I posted a few niggles a few weeks ago on the E89, one of which was the standard stereo, well now that I have lived with the car for a little while, I have been able to complete some top down tests, yes scientific stuff (I am a Mechanical Engineer after all lol), findings so far are: -
1) At 70 mph with the roof up the background noise is approximately 71 - 72 db
2) With the roof down this increases to 76 and up to – 81 db in traffic
3) Maximum volume through radio or CD is 83 db playing rock or pop
4) Maximum volume playing classical music is 79-80 db
5) Listening to spoken word books, at 78 db (audiobooks) is practically impossible at 70 mph with the top down
I think the results would be acceptable (just) if fitted to a conventional car but to a convertible it is very poor indeed. With this in mind I sent a letter to the dealer to complain.
The service desk contacted me last week and requested that I book the car in for test and evaluation, ok this is good, however they want it for a week, yes a whole week. Being slightly suspicious of dealers I am reluctant to agree, I do not believe there is actually anything at fault with the system or speakers it all seems to work, just not very loudly.
I could therefore be responsible for a huge bill if indeed there isn’t anything wrong, so two things, what do you lot think? Does anybody else have the standard stereo in the E89, if so what is the maximum sound pressure level in yours? Ok that was three
Thanks
