Clio 200 speaker upgrade

Thinking about upgrading my speakers in the clio. Front and back, or just front. Undecided. What are the standard ones like? As I have some yellow pioneers up front and black in the rear. Is that just normal? Also what would people recommended for an upgrade? I've had a search but can't see any clear answer. And I'm a bit confused if the ones in the car are standard or not.
Anything appreciated, cheers:smile:
 
From experience I can tell you it wont matter what speakers you put in there because the stock stereo is complete rubbish
 
I would say youve got the pioneer replacements speaker and tweeters in the front, so there already uprated, and the backs are standard
