307 Speakers

You may replace the fronts with 6.5" 'drivers and the rears with

5.25" (not sure on front splits - probably 1" tweeter), however I doubt it will make a lot of difference to be honest. Unfortuantely the poor sound quality stems from the internal amplifier of ye ol' RD3 Clarion headunit. Change this and you can leave the existing speakers...they actually sound good with a bit of power behind them. You could add in a small power amp in between your existing headunit and the existing speakers...but when I say small, I mean small...like 40RMS by 4 way at most. You'll also need to take your pride and joy back to the dealership so they can change the audio output of the headunit to low level. This involves connecting up your beast to the Diag 2000 system (I'm pretty sure only PUG dealers have this) and configuring the audio output through there. Hope I helped. Dan.

You have , Thanks m8, So it looks like i have to get a betterer cd head unit:-( it will have to wait a while though till i can save some pennies lol. I thought this may be the case but also does this mean if i change my head unit the remote steering track changer and dash display will no longer work with it or is there a way round this?

There are certainly ways around this (RE remote issue). Have a deeper look in this group about the topic, you'll find many reports. There are converters cables you can purchase for brands other than Clarion too. D
