I have just fitted my replacement front speakers, which completes my upgraded stereo install. I have details of the Kenwood Custom fit speakers, but starting at the source: Kenwood KDC-PSW9521 MP3 MASK Headunit (Remote just in view at bottom). 10 Disc changer in the boot. Original Blaupunkt was good, but NEED MP3 and MASK! Amp + Sub: Kenwood KAC-625 2-Way Amp (Bridged for Sub) Kenwood KFC-W2500 10" Subwoofer in Ported Carpeted Box (in the boot - Ski Hatch cover removed) The Kenwood Components: The new speakers The new tweeters The downside was that perhaps due to MB changing them on my later car, the connections were not plug and play as they should have been. Sacrificing the old speakers though I neatly crimped the old OEM connectors on.
