just trying to add subwoofers to my stock stuff

 

Where are you tying in the LOC. Between the Headunit and the Amp or between the AMP and the speakers. Which ever way your trying you could try the opposite. I believe the Bose headunit uses speaker level output to the amp.

 

i hooked up the wires in your diagram. the lt grn and dk grn and the gry and tan. the loc has a ground and i grounded it to the shifter mount and nothing happend. i couldnt tell you if its before or after the amp.
