Fitting speakers into doors

[hatch1517]

Hi all Iwant to fit speakers into the doors of my 97 boxster have new door trims with speaker grills. Has porsche fitted the wiring as standard behind the standard none speaker door trims? If not will a later door loom with speaker wiring and door entery light fit into the door jam plug? If so is it wired to suit or can it be (dose it have vacant terminals to wire through it)?regards Peter
