just caught up with this again, another tip for interested owners
using the foam inserts/covers for the rear speakers, turn them upside down, mark holes using your old speakers then sandwich them between the new speaker surrounds and the rear parcel shelf fixings. This will remove some vibration from the rear parcel shelf.
also you can improve the front setup by adding Dynaliner (Dynamat foam sandwich product that weighs next to nothing) - it completely deadens the whole door assembly and stops rattles.
The added bonus of the dynaliner is that you get more exhaust sound inside the car as you are hearing less road noise through the door metal
With my new Becker head unit and the speaker setup as documented I've ended up with exactly what was hoped for - a decent sounding, clear, punchy system with no real custom build work, no cutting of anything and no significant extra weight. Plus I have Nav, GSM with built-in SIM and an SD card for 4GB of music.
Perfect for the 1500 mile trip to Scotland in 3 weeks
