You need SQ then. I don't drive Preve but here is what I did on my old proton's HU to work to desired level:
1. Used old school Blaupunkt 4ch amp. RM150.
2. Half cut Blaupunkt speaker. RM90
3. Cables + installation. RM70.

I choose 4ch amp over the component speaker as it allow for wider future upgrade which never happened till I passed my ride to my other half.
Component speaker is definitely cheaper as you can DIY it using the existing cables.

Yes. And good sound clarity from the old school Blaupunkt amp. But this will void the HU warranty.
If you worry about the warranty, just get the component speaker to replace the current door speaker. Warranty intact due to
no additional wiring required.

Quite decent for the cost. Even the amp installer was agree
Its a BPA series 4ch amp with run down housing but everything else is intact. Even the PCX 2 way speakers condition is bad as all connector has a thick shouldering mark but who cares as it works fine. I am okay without the woofer as my main aim is clarity. Volume seldom go up beyond 15.
During DIY installing the speaker to the door, I found out the noise absorbation material cannot be installed beyond the speaker line front and back or it may
caused sound distortion.

Anyone using Audiobank 4 gauge power cable? IMO, a good all round cable I even use it for grounding. Lol.
