01 Park Ave rear speakers delimma

[PkAve01]

I agree that placing full range in the rear door and subs on the rear deck was a bad idea. Here is a simple but great idea. Run the signal from the rear door speakers to the rear deck and place full range 6x9 and the rear deck sub signal to the trunk and hook the signal up to a dual voice coil (DVC) sub, preferably a 10" or a 12" sub with high sensitivity. make sure your 6x9's also have high sensitivity. To bring more bass into the cabin, cut a hold in the rear deck and make a funnel to channel the port in the sub enclosure box to the underneath of the rear deck.
