Looks like the this model can handle from 60hz. So trying boosting 60-110Hz in equalizer see if it works (60-110hz should be higher than other frequency). If you want slightly more bass, you need to switch this Coaxial to backseat, then change front seat speaker to any mid-bass speaker like this one for example: MOHAWK M5-6P2 V2. But my honest opinion, you need to get proper mid-bass + tweeter set (they usually go in set). However after switching these you might feel the bass is still at somewhere else still, so this is where DSP come in play.

But I can answer some of these

-is this normal as it is budget speaker (aorund RM200++)? -> yes dont expect much

-is there any way to improve the sound quality -> in my own experience, you should be adding DSP first, then change component speakers (mid-bass) and add tweeter. This will have nice umph but DSP is costly (from 600 - few Ks). For me DSP plays really important role liking timing-phase etc but i just send my car to experts to do tuning.. they can shift the sound to somewhere else (e.g dashboard) all bass/mid/low/high can come from dashboard, definitely nice experience.
But if you want bass, just add subwoofer 10' underseat or 12'-15' subwoofer with ported box if you're bass head/or if you'd like to rattle your car (ported box = boomy sound, sealed box= tight/accurate bass)

-does the head unit play a role in this case?
For me, budget build yes, but as i progress further i skipped head unit altogether because it seems to "kacau" my audio settings/profile (I'm using TS8 4-5 years back), now I just connect audio directly to the DSP. (Digital audio player (DAP)) -> DSP) or (Phone -> DAC -> DSP).
but in short, if dont have much budget, (lower than 2K) can buy a headunit, add subwoofer, add in mid-bass to front. done.

Just need to know what you want la bro, from your post I can feel you want Sound Quality (SQ) and this is very expensive hobby.

Previously I had simple setup, Component set (midbass+tweeter), normal android headunit with internal DSP, and underseat subwoofer 10', feels sufficient already, can get within 2k including installation

It's a long and slow journey, but if you'd like to start, I recommend DSP & Component speakers first, very budget dependent bro, if you dont mind, i would like to know?

That path looks good for budget build, infinity kappa is mid-end SQ setup liao, to finish maybe need nearly 10k+ (for 3-way)
But if you feel fine with this price range:
I still feel DSP is a must in your setup because DSP functionality to control each speaker so it beam the sound to the right place like I mentioned earlier so you dont have to deal with problem you mentioned where you cannot feel the sound arrive to you.

You can talk to few other shops/installer what they think about it, especially the part where you mention the sound didn't arrive at your ears

Just to share my path
I went with this path "HU -> Component Upgrade -> + Under seat Subwoofer"

Then, last few months I upgraded my Under seat Subwoofer to 12' sealed box trunk, but I cannot feel the sub-bass arrive to my ear, it's in the car but not to me. So to fix this the installer recommended to install DSP, so I did which totally fixed this issue. So to finish off, I just recently completed 3-way active setup cross brands
Components : Adam's Digital Empire series
Subwoofer+monoamp : Infinity Primus 1270 + Primus 3000A mono
DSP : Adam's Digital 10ch Empire series

I totally haven't touched sound proofing yet, same like you I plan to DIY but haven't got time yet, but it was suggested to be done as well.
Coaxial (backseat) also I didnt change, disabled it because it messes with the 3-way setup sounds.

Some issue still retains: like how my HU (it has internal DSP) interferes with how my 3-way setup configured so I had to totally skip HU (should've went with HU with no internal DSP, so choose wisely/talk to your installer)

Also you can DM me your num if wanna discuss this faster
