C5 upgrades

[sergiup]

I'm considering upgrading the speakers (and possibly the head unit at a later stage) in my Citroen C5 (59-reg). Has anyone had any experience with these Pioneer speakers, or others in the same range? Alternatively, does anyone know of a decent car audio place in Kent / SE London that wouldn't rip me off for a few upgrades? Thanks!

There is a place down in Welling, Car Alarms in Welling - Sounds Alarming which is good, there is another place M+F Electronics on the high st which does reasonable rates.
