Wingdreamer

Just installed Sound Dynamic tweets in the A pillars in my truck. Running the stock, upgraded sound system (non- Sony) and need to wire in these tweets by the kick panels on each side. I realize that the speaker wiring goes through each rubber boot into each of the front doors to connect to the existing front door speakers. I would like to tap into the speaker wiring at each kick panel before they go into the boot to the door. Does anyone know what the wires are that go to each door and where (near the kicks) that I can tap into?
