Hi all, would like to get opinion for this setup

My ride: myvi 2012 Se
Prefers SQ/SPL/SQL: SQL
File format/medium used for my source: usb or Bluetooth (Spotify)
Music genre: jazz

Rate this setup maybe?
Amp : Kenwood KAC PS704EX (70RMS X 4)
Front : Hertz DSK 165.3 (80W RMS)
Rear : Hertz ECX 165.5 (70W RMS)
HU :android 2 GB + 16Gb (nothing fancy)
DSP : Audxeon D1600 6 channel DSP

Will do custom fibreglass casing for front 6.5" speaker + run new wires from amp to each speaker with tweeter to occupy space from current 4" slot on dashboard + soundproof (door panel, flooring, roof, wheel arch, car boot)

Is it ok or can I go for another brand for speakers? Generally looking into using something compatible with the amp since bought already haha.
