I'm not looking for a very good u/g, but if a reasonable improvement can be
made by simply replacing the main speakers front and rear with some better
spec ones, I reckon my limited knowlege of car audio could cope with that.

With the E39, the one fundamental thing you must do is change the head
unit. The orignal unit is so poor that any changes you make elsewhere
within the system without first replacing the unit are likely to be a
huge waste of money (same goes with most of the BMW range).

On the other hand, I've known plenty of cases where an upgrade of just
the head unit to a decent quality high powered aftermarket unit (ie.
something like one of Alpine's 4 x 50w 'Microdynamics' units) has made
enough of a difference to leave the customer happy with the system.
