93 300D stock audio amp questions
 

I replaced the head unit and ran new wires for the dash and rear deck speakers. I would like to use the stock amp in the trunk to run the front door subs to increase the bass. Does anyone have the pinouts or a wiring diagram for the amp ?

I did find the pinouts for the amp but have one last question. Pin 7 is the control to turn it on/off, it is a small black wire. Should this be +12V or ground to turn on the amp ? I would think that it should be +12 but the black color is making me double think it.
