Sound Upgrade recommendations

Guys, I just bought my new 3-door Jimny last week and the speakers that came with it totally suck.

I’m planning to change them and have sort of gotten authorization from the dealer, but they told me to be careful not to mess with the electrical system (no extra wiring or power amps installed) so I don’t lose the warranty. They did confirm I can upgrade the stock speakers.

I’d love to hear your thoughts on recommended brands and models. I really love good audio — not necessarily super loud (though decent volume matters for personal use) — but clarity and frequency definition are key for me.

Thanks in advance, fellas 🫰🏻🫶
