.  Use caution to make sure there are no objects behind the 
installation surface that may become damaged during drilling.

The other option is to use a large cable or wire tie and secure it behind the dash by wrapping it around the 
chassis of the unit.  Make sure the  Line Output Converter is secure and do not let the unit hang by the wiring.  
Doing so may cause the wiring plugs to become loose and even disconnected over time due to road vibrations 
which will cause the Line Output Converter to stop working.

It is highly recommended to complete the wiring of the Line Output Converter and set the GAIN adjustment 
prior to mounting the unit.

SETUP ADJUSTMENT

GAIN Controls (Front and Rear)

Set the GAIN to increase the amount of signal coming from the Line Output Converter to your amplifier(s). Start 
with the control at the MIN position (completely counter clock wise).  Adjust the GAIN control clockwise  until 
the orange CLIP indicator begins to flicker, then back off slightly to cut distortion and operate at optimum gain.
