I agree! The stock head unit(Panasonic) sounds satisfying to me for now.
I was debating if I should touch them now or just leave it as is. The sounds is really not too bad, even the base. It sounds like I have a subwoofer installed in the trunk sometimes. I was thinking to take it easy on my listening habit now because my left ear is kind of weak and sensitive to highs. But who knows? Summer is coming??? Ahhhhh!
Good Luck!
