Upgrading the Audio Experience in Your Hyundai Creta

The Hyundai Creta is a fantastic compact SUV, but let's be honest, the stock audio system can leave a bit to be desired for music lovers like myself. I'm looking to crank up the sound quality in my Creta SX 0 (the new night sky blue paint is amazing, by the way!) and wanted to see what my fellow Creta enthusiasts have done.

Current Setup:

Hyundai Creta SX 0 (stock audio system)
Looking for ways to improve sound clarity, bass response, and overall listening experience.
Upgrade Options:

Speaker Swap: Replacing the stock speakers with higher quality aftermarket options seems like a popular choice. Any recommendations for speaker brands or specific models that work well in the Creta? Coaxial or component speakers – what are the pros and cons for the Creta?
Amp It Up: Adding an aftermarket amplifier could provide more power and potentially improve sound quality. Is this a DIY project, or is professional installation recommended? What are some things to consider when choosing an amp for the Creta?
Subwoofer Bliss: For those deep bass notes, a subwoofer installation could be the answer. Is a powered subwoofer or a separate amp and enclosure setup a better option for the Creta's cargo space? Any recommendations on compact subwoofers that fit well and deliver great sound?
Infotainment Integration: How well do aftermarket audio components integrate with the Creta's infotainment system? Are there any compatibility concerns to keep in mind?
Open to Suggestions:

Beyond the options mentioned above, are there any other audio upgrades Creta owners recommend? Sound deadening, DSPs, or other tweaks?
Any general advice or lessons learned from your own Creta audio system modifications? Installation tips, soundproofing recommendations, or even places to avoid – all info is welcome!
