One lesson from my car purchase.
My Nexon Smart came with 2 factory fitted JBL speakers.
Before delivery, I got 2 additional JBL rear speakers installed after being told the sound quality would be similar.
It wasn't.
The rear speakers were barely audible, the sound quality was nowhere close to the OEM setup, and the speakers started vibrating at higher volumes.
Later, I was told these were aftermarket speakers and OEM speakers are different.
Looking back, it was a complete waste of money.
My takeaway - avoid aftermarket accessories. They never match OEM quality.
If a feature matters to you, just buy the higher variant.
