    Front Speaker (in doors) 6.5″ (Infinity Reference 6032si works very well)
    Rear Speakers (in Columns) 4″ x 6″ (Infinity Reference 6432cf 4 x 6-Inch far out perform factory OEMs)

    @ Michael – That maybe the power antenna trigger. A volt/ohm meter can be used to see if it get a shot of power at on/off cycle which should verify. I believe that’s what the antenna is looking for as it’s switch.

    Also, what is the small connector block next to the main connector block? Is that for remote cd changer?
