Hi, I’ve been planning to upgrade the sound system to my Clio IV for a long time. Above all, the front right speaker is no longer right, so it’s about time. Unfortunately, I don’t know where to start in the area and I don’t know where to start. I read today that the original speakers are probably superior to the performance of the original radio. So does it make more sense to change the radio (I have the Media-Nav) or the speakers? What can you do for me? I also thought about getting a subwoofer. But that’s going to be very fun for a layman – I also don’t know if I could connect it. I looked at the back of the media-nav at Google, there is a white and a blue connection on the side, but I don’t see if the chinch connections are there. I hang a picture here from the back. Or maybe I should have the radio and the loudspre The price for all the fun I leave out first. Maybe someone has done this with the car and can report what is best? Thanks already in advance.
