I installed Kicker cs693 6x9 speakers in my 2012 Edge. ($99 at best buy) The bass is impressive with a crisp sound (without being tinny). I like them a lot!
They are rated highly here. http://carspeakerspro.com/reviews/top-rated-6x9-car-speakers/
Now be advised that these are NOT the correct size speakers for this car. I did a bit of a hack by using snips and 2" drywall screws.
They fit better in the rear. The front ones are too deep and hit a bracket in the door. They are actually mounted 1/2" proud of the intended position.
(you should put insulating material between the bracket and the speaker magnet - it can vibrate on high bass songs)
If you don't want a "hack job," don't attempt this !!!
