I purchased the OEM rear speaker kit from a fellow PCA member. Turns out that MY2003 and later needed an additional extension cable to plug the speakers into the amp in the front hood. Later model oem kits included that extra cable. Mine didn't come with it.

Does any board member have that extra cable? You would have plugged the speakers into the back of the radio instead of the amp, and you'd have that extra harness.

You'd make my wife very happy if you'd sell me that extra cable (Boxster is Her P-car)!!
