As all who who have Karoq without sound system (amplifier) know - the sound in our cars is dull and flat , without any more less decent bass and complete absence of high frequencies details.
I decided to fix this issue with minimal possible budget and as less technical hassle as possible. I splitted my exercise in few steps. First two I combined , but even first one will lead to way better bass in your car.
1) I did lite version of doors sound deadening included outside metal , inside metal frame, and door panel wit anti vibration and noise cancellation covers. All materials are relatively light , but effect is dramatic. I did the same with stock speakers on my previous SupMK3 and result was very good as well.
2) This time I decided not to stop on half way and installed relatively cheap Focal component speakers. Rear set was Midbass speakers from integration series IS 165VW + TWU 1.5 tweeters (original from set I lost during house move .
This tweeters fits with just a couple of drops of hot glue. Midbass are bolt on bar wires.
3) Front speakers I got Focal PS 165V1 as they do have separate crossovers for midbass and tweeters. So this saved me a hassle to reroute wiring but added additional complexity of tweeters disassembly. Both , rear and front speakers installed at default positions with original wiring ( bar connectors).
Probably PS 165FX will be better , but wiring .... I was not mentally ready
In a mean time , as I broke one of the A-Pillar plastic cover I decided to change colour to black. Maybe I can reuse old one for proper tweeters podiums one day.
The result of all this was already astonishing. For aprox 400(ish) euro + a lot of Russian swearing ( as i did all by myself) I got completely different sound in my Karoq as well as WAY less road noise during daily commutes.
But I decided to go extra mile and add Plug`n`Play AMP with DSP and under seat subwoofer
4) Apmlified DSP I got - PUZU PZ-C31. Manufacturer claiming 45W RMS. Not exactly true , but I can now listen the music way launder the with stock speakers and headunit. I definetly can recommend this Amp for everyone who want better sound in their car without rewiring and other complex exercises which can cost you thousands. Got the device here:

Wire loom actually needs to be extended , if you want underseat install.
5) Subwoofer will be Kenwood KBC-SW11 , but I do not have much info yet
Any questions , suggestions - welcome!
I am also will be happy if anyone share with me image of test disks for tuning DSP ( Pioneer have few different as example)
