Need help with speaker and amp combo

[supbrosef]

So i am in the market to upgrade my stock speakers. I need help choosing the proper combo and would like some feedback.

These are the conditions

~$600 budget

-Looking at buying everything new

-Prefer focal for the components

-4 channel amp(class a/b)

These are the two sets i have been looking at.

Amazon.com : Focal PS 165 6.5" 2-Way Component Speakers : Component Vehicle Speakers : Electronics

Am i cheaping out on the amp too much? I want the best sounding possible. Would like some help trying to find the best possible combination. Thanks for your help //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
