Infinity Reference 6030cs vs Alpine SPS-610C vs Polk Audio db6501

Thoughts and opinions other than "bite the built and spend a grand" appreciated! Whats the the stock RES & RBZ head units power rating?
I have had experience with the polk components and powering them with the factory head unit in an VW passat I owned.
I mounted the crossovers behind the door panels, I did some test fitting to make sure nothing interfered.
I used this set up for over a year before I powered the same speakers with an amp and upgraded aftermarket head unit.
I also used a set of low end coaxial infinty speakers in previous grand cherokee we owned.
Based on the specs of these speakers you are comparing I would consider the Polks or the infinity first before I chose the Alpines.
The reason for this is the frequency response on the speakers.
If you will just be upgrading the speakers and keeping the headunit then the polk and infinity hit lower frequencies than the alplnes.
I would go with the alpine I were adding a subwoofer so that I could cover the range that the alpinee don't down on the low end.
mind you now this is only based on the specs you posted since I have never used any alpine speakers.
