What are the best speakers??

[Dgrange]

Hi,

I am taking my car in tomorrow to get the speakers upgraded at a local auto shop. My car is totally standard and I really want to keep it that way (no door speakers). I don't want to change the head unit so this just leaves me with the dash speakers. Can anyone give me some advice on what is the best speaker to upgrade with? I fully know the sound will not be great but it has to be better than what I have now.

Any suggestions would be good, has anyone upgraded and have recommendations.

Thanks all.....
