custom speaker location in full size van

i just bought a '89 full size dodge mark3 convertion van. the factory speeker location for the 6x9s in in the lower part of the front doors, and a almost blocked off by the seats. i am trying to figure out a place that i can cutom mount a set of 5 1/2 or 6 1/2 and still hear them, i cant do the kicker panels because i just dont have the room. so what ideas dose everyone have, pics would be even better

wow i totally misspelled on that last post..........sorry

if you want to take the time you can make some pods on the door panels
