You will have to make an enclosure that will be suspended from the rear dash or make one where the ports protrude outside of the box and extend into the rear dash area. Another thing to watch out for is if you have a vehicle without trunk lifts ( only trunk cross beams ) then you have to accomodate the crossbeams into the design. How many subs are you installing and what size are they ? What year, make & model vehicle is this ?

I think those vehicles have shocks for the trunk lid so the rear deck is free for an enclsoure to be mounted straight to the deck. The most time consuming this is getting those damn factory speakers out of the dash. YOu have to take out the rear seat to do it and it's a pain in the @$$ !! Once the rear speakers are removed, you will have to build yourself a new back dash to cover up the speaker holes and show off the new port holes.
