Question about Car Audio & Video
I assume you want the sub and amp for listening to music and not the onstar itself, just the vehicle has onstar? if thats the case the easiest way would be to hook a line level converter into the rear speaker wires (both right and left) this gives you a RCA jack output to connest your rca cables to to send signal back to the amp. run power to the amp as described in the wiring kit directions and hook everything up as the amp requires. the rca cables would go to the "in" on the amp and you can adjust the line level converter for output voltage ( increasing the level increases the volume before the amp, so be easy on the adjustments or you could blow your speakers.)
