How is this setup?

So in 2 weeks I’m getting a system installed to my 2017 Impala. I told the guy right away I’m not trying to shake every bolt off my car, just want something nice but with a little knock. After giving him my price range and what I’m looking for, he told me to buy this. Amp is a sundown 600 and Sub is a sundown E12 v4. Is this a good setup?

(I had a system in my 03 lancer in highschool but I don’t know really anything about sound systems, watts, etc..)
