Some of my speakers stopped working in my car and I decided I would just change everything out.

Im looking at getting 2 pairs of Polk MMC650

and 2 pairs of Polk db1001 tweeters

Since I'm kinda new to this audio stuff. I need help finding an amp that will power all of this. Any suggestion will be helpful.
