Don't be silly. The OEM sound system on the E39 is pretty poor given the
cost. The E34 had better sounding basic speakers from the factory.

Dunno if this applies to the X5, though.

BMW engineers, know nothing about anything do they?  That's why they came up
with a 10 speaker system designed to distribute the sound within the cabin
without resonances etc.

Obviously some cowboys like Transound* can boj in a systems that will sound
a lot better than original equipment ;-} LFTC!

The reality is that it is not normally worth messing around with original
equipment on a BMW - the only things I ever added were hand's free for a
portable phone in 1986 (factory fit on my current car), CB radio in 1988 and
a centre rear brake light when these became legal (standard fit on the last
two cars).  Oh yes and a little black box that sometimes went bleep in areas
of high electric field strength...

* as run by Leon Mazurek.  They managed to give one of my cars black and
crispy wiring when fitting a burglar alarm.  Mr. Mazurek has multiple
convictions, at least two of them unspent (source

business of this name may be unconnected with him.

Hi all,

I have purchased an E53 X5 (2005) which will be delivered next week. It has
a 10-speaker HiFi system but would like to replace these with "Boston
speakers".

My questions are:
1] Does anyone know which Bostons speakers will fit
2] Any idea how much this will cost

Thank you for your help.
Sonny
