Replacing stock speakers, Need Opinions

[Pashody]

I am having a shop change out my stock speakers to Focal 165A1 6.5" comp spkr for the front and Focal 165CA1 6.5" coax spkr for the rear doors.

Need some opinions to help me justify that this is worth it.

Good but basic speakers.
What head unit & amplification are you using with them?

I'm thinking an Alpine MRX V70 5ch haven't picked a new head unit, still running the stock symphony II [:(]
