You should install RT app or EQ spectrum meter on you phone or Ipad to check the frequency with pink noise to see the frequency from each or front/back speakers. I think IPAD have much better mic.
The settings I gave has tune down abit of bass to allow the speakers to give better clarity and also leave some of the low freq to active subwoofer to do the work.
You can try adjust freq 50hz to 200 hz range to high to give your more bass. You can try with rear speakers first and the slow adjust for front too.
I tried before that you can get really good bass from this, but sacrifying high end freq. and abit of clarity.
The active subwoofer that I'm having is Blaupunkt GTR-130.
Got it at RM405 via shoppee.

It is pulling a (+) directly from battery to active subwoofer. Then ACC/remote coming from PnP socket for DSP.
No wire cutting involved here, however question void warranty is very idiotic subjective matter for Proton.
At least I do have the option to remove if I needed.
Now you make my heart itchy 😂 so total DSP + Active Sub + installation I assume you spent around 1.3K ?
