I have the shaker in 2014 V6. I replaced the ford speakers with Infinity 6832's all around. I did the doors and had the backs done. This alone improved the sound greatly. I also ordered a 100w Bazooka 6.5" powered tube. That should let me dial down the 'shaker bass' and perserve the the factory amp and subs.
The guys that did the rears, were saying to go any more would require an amp (possibly a JL 700/5 4 x 100 & 1 x 300 - 2ohm stable). With your car you could put a sub in the trunk and amp a 4 speaker, in mine I'd probably put the Kicker 8" replacements in the doors and run those in a parallel 2 ohm load.
