Right amp for speakers... Plz help
 

I got a 2011 civic si and I'm trying to change all 4 speakers excluding tweeters and sub for now.

I have in plan some Alpine sps-600 because they have good reviews and I tried them and I liked the sound.

MY QUESTION IS: WHAT KINDA OF 4 CH AMP WILL DO THE JOB TO MAKE THE SPEAKERS WORK IT'S BEST?
Here are the specifications for the speakers. Any help will be apreciated. Also if anyone know where to find a post with pics on how to replace the front and rear speakers. Thank you.
