Hello, I have a 2014 MKZ 2.0 and yes the 3.0 engine sure has more power obviously.
It still has good response for a small engine.
Don't underestimate the power of the 2.0.
It's faster than a Yugo LOL.
From the metra adapter.
Another way is to use a 4.7uF capacitor connected to the tweeter.
It would be the POS side of the wire to the NEG side of the capacitor then the POS side of the capacitor to the POS side of the tweeter.
This way you won't need the crossover.
