E70 Speaker Hi Fi up grade?
 

Hi all, I've bought an 2007 x5 with Media package but as the standard 6 speaker disgrace, as with my e90 the pro radio and the standard speakers are in a word are C**P at a volume above quiet. My wife has a 2007 116i with the factory DSP and hi-fi speaker up-grade system and this is a superb system. So my Question is "does any one know of a suitable and possilbly easy speaker up-grade which can be employed in the X5?????":dunno: .
