Removed stock speakers from my Sonet...I tested Focal and compared it with Infinity Reference as well as Kappa. My personal choice... Infinity reference, I changed both the front and the back and they sound a lot better, base is good does not sound too loud. Just use damping..
Bose speakers in kia cars are a scam, not sure about others. I have bought kia seltos 2024 GTX, done damping too. Not much improvement. Previously, i had a Ford ecosport with focal amp and focal auditor series. Stock bose speakers are not even close.
I am personally using Focal Auditor Components. It's amazing pairs but not for those who don't like bright sound signature. But they are awesome. I will try their Access series next time. But you should have gone with Access series difference would have been much more noticeable.
Using headphone, Focal sounds bassy and missing treble and mids even when car is parked and has no considerable noise, Bose sound balanced and detailed even when you are driving and must have surrounding traffic noise. For me, Focal is big failure.
I finally noticed a significant difference with the Opeth track. The strings are much more clear with the focal. The other ones it seemed like road noise (when moving) may have deterred from the Bose. It is nice to have good quality sound to help deal with the traffic chaos. Thank you.
