Underseat subwoofer Vs Spare wheel subwoofer

Hi guys,

I precocious upgraded the speakers successful my Baleno on with 2-layer damping connected each 4 doors, the SQ accrued 1000 times compared to what banal nevertheless it inactive seems to miss the completeness of sound.

As for comparison, I person Tiago EV XZ+ which has an awesome system(Harman), I emotion getting stuck successful postulation successful Tiago vs my Baleno. The dependable is conscionable truthful overmuch implicit adjacent though it lacks the vocals.

I was considering putting a sub to implicit the fullness of sound, but I americium confused betwixt an Underseat Subwoofer and a Spare wheel(Stepney) subwoofer. I don't privation immoderate Box successful the footwear however overmuch sleeker oregon smaller it is.

My existent strategy is:

- Stock caput unit
- Polk MM6501 beforehand (Component) - Love the vocals of Polk.
- GroundZero coaxial-forgot the exemplary - Just a Filler and I deliberation an Ok One
- All 4 doors damped with 2-layer CTK metallic - This truly woke up my setup

It needs nary rattling booming sound. Just looking astatine SQ to implicit the fullness of sound.

Not capable to demo either adjacent successful Karol Bagh erstwhile I was determination past Sunday and hence beauteous confused betwixt the two.

Looking guardant to proceeding from anyone who has witnessed some and what are your thoughts.
