Hi all ! Below is my Car Audio System Details(Proton Wira Salon)

KenWood CD/MP3 player (KDC-8533)
KenWood 6X9" 2way rear speaker(KFC-6950ic
KenWood 6" Front speaker(KFC-1659s)
1 pair of tweeter
Brother's AMP (1600Watt) currently is using on two 10" KenWood Woofer(KFC-w2503)

My question is, This kind of setup need to change the front speaker to Component Set?
If change the Front speaker, the rear speaker need to change also?
The quality of sound will improve if i buy a AMP to support my rear and front speaker without change the speaker to component set??
normally i listen to all type of music,mostly R&B and hot song.But i also listen Kenny-G music.
So , Any idea? Thanks!
